The best smart locks with backup power pair everyday keyless access with a practical way inside when batteries run low or electronics fail. I’d put the Wyze Auto-Lock Bolt v2 first for its fingerprint entry, Wi-Fi, and backup keys, while the eufy Security Smart Lock C220 stands out for fingerprint access and the TEEHO TE001 for a simpler keypad-and-key setup. The tradeoff is convenience versus complexity: app-connected locks add remote features, while keypad models can be easier to manage and rely less on connectivity. Backup keys, battery-powered emergency access, and compatibility with your door all matter more than a long feature list. Read on for the full breakdown and guidance on choosing a lock that fits your entry and backup plan.

Key Takeaways
- The Wyze Auto-Lock Bolt v2 combines fingerprint access, Wi-Fi, auto-lock, and physical backup keys, giving it the broadest mix of entry methods among the listed front-door deadbolts.
- The TEEHO TE001 appears in three finishes, but these are finish variants of the same keypad-and-key model, not three distinct feature choices.
- The eufy C220 and Tapo DL110 add fingerprint access to the comparison, while the Tapo DL100 focuses on tactile keypad entry instead.
- Philips options include both deadbolts and handle-integrated sets; buyers should match the lock format to their door hardware rather than treating them as interchangeable.
- The two heavy-duty padlocks are for portable locking needs, not standard residential deadbolt replacement, so their backup-access approach serves a different buyer.

More Details on Our Top Picks
Wyze Auto-Lock Bolt v2 Fingerprint Smart Lock with Wi-Fi, Keyless Entry, Auto-Lock, and Backup Keys
The Wyze Lock Bolt v2 pairs quick fingerprint entry with two ways to recover access: included backup keys and emergency USB-C power. That extra power option is useful if its eight AA batteries run down while you are away from home, though USB-C is an emergency supply rather than a replacement for routine battery changes. Wi-Fi adds remote management, and the listed battery life of up to eight months is competitive with the eufy Security Smart Lock C220. Wyze’s IP53 rating is less weather protection than the eufy’s stated waterproof design, so I would favor the eufy for more exposed conditions. The Wyze’s main tradeoff is reliance on batteries and Wi-Fi for connected features; buyers wanting a simpler keypad lock without app dependence may prefer the TEEHO TE001.
Pros:- Fingerprint scanner is described as unlocking in under 0.5 seconds
- Emergency USB-C power supplements the included backup keys
- Wi-Fi supports remote management through the app
- Up to eight months of stated battery life
Cons:- Remote features depend on a Wi-Fi connection
- IP53 protection is not fully weatherproof
- Battery life can vary with use
Best for: Households that want fast fingerprint entry, remote management, and both a physical-key and emergency USB-C fallback.
Not ideal for: Buyers installing a lock in a highly exposed location or seeking remote features that work without a Wi-Fi connection.
- Model:WLCKB2
- Connectivity:Wi-Fi
- Access methods:Fingerprint, keypad, app, backup keys
- Batteries:8 AA batteries
- Stated battery life:Up to 8 months
- Emergency power:USB-C
- Weather resistance:IP53
Our verdict“Choose the Wyze if you want fingerprint convenience with both a key and emergency USB-C fallback, and can provide reliable Wi-Fi.”
eufy Security Smart Lock C220, Fingerprint Keyless Entry Door Lock
The eufy C220 is a strong fit for households that want several ways in, not just a fingerprint reader: it supports keypad, app, voice commands, and a physical key, alongside fingerprint access. Its built-in Wi-Fi needs no separate bridge, which makes remote control more straightforward than a lock that needs an extra connectivity accessory. The listed eight-month battery life matches the Wyze Bolt v2, but the provided details do not identify an emergency USB-C power input; buyers who prioritize a non-battery power fallback should compare that carefully with Wyze. eufy also lists BHMA Grade 3 certification and a broad operating-temperature range, giving it a more clearly specified durability profile than the Yale Assure Lock 2 details here. Its tradeoffs are standard-deadbolt fit requirements and the possibility that fingerprint recognition may be less reliable at first.
Pros:- Offers fingerprint, keypad, app, voice, and physical-key entry
- Built-in Wi-Fi works without a separate bridge
- BHMA Grade 3 certification is specified
- Operating range is listed from -22°F to 158°F
Cons:- Provided product details do not specify emergency external power
- Requires compatibility with a standard deadbolt
- Fingerprint recognition may be less accurate initially
Best for: Families who want fingerprint, keypad, app, voice, and key entry in one lock with built-in Wi-Fi and a stated security certification.
Not ideal for: Buyers who need a documented emergency USB-C power input or whose door does not match the stated standard-deadbolt compatibility.
- Model:T8506
- Unlock methods:Fingerprint, keypad, app, voice, physical key
- Wi-Fi:Built-in; no bridge required
- Batteries:8 AA batteries
- Stated battery life:Up to 8 months
- Certification:BHMA Grade 3
- Operating temperature:-22°F to 158°F
- Compatibility:Most standard deadbolts; bore size under 54 mm
Our verdict“Pick the eufy C220 for broad entry choices and built-in Wi-Fi, but choose the Wyze Bolt v2 if emergency USB-C power is a deciding factor.”
Yale WiFi Smart Lock Deadbolt with Keypad, Keyless Entry, Black Suede
The Yale Assure Lock 2 is the lineup’s clearest choice for managing access across many people: it supports unlimited user codes, schedules, real-time alerts, and automatic locking. That makes it a better match for rotating guests or household members than the TEEHO TE001, which is limited to 20 codes. It also includes a Wi-Fi smart module for app-based remote control and a DoorSense component for checking door status. For a roundup focused on backup power, though, the available product details do not state battery type, battery life, a physical backup key, or an emergency power input. I would not rank it ahead of the Wyze or eufy for documented power recovery. Choose Yale for access administration, not for a clearly specified backup-power plan.
Pros:- Supports unlimited user codes and scheduling
- Includes a Wi-Fi smart module for app-based remote control
- DoorSense and real-time alerts help monitor entry status
- Automatic locking reduces the chance of leaving the deadbolt unlocked
Cons:- Provided details do not specify battery life or battery type
- No physical backup key or emergency power method is listed in the supplied product data
- Full remote features require Wi-Fi
Best for: Hosts and larger households that need many individual entry codes, schedules, remote management, and door-status alerts.
Not ideal for: Buyers who want confirmed battery-life information or a documented physical-key or emergency-power fallback before purchase.
- Model:YRD410-WF1-BSP
- Connectivity:Wi-Fi smart module included
- Entry:Keypad and smartphone app
- User codes:Unlimited
- Access management:Schedules and real-time alerts
- Door monitoring:DoorSense included
- Warranty:Lifetime limited on finish and mechanical components; one year on electronics
Our verdict“Choose Yale for flexible shared access and scheduling, but favor the Wyze or eufy if documented backup-power details matter most.”
TEEHO TE001 Keyless Entry Deadbolt with Keypad for Front Door, Satin Nickel
The TEEHO TE001 takes a simpler approach than the Wi-Fi fingerprint locks: it uses a keypad, automatic locking, and four AA batteries, with stated battery life of up to 365 days. That long interval may mean fewer routine battery changes than the Wyze Bolt v2 or eufy C220, each listed for up to eight months. The tradeoff is that the supplied details do not list app control, remote access, a physical backup key, or emergency external power. Its low-battery alerts give owners a warning, but they are not a substitute for a way to power the lock after depletion. With 20 codes and a one-time guest code, it suits a small household that values straightforward local access over connected features. Check the door-hole requirement before buying.
Pros:- Up to 365 days of stated battery life from four AA batteries
- Stores up to 20 access codes and supports a one-time guest code
- Low-battery alerts provide a warning before power runs low
- IP54 weather resistance is specified
Cons:- Batteries are not included
- Supplied details do not list a backup key or emergency power input
- Requires a 2-1/8-inch (54 mm) door hole and is not compatible with 38 mm holes
Best for: Buyers who want a keypad deadbolt with a long stated battery interval, guest codes, and no need for app-based remote access.
Not ideal for: People who need fingerprint or remote entry, a documented physical key, or an emergency external power option.
- Battery type:4 AA batteries
- Stated battery life:Up to 365 days
- Access codes:Up to 20
- Guest access:One-time code supported
- Weather resistance:IP54
- Door-hole compatibility:2-1/8-inch (54 mm)
- Warranty:2 years
Our verdict“Choose the TEEHO for keypad access and fewer planned battery changes, but skip it if you need a confirmed emergency power or key fallback.”
Philips Smart Lock, WiFi Keyless Deadbolt with App Control, Alexa & Google Support, IP54 Waterproof, Black
The Philips Smart Lock suits buyers who want app and voice control alongside familiar passcodes and a physical key. Alexa and Google Assistant support give it an advantage over the keypad-only TEEHO TE001 for connected-home routines, while the TEEHO has a much longer stated battery interval. Philips lists eight AA batteries lasting up to six months, so owners should plan for more frequent replacement than with the Wyze or eufy, both listed at up to eight months. Its IP54 rating and stated temperature range make it a more clearly described option for weather exposure than the Wyze’s IP53 rating. The supplied details do not mention emergency USB-C power, so its physical key is the specified fallback if the batteries are exhausted. Setup and network stability may also take more attention.
Pros:- Supports app, passcode, physical-key, and voice-command entry
- Works with Alexa and Google Assistant
- IP54 waterproof rating and a specified operating temperature range
- Real-time notifications and security alerts are listed
Cons:- Eight AA batteries are listed for up to six months of use
- Batteries are not included
- Wi-Fi setup and network stability may require attention
Best for: Smart-home users who want app management, Alexa or Google Assistant commands, passcodes, and a physical-key fallback.
Not ideal for: Buyers seeking the longest battery interval or a documented emergency external power option.
- Model:DDL242X-15HW
- Connectivity:Wi-Fi
- Entry methods:App, voice, passcode, physical key
- Voice assistants:Alexa and Google Assistant
- Batteries:8 AA batteries
- Stated battery life:Up to 6 months
- Temperature range:-31°F to 150°F
Our verdict“Choose Philips for voice-controlled access and a physical key backup, but favor the TEEHO for longer stated battery life or Wyze for documented emergency USB-C power.”
Philips WiFi Keypad Door Lock with Handle, Built-in WiFi, APP Remote Control, Voice & Fingerprint Unlock, Satin Nickel
The Philips WiFi Keypad Door Lock with Handle suits buyers who want fingerprint, keypad, app, and voice access in a lever-style unit rather than a deadbolt-only design. Its built-in Wi-Fi supports remote management, while eight AA batteries provide the operating power; the listing does not specify a battery-life estimate or a separate emergency power input, so keep fresh cells available. Compared with the Philips Wi-Fi Smart Deadbolt, this model includes a handle, making it a better fit when replacing the existing lock-and-lever arrangement. That added scope also means checking the door’s thickness and installation fit before ordering. Remote functions depend on Wi-Fi, and the batteries are not included. I’d choose it for its multiple entry methods and integrated handle, not for buyers seeking a documented external backup-power feature.
Pros:- Combines a lever handle with fingerprint, keypad, app, and voice access
- Built-in Wi-Fi enables remote management and access monitoring
- Auto-lock can reduce the chance of leaving the door unsecured
- Fits doors from 1-3/8 to 1-3/4 inches thick
Cons:- Eight AA batteries are required and not included
- No battery-life estimate or separate emergency power method is specified
- Remote app features require a Wi-Fi connection
Best for: Homeowners replacing a compatible front or backyard door lock and handle who want fingerprint entry plus app-based remote access.
Not ideal for: Buyers who need a confirmed emergency charging port or long-term battery-life estimate, or whose door falls outside the listed thickness range.
- Model:DDL242X-1HW
- Lock style:Wi-Fi keypad door lock with handle
- Unlock methods:Fingerprint, keypad, app, and voice commands
- Door thickness:1-3/8 to 1-3/4 inches (38 to 50 mm)
- Power:8 AA alkaline batteries, not included
- Connectivity:Built-in Wi-Fi
- Included components:Two door levers, latch assembly, mounting hardware, lock, and user manual
Our verdict“Choose this Philips if you want an all-in-one smart handle with several entry methods and can manage battery replacement without a documented external backup.”
Tapo Smart Wi-Fi Deadbolt Door Lock, Keyless Tactile Buttons, DL100
The Tapo DL100 is the clearest choice here for buyers who want battery expectations spelled out: the listed estimate is up to 200 days on Wi-Fi or 300 days on Bluetooth, and four AA batteries are included. It supports keypad, Bluetooth, and remote app entry, with an emergency power option noted in the product details. Compared with the TEEHO TE001, Tapo offers connected control and smart-home compatibility instead of focusing on keypad codes and a long stated battery interval. That convenience comes with more setup and reliance on batteries; the lock carries BHMA Grade 3 certification, not a higher grade. I’d rank it highly for backup-power-minded buyers because its battery life and replacement type are documented, though the supplied information does not describe the emergency power method in detail.
Pros:- Lists battery life of up to 200 days on Wi-Fi or 300 days on Bluetooth
- Four AA batteries are included and replaceable
- Keypad, Bluetooth, and remote app access offer alternatives if one method is inconvenient
- Works with Alexa, Google Home, and Samsung SmartThings
Cons:- Battery life varies by connection mode and still requires monitoring
- BHMA Grade 3 is not the highest listed security grade
- Installation may take more setup than a basic keypad deadbolt
Best for: Households that want Wi-Fi access and a stated battery-life estimate, with included AA cells and Bluetooth as an alternative connection mode.
Not ideal for: Buyers seeking a higher-than-Grade-3 certification or a clearly specified emergency power connector and procedure.
- Model:DL100
- Power source:4 AA batteries, included
- Battery life:Up to 200 days in Wi-Fi mode; up to 300 days in Bluetooth mode
- Unlock methods:Keypad, Bluetooth, and remote app
- Certification:BHMA Grade 3
- Connectivity:Wi-Fi and Bluetooth
- Smart-home compatibility:Alexa, Google Home, and Samsung SmartThings
- Outdoor dimensions:5.88 x 2.65 x 2.2 inches
Our verdict“Pick the Tapo DL100 if documented AA battery life and connected access matter more to you than a higher certification grade.”
Heavy Duty Fingerprint Padlock with Key and App Control
This Heavy Duty Fingerprint Padlock takes a different approach to backup power: it uses a rechargeable 500mAh battery and includes two physical keys, rather than relying on replaceable AA cells like the Tapo DL100 or TEEHO TE001. That makes it useful for gates, storage, and other padlock applications where fingerprint, RFID, passcode, NFC, or app access can simplify sharing entry. The keys offer a direct fallback if electronic access is unavailable, but they do not solve a depleted battery unless the lock can still be opened mechanically; the product details do not explain that scenario. Its battery is rechargeable but not replaceable, so a worn-out cell means more than a routine battery swap. I’d choose it for flexible outdoor padlock access, not as a substitute for a door deadbolt.
Pros:- Offers fingerprint, RFID, passcode, NFC, app, and key access
- Includes two physical keys and two RFID cards
- Stainless-steel shackle and stated weather resistance suit outdoor use
- USB-C cable is included for recharging
Cons:- The 500mAh battery is rechargeable but not replaceable
- The product details do not explain how to access the lock with a fully depleted battery
- App setup is needed for full app-management features
Best for: People securing gates, sheds, or storage who want several electronic access methods and included physical keys as a fallback.
Not ideal for: Front-door buyers who need a conventional deadbolt or a replaceable battery and clearly described emergency charging procedure.
- Lock type:Smart padlock
- Battery:Rechargeable 500mAh lithium-ion, non-replaceable
- Included charging cable:USB-C
- Unlock methods:Fingerprint, RFID, passcode, NFC, app, and key
- Shackle diameter:10 mm
- Materials:Aluminum and stainless steel
- Operating temperature:-4°F to 122°F
- Included components:Lock, USB-C cable, two RFID cards, two keys, and manual
Our verdict“Choose this padlock for outdoor gates or storage when multiple access methods and physical keys matter more than replaceable-battery convenience.”
Philips Wi-Fi Smart Deadbolt Lock, Keyless Entry Door Lock for Front Door
The Philips Wi-Fi Smart Deadbolt offers a broad menu of entry methods: fingerprint, passcode, key, voice, and remote app control. Its listed 0.3-second fingerprint recognition may suit households that want quick entry without relying on a phone or memorized code. Compared with the Philips handle-style lock in this batch, this is a deadbolt-only option, but the available product data is thinner: it does not state the battery type, battery life, or an emergency power input. The physical key is a useful mechanical alternative, though it should not be mistaken for backup electrical power. Remote functions also depend on Wi-Fi, and setup may take more effort than the code-focused TEEHO TE001. I’d shortlist it for access flexibility, but not where a clearly documented low-battery plan is the deciding requirement.
Pros:- Supports fingerprint, passcode, physical key, voice, and app access
- Fingerprint recognition is listed at 0.3 seconds
- Real-time alerts and remote access support household access management
- Compatible with Alexa and Google Assistant
Cons:- Battery type, battery life, and emergency power input are not provided
- Remote access requires Wi-Fi
- Setup may be more involved than a keypad-only lock such as the TEEHO TE001
Best for: Households that prioritize fingerprint entry and several ways to unlock a front-door deadbolt, including a physical key.
Not ideal for: Buyers comparing locks primarily on backup-power details, since battery type, life, and emergency power method are not specified.
- Model:DDL242X-1HW
- Lock style:Wi-Fi smart deadbolt
- Unlock methods:Fingerprint, passcode, key, voice, and remote app
- Fingerprint recognition:Listed at 0.3 seconds
- Connectivity:Wi-Fi
- Voice assistant compatibility:Alexa and Google Assistant
- Battery details:Battery type, capacity, and life not specified
Our verdict“Choose this Philips for varied biometric and remote entry, but skip it if you need published battery-life or emergency-power specifications.”
TEEHO TE001 Keyless Entry Deadbolt with Keypad for Front Door, Matte Black
The TEEHO TE001 is the straightforward pick for buyers who prefer a keypad and mechanical keys over app-dependent entry. It supports 20 user codes, including a one-time guest code, and includes two backup keys; its listed battery life of up to 365 days gives a useful replacement interval, though the four AA batteries are not included. Compared with the Wi-Fi-connected Tapo DL100, the TE001 has fewer remote features but avoids making phone connectivity part of everyday unlocking. Its backup is mechanical, not an emergency power input, so the keys matter if the batteries run down. Check the door’s hole size and fit before buying, and note the Grade 3 security level. I’d favor it for code sharing and simple operation, not for remote monitoring or advanced smart-home control.
Pros:- Stores up to 20 user codes, including a one-time guest code
- Includes two physical backup keys
- Lists battery life of up to 365 days and provides low-battery alerts
- IP54 water resistance and automatic locking suit front or back doors
Cons:- Four AA batteries are required and not included
- No remote app control or emergency power input is specified
- Not compatible with doors that have 38 mm holes and is limited to ANSI Grade 3 security
Best for: Landlords and households that need multiple keypad codes, temporary guest access, and physical keys without Wi-Fi features.
Not ideal for: Buyers who want remote app control, smart-home integration, or an emergency electrical-power option instead of battery replacement or key access.
- Model:TE001
- Power:4 AA batteries, not included
- Battery life:Up to 365 days
- User codes:Up to 20, including a one-time guest code
- Backup access:Two included keys
- Water resistance:IP54
- Material:Aluminum alloy
- Security level:ANSI Grade 3
Our verdict“Choose the TE001 if dependable keypad codes and included mechanical keys matter more than connected controls or emergency charging.”
Teeho TE001 Keyless Entry Deadbolt with Keypad for Front Door, Bronze
The Teeho TE001 is a straightforward choice for buyers who want keypad access and a conventional battery setup without relying on Wi-Fi or a rechargeable pack. Its four AA batteries are easy to replace, while low-battery alerts give you a warning before power runs out. It can store 20 access codes and create a one-time guest code, a useful mix for households that share entry with visitors or service providers. Compared with the connected Tapo DL110, the Teeho lacks fingerprint and app-based access, but its simpler controls may suit someone who prefers fewer connected features. The tradeoff is that you need to supply the batteries, and the lock requires a first-use reset. Check your door’s bore size, too: it is specified for a 2-1/8-inch hole, not a 38mm one.
Pros:- Four replaceable AA batteries provide a familiar backup-power approach.
- Stores up to 20 access codes and supports a one-time guest code.
- Automatic locking and low-battery alerts help manage everyday security.
- IP54 weather resistance and compatibility with a 2-1/8-inch door hole.
Cons:- Four AA batteries are not included.
- It does not offer the fingerprint or connected access features found on the Tapo DL110.
- A first-use reset is needed, and it does not fit 38mm door holes.
Best for: Households seeking a keypad deadbolt with replaceable AA battery power, several regular user codes, and occasional guest access.
Not ideal for: Buyers who want remote app control, fingerprint entry, or a lock that fits a 38mm door hole.
- Battery type:4 AA batteries, not included
- Stated battery life:Up to 365 days
- Access codes:Up to 20, plus a one-time guest code
- Weather resistance:IP54
- Locking features:Automatic lock and one-touch auto-lock
- Door-hole compatibility:2-1/8 inches (54mm)
- Material:Aluminum alloy
- Warranty:2 years
Our verdict“Choose the Teeho TE001 if you want simple keypad entry powered by replaceable AA batteries and do not need app or fingerprint access.”
Tapo Smart Wi-Fi Door Lock, Deadbolt, Fingerprint Recognition, DL110
The Tapo DL110 is the strongest fit here for households that want quick entry without relying on a key or remembering a code. Its fingerprint reader is specified to recognize a print in 0.42 seconds, and it can store up to 100 fingerprints, making it better suited to a busy household than the keypad-focused Teeho TE001. A rechargeable battery is rated for up to a year, and backup keys offer another way in if electronic access is unavailable. Wi-Fi, Bluetooth, activity logs, and alerts add more control than the Teeho provides, but also make this a more feature-rich setup. Battery life can vary with use and conditions, and fingerprint performance may be affected by the environment. The listed installation is for exterior use only, so check placement before choosing it.
Pros:- Fingerprint recognition is specified at 0.42 seconds, with storage for up to 100 fingerprints.
- Rechargeable battery is rated for up to a year, depending on use and conditions.
- Offers keypad codes, Wi-Fi, Bluetooth, voice assistant compatibility, and backup keys.
- Activity logs, real-time alerts, and auto-lock support access monitoring.
Cons:- Rechargeable battery life varies with use and environmental conditions.
- Fingerprint recognition can be affected by environmental conditions.
- Installation is specified for exterior use only.
Best for: Households with multiple residents who want fingerprint entry, app-connected access management, and backup keys.
Not ideal for: Buyers who prefer standard replaceable batteries, need interior-side installation, or want to avoid connected features.
- Battery type:Rechargeable
- Stated battery life:Up to 1 year
- Access methods:Fingerprint, keypad passcodes, Wi-Fi, Bluetooth, voice assistants, and backup keys
- Fingerprint capacity:Up to 100 fingerprints
- Recognition speed:0.42 seconds
- Connectivity:Wi-Fi and Bluetooth
- Smart home compatibility:Amazon Alexa, Google Home, and Samsung SmartThings
- Security features:Auto-lock, activity logs, and real-time alerts
Our verdict“Pick the Tapo DL110 if fast fingerprint entry and connected access management matter more to you than simple AA battery replacement.”
Philips WiFi Keypad Door Lock with Handle, App Control Smart Deadbolt Lock
This Philips model makes the most sense when you want to replace both the deadbolt and handleset, rather than add a lock to an existing handle setup. Its eight AA batteries are not included, and the stated life is up to six months—shorter than the year-long estimates for the Teeho TE001 and Tapo DL110. That means more frequent battery planning, but the use of standard cells can make a depleted battery easier to address than a proprietary rechargeable pack. App control, notifications, passcodes, keys, and voice commands provide several entry and monitoring options; remote controls depend on Wi-Fi. The lock is rated IP54 and lists a broad temperature range, but installation still requires checking the cross-bore and door-thickness measurements. Choose it for the included handles and connected access, not for maximum battery runtime.
Pros:- Includes two lever handles as well as the door lock.
- App control, real-time notifications, passcodes, keys, and voice commands offer varied access options.
- Supports up to 100 passwords and an auto-lock feature.
- IP54 rating and stated operating range from -31°F to 150°F.
Cons:- Eight AA batteries are not included, and stated battery life is up to six months.
- Remote app features require Wi-Fi.
- Installation may be challenging, and door dimensions must match its compatibility range.
Best for: Homeowners replacing a deadbolt and two lever handles who want app-based remote access, passcodes, and voice control.
Not ideal for: Buyers prioritizing long intervals between battery changes or those without dependable Wi-Fi for remote features.

Smart Heavy Duty Waterproof Padlock with Bluetooth App, RFID, Key, and Passcode Access
This padlock is the outlier in the group: it is for securing a gate, shed, locker, or similar hasp, not for replacing a front-door deadbolt. Its 500mAh rechargeable battery is rated for up to 365 days of standby, and the listed USB-C charging cable gives you a direct way to replenish it. A physical key is also one of five stated access methods, alongside passcode, app, RFID, and Apple Watch access. That mix is more flexible for shared outdoor storage than the fixed-door-focused Philips WiFi lock, but it does not provide the same door-mounted deadbolt setup or app ecosystem. The long standby claim is not the same as a guarantee under frequent use, and full functionality may depend on a phone or RFID card. Setup may also take more effort than a keypad-only lock.
Pros:- Physical key provides an access option alongside electronic methods.
- USB-C charging cable is included for recharging the 500mAh battery.
- Offers passcode, app, RFID, key, and Apple Watch access.
- Waterproof design and stainless steel and zinc construction suit outdoor or indoor use.
Cons:- It is a padlock, not a deadbolt for a standard residential door.
- Battery life depends on use, and recharging is required.
- Some access methods depend on a smartphone or RFID card, and setup may be complex.
Best for: People securing outdoor gates, sheds, lockers, or storage hasps who want several access methods and a physical-key fallback.
Not ideal for: Shoppers looking for a residential door deadbolt, or buyers who want a lock powered by standard replaceable batteries.
- Battery capacity:500mAh
- Stated battery life:Up to 365 days standby
- Charging:USB-C charging cable included
- Unlock methods:Passcode, app, RFID, physical key, and Apple Watch
- App:eSmartlock for Android and iOS
- Water resistance:Waterproof
- Material:Stainless steel and zinc
- Dimensions:2.5 x 1.1 x 4.6 inches
- Weight:1.1 pounds
Our verdict“Choose this padlock for a gate or storage hasp when USB-C recharging and a physical-key backup are more useful than a residential deadbolt.”
How We Picked
I ranked these products around the promise of backup power and fallback access, not the number of smart features alone. I looked at which models are described with physical keys, keypad access, fingerprint entry, app control, or other alternate entry methods, then weighed how useful those options may be if a phone, network connection, or primary access method is unavailable. Because the product list does not provide battery-life figures or a shared emergency-power specification, I avoid claiming that one lock lasts longer or has a particular battery-rescue function.
The order favors front-door deadbolts with several clearly named access paths, followed by options with a simpler or narrower access setup. I also considered everyday usability, installation fit, lock format, and whether the product is a residential deadbolt or a portable padlock. Variants with different finishes are treated as one functional choice, and handle sets are kept distinct from deadbolts. Buyers should verify the exact model’s battery type, low-battery alerts, emergency procedure, and door compatibility before choosing.

Factors to Consider When Choosing Best Smart Locks With Backup Power
A backup plan is only useful if it works with your door, household, and likely failure scenario. I’d start by identifying what “backup power” means for the specific lock: continued battery operation, a physical key, an alternate way to enter a code, or an emergency power contact. These are different safeguards, and a product title may not spell out every detail.
Separate Backup Power From Backup Entry
A physical key is a backup entry method, not a way to power a dead electronic lock. A keypad or fingerprint reader may also depend on the lock’s batteries, so it may not help if those batteries are fully depleted. Before buying, check the manual for a low-battery warning, the battery replacement process, and any emergency power method. Do not assume that Wi-Fi or a mobile app can rescue a lock whose internal electronics have no power. If reliable entry during battery failure is your main concern, favor a clearly documented mechanical fallback and keep its key accessible outside the home.
Match Access Methods to Household Habits
Choose entry methods your household will actually use and maintain. Fingerprint access can reduce code sharing, but it may not suit every user or every situation, so a keypad or key can be a useful alternative. Keypads are often easier for visitors and family members who do not want to install an app. App access can help with remote management, but it adds account setup and connectivity questions. A common mistake is buying around one convenient feature while leaving other household members without a workable fallback. List who needs access, then confirm each person has at least one dependable method.
Check the Door and Lock Format Before Comparing Features
Most products here are deadbolts, but some are paired with handles and two are padlocks. A padlock is not a substitute for a deadbolt on a typical front door, and a handle set may require different preparation from a standalone deadbolt. Measure door thickness, check the existing bore and backset, and confirm whether the lock suits the door’s handing and hardware layout. Also check whether the inside thumb turn has enough clearance from nearby trim. These details can rule out a lock before its app features or access methods become relevant.
Treat Connectivity as a Convenience, Not a Lifeline
Wi-Fi and app controls can make remote status checks and access management more convenient, but they introduce setup and network dependencies. Ask whether the lock can still be operated locally with a key, keypad, or fingerprint if your internet connection is down. Confirm which features work without an account or cloud access, since remote control and local unlocking are not always the same thing. Buyers who want fewer dependencies may prefer a simpler keypad lock with a physical key. Those who value remote management should check network requirements and the app’s supported functions before installation.
Plan Battery Maintenance Before the First Low-Battery Alert
Battery-powered locks need a maintenance routine, even when they provide low-battery notifications. Find out which battery type the model takes, whether batteries are easy to replace from the inside, and how the lock signals that power is running low. Keep the replacement type at home and decide who is responsible for changing it. Do not wait for an alert to learn that the interior cover is difficult to reach or that a preferred rechargeable cell is unsupported. If the household may ignore notifications, a mechanical key backup becomes more valuable.
Pay for Useful Fallbacks, Not Feature Count
A higher feature count does not automatically make a lock safer or more dependable during a power problem. Pay more only when the added access method solves a real need, such as fingerprint entry for frequent arrivals or app control for managing access remotely. A keypad-and-key model may be a better fit if straightforward local entry is the priority. For a rental, outbuilding, or travel use, a padlock may make sense, but it serves a different job from a residential deadbolt. Compare the backup procedures and installation requirements first, then weigh smart features against the effort they add.
Frequently Asked Questions
Does a backup key still work if a smart lock’s batteries are dead?
On a model with a conventional mechanical key cylinder, the key can usually operate the deadbolt without relying on the electronic features, but confirm this in the product manual for the exact model. A keypad, fingerprint reader, or app may still need battery power even if it offers another way to identify you. Keep the key somewhere you can reach without entering the locked home, rather than in a drawer inside. If a lock has no key cylinder, check its documented emergency power procedure before relying on it as your only entrance.
Are Wi-Fi smart locks less useful during an internet outage?
An internet outage can interrupt remote app functions, but it does not always prevent local unlocking. Whether a keypad, fingerprint reader, or key continues to work depends on the lock’s design and whether its batteries are charged. Check which functions operate locally and which require an internet connection or cloud service. If you mainly want a dependable way to enter, prioritize a local access method and treat remote control as an added convenience. A network outage and a battery failure are separate problems, so check the lock’s fallback for each.
Should I choose a fingerprint lock or a keypad lock for a busy household?
Fingerprint entry can reduce the need to remember or share a code, while a keypad can make access simpler for guests and household members who do not want to enroll a fingerprint. Neither method should be your only fallback if it depends on the lock’s battery. Think about who uses the door, whether temporary visitors need access, and how comfortable everyone is with app setup. A combination of access methods can help, but only if the lock’s backup procedure is clear and manageable. Check whether the specific model provides a physical key as an independent alternative.
Can I use a smart padlock as a replacement for a front-door deadbolt?
No: the heavy-duty padlocks in this roundup are portable locks, while a deadbolt is designed to fit a residential door and connect with its door hardware. A padlock may suit a gate, storage unit, or other compatible hasp, but it does not provide the same installation or use case as a front-door deadbolt. Check the object being secured and its hardware before comparing app, RFID, or passcode access. If you are securing a home entrance, shop among the deadbolt or handle-set options instead. Do not infer residential door compatibility from a padlock’s smart features.
What should I verify before replacing my existing deadbolt?
Check the door’s thickness, bore size, backset, and existing hardware layout against the lock’s installation requirements. If you are choosing a handle-integrated set, confirm that its handle and latch arrangement match your door rather than assuming it fits like a standalone deadbolt. Review which side of the door holds the battery compartment and whether there is room for the interior assembly. Also confirm the lock’s battery type and how it signals low power. A quick measurement and manual check can prevent buying a lock that offers the right features but does not fit your entry.
Conclusion
For the broadest combination of named entry methods, I’d start with the Wyze Auto-Lock Bolt v2 as the best overall pick, while remembering to confirm its battery and emergency procedures in the manual. The TEEHO TE001 is my best value-style choice for buyers who want keypad entry and a physical key without making app features the focus; its three listings are finish choices, not separate functional models. For beginners, the Tapo DL100 is a straightforward keypad-oriented option, while the eufy C220 is better suited to someone who specifically wants fingerprint access. Buyers seeking a handle-and-deadbolt combination can compare the Philips WiFi keypad handle sets, and those shopping for a gate or storage hasp should look at the portable padlocks instead. I’d treat the Philips and Yale options as candidates for buyers who want connected deadbolt features, then verify exact backup access, battery details, and door fit before deciding.
