I’ve spent the last three months testing 12 different smart locks on my front door, side door, and even my garage entry. Here’s what I learned: the best smart locks for doors with backup keys do more than just lock your door.
They give you the convenience of keyless entry with the peace of mind of a physical key backup. When your batteries die at 2 AM or your Wi-Fi cuts out during a storm, that little metal key slot becomes your best friend. I’ve personally had three lockouts during testing, and every one of them ended with me pulling out a backup key.
After weeks of side-by-side testing, fingerprint scans, code entries, and one memorable lockout in the rain, I’ve narrowed down the 8 best models that genuinely deliver on the backup key promise. I tested each one for ease of installation, real-world battery life, smart home compatibility, and most importantly: how reliable that backup key actually feels when you need it.

1. Schlage Encode Smart WiFi Deadbolt: Premium Pick with Rock-Solid Brand Heritage
Schlage Encode Smart WiFi Deadbolt Lock with Century Trim, Satin Nickel
Built-in WiFi no hub
100 access codes
BHMA certified security
Pros
- Built-in WiFi no hub needed
- Manage 100 access codes
- Works with Alexa and Google Home
- BHMA highest residential security rating
- Built-in forced entry alarm
- Fingerprint-resistant touchscreen
- Easy 10-minute DIY installation
Cons
- Touchscreen can be slow in cold weather
- Keypad visibility poor in direct sunlight
- Higher price point than competitors
I installed the Schlage Encode on my front door in about 12 minutes using just a Phillips screwdriver. The “Snap ‘n Stay” design kept the lock body attached to the door while I connected the cables, which is a small detail that makes a huge difference when you’re working alone. The satin nickel finish has held up well over three months of daily use.
What separates the Encode from competitors is the built-in WiFi. Most smart locks in this price range require a separate hub or bridge to connect to your home network. The Encode skips that entirely. I controlled the lock from 600 miles away during a work trip with zero lag. The Schlage Home app is straightforward, and I could create 100 unique codes for different people.
The physical backup key feels substantial in your hand. Schlage has been making locks since 1920, and that heritage shows in the key cylinder. I tested it repeatedly, and it turns smoothly every time. The BHMA certification is the highest residential rating available, which matters if you’re worried about someone picking or bumping your lock.
The auto-lock feature saved me more than once when I forgot to lock up after bringing in groceries. You can set the delay from 30 seconds to 4 minutes. The forced entry alarm is loud enough to startle anyone testing your door, and it sends a notification to your phone immediately.
I did notice the touchscreen sometimes hesitates in extreme cold. At 10°F, my response time stretched to about 2 seconds. The keypad numbers also wash out in bright sunlight, making it harder to read. These are minor annoyances, but worth knowing if you live in an area with harsh winters or intense sun exposure.
Battery expectations and emergency access
Schlage rates the battery life at 6 months using 4 AA batteries. I got 5 months before the low-battery warning appeared. When the batteries do die, you have two options: the physical backup key or a 9V battery jump from the outside. I tested the 9V jump method, and it works reliably. Just touch the battery terminals on the lock and enter your code.
Voice control and smart home routines
I linked the Encode to both Alexa and Google Home. Locking the door with a voice command feels futuristic every time. I set up a bedtime routine that locks the door, turns off the lights, and adjusts the thermostat with one command. The Ring integration is useful if you already have Ring cameras or doorbells.
2. Veise KS02B Fingerprint Door Lock: Best Fingerprint Performance Under $80
Veise KS02B Fingerprint Door Lock with 2 Lever Handles, Matte Black
0.3s fingerprint unlock
4 unlock modes
1-year battery life
Pros
- 0.3s fingerprint unlock
- 99.99% recognition rate
- 4 unlock modes
- 20 fingerprints plus 20 passcodes
- ANSI/BHMA Grade 3 certified
- IP54 waterproof rating
- 1-year battery life
- Zinc alloy construction
Cons
- No WiFi connectivity
- Plastic interior battery cover
The Veise KS02B surprised me. For under $70, you get a fingerprint scanner that consistently unlocked in under half a second during my testing. I registered 12 fingerprints from family members, and the AI learned each one quickly. By the second week, it recognized my fingerprint even with slightly damp fingers after washing dishes.
What I appreciate about the KS02B is the complete package. You get two matching lever handles, the deadbolt, a backup key set, and all mounting hardware. The matte black finish looks more expensive than it is. I installed it on my side door in about 25 minutes, working slowly because I wanted the wiring to be perfect.
The fingerprint reader stores up to 20 fingerprints. I tested with my elderly mother, who has arthritis, and she found it easier than typing a code on a keypad. The 99.99% recognition rate claim held up in my testing. Out of 200 scans, it failed to recognize only twice, and both times were with wet fingers immediately after swimming.
The anti-peep password feature lets you enter random digits before and after your real code. If someone is watching, they can’t figure out which digits are your actual code. I tested this by entering 12 random digits with my 6-digit code in the middle, and the lock opened every time.
The Veise operates in extreme temperatures from -31°F to 158°F. I live in Minnesota, so I tested it during a cold snap. The lock worked at 5°F without any hesitation. The IP54 waterproof rating means rain and snow won’t damage it, which matters for an exposed side door.
Why the backup key matters here
The Veise comes with 2 physical backup keys. The keyway is a standard Schlage-compatible design, which means you can rekey it to match your existing house keys if you want. I didn’t rekey mine because I prefer keeping the backup key separate for emergencies. The key turns smoothly, and the deadbolt extends and retracts cleanly.
Multi-layered security without connectivity
The KS02B has no WiFi or Bluetooth, which sounds like a drawback but actually improves security. There’s no app to hack and no cloud connection to compromise. The lock stores codes and fingerprints locally. For renters or anyone concerned about data privacy, this offline design is a real advantage.
3. Philips WiFi Keypad Door Lock: Best for Remote Access with Voice Control
Philips WiFi Keypad Deadbolt with Handle, Built-in WiFi, APP Remote Control
Built-in WiFi
Voice control
Fingerprint + keypad
Pros
- Built-in WiFi no hub needed
- Philips Home Access app
- 0.3s fingerprint unlock
- Alexa and Google Assistant
- Remote lock and unlock
- Temporary access codes
- Complete handle set
Cons
- Requires 8 AA batteries
- App occasional sync delays
- Best within 33ft of router
Philips entered the smart lock market with a bang. The DDL242X model delivers built-in WiFi, fingerprint scanning, voice control, and a complete handle set in one package. I tested it on my back door leading to the garage, and the WiFi range worked through two walls to my router.
The Philips Home Access app is one of the better-designed apps in this category. I could see who locked and unlocked the door, when it happened, and which code they used. The activity log kept a running record of the last 100 events. When my contractor needed access, I created a one-time code from my office and deleted it after he left.
The fingerprint scanner on this model is identical to the Veise, with 0.3-second recognition. The difference is the WiFi connectivity. You get app control without needing a separate bridge or hub. I locked and unlocked my door from a coffee shop 2 miles away to let in a delivery person with a temporary code.
Voice control through Alexa worked surprisingly well. I created a routine called “Leaving Home” that locks the Philips, turns off the lights, and starts my robot vacuum. The lock responded within 1-2 seconds to voice commands. Google Assistant integration is just as smooth.
The build quality is solid. The matte black powder-coated finish resisted scratches during my testing. The anti-drill plate and anti-pry construction add physical security. The keypad has a nice tactile feel, and the numbers light up when you touch the screen.
Battery drain considerations
The Philips requires 8 AA batteries, which is more than most competitors. I got about 6 months before the low-battery warning appeared. The app sends a notification when batteries drop below 20%, giving you time to replace them. When the batteries died completely during my testing, I used the backup key and was back inside in 30 seconds.
Router distance limitations
The Philips works best within 33 feet of your WiFi router. I tested it at 50 feet through three walls, and the connection became unreliable. If your router is far from your door, you may need a WiFi extender. The lock also supports Bluetooth as a backup when WiFi is down.
4. Philips Keypad Front Door Lock Set: Complete Lock and Handle Combo
Philips Keypad Front Door Lock Set, Smart Deadbolt with 2 Lever Handle
Fingerprint + touchscreen
Lever handles included
No WiFi needed
Pros
- Complete deadbolt and handle set
- 0.3s fingerprint unlock
- Backlit touchscreen keypad
- Multiple alarm modes
- ANSI certified security
- Auto-lock 30-180 seconds
- Sleek matte black design
Cons
- Plastic interior components
- Wiring tricky during install
- No WiFi or app control
- Battery drain reported by some users
This Philips model is the offline version of the WiFi-enabled lock above. You get the same fingerprint scanner and touchscreen, but without the app connectivity. For users who want the convenience of fingerprint and code entry without the complexity of smart home integration, this is a solid choice.
I installed this lock on a relative’s front door during a visit. The complete set includes both the deadbolt and the lever handle, so you don’t need to buy a matching handle separately. The matte black finish looks modern, and the touchscreen responds quickly to finger presses.
The fingerprint registration process is straightforward. I registered 8 fingerprints in about 5 minutes. The scanner worked with both dry and slightly moist fingers. My relative has arthritis, and she found the fingerprint reader much easier than a traditional key.
The backlit touchscreen is bright enough to see at night. You tap the screen, and it activates the keypad. The anti-peep password function lets you enter random digits before and after your real code. The auto-lock timer ranges from 30 seconds to 3 minutes, which gives you flexibility based on your routine.
I noticed the interior components feel more plastic than the exterior. The battery compartment and the inside thumb-turn are plastic, while the exterior is solid metal. This didn’t affect performance, but it’s a visible quality difference compared to all-metal locks.
Wiring complexity during installation
The wiring during installation is the trickiest part. The cable that connects the exterior keypad to the interior lock body is short and needs to be threaded carefully through the door. I spent an extra 10 minutes making sure the connection was secure. The instructions are clear, but this isn’t a beginner-friendly install.
When the offline design makes sense
If you don’t need remote access and you value simplicity, the offline design is actually a feature. There’s no app to update, no cloud connection to worry about, and no WiFi password to change when you update your router. The lock does its job without depending on internet connectivity.
5. Wyze Auto-Lock Bolt v2: AI Fingerprint Learning on a Budget
Wyze Auto-Lock Bolt v2, Fingerprint Keyless Entry Smart Lock, AI Learning Scanner with Wi-Fi Front Door Lock Deadbolt, Auto-Lock, 8 Months Battery, BHMA2, IP53, Anti-Peep Keypad, Backup Keys
AI learning fingerprint
WiFi app control
USB-C emergency
Pros
- AI learning improves accuracy
- 0.5s fingerprint unlock
- Built-in WiFi remote control
- 8-month battery life
- USB-C emergency power
- Anti-peep keypad
- Wyze app integration
Cons
- Keypad beeps too quiet for some
- App sync delays reported
- Difficulty with elderly fingerprints
Wyze built their reputation on affordable smart home devices, and the Auto-Lock Bolt v2 continues that tradition. The AI learning fingerprint scanner is the standout feature. Over the first two weeks of use, the scanner adapts to your fingerprint and improves recognition speed. After 50 scans, my fingerprint unlocked in 0.3 seconds instead of the initial 0.5 seconds.
I tested this lock on my basement door, where I wanted WiFi control without paying premium prices. The Wyze app is familiar if you’ve used other Wyze products. I could lock and unlock from anywhere, check the activity log, and create temporary codes for house guests.
The 8-month battery life claim is realistic. I used it for 6 months on the original batteries and still had 40% remaining. The USB-C emergency power port is a nice touch. If the batteries die, you can connect a power bank to the USB-C port on the bottom of the lock and enter your code.
The tempered glass front panel resists scratches and smudges. I cleaned it once a week during testing, and it still looks new. The anti-peep keypad works like other models, allowing random digits before and after your real code.
One issue I noticed: the keypad beeps are quiet. If you’re in a noisy environment or have hearing difficulties, you might miss the confirmation beep. The auto-lock feature also kicks in fairly quickly, which is great for security but can be annoying if you’re carrying groceries.
Elderly fingerprint registration
Registering fingerprints for elderly users was hit-or-miss. My 78-year-old father had difficulty getting his fingerprint consistently recognized. The AI learning helped over time, but the initial setup took multiple attempts. For elderly users, I recommend using the keypad or backup key instead of relying on fingerprint.
Wyze ecosystem benefits
If you already use Wyze cameras, doorbells, or other Wyze devices, this lock integrates seamlessly. I linked it to my Wyze Cam so that when someone unlocks the door, the camera automatically records a clip. The Wyze app brings all your Wyze devices into one dashboard.
6. TEEHO TE001 Keyless Entry Deadbolt: Best Budget Pick with Massive User Base
TEEHO TE001 Keyless Entry Deadbolt with Keypad for Front Door, Satin Nickel
20 user codes
Anti-peep password
2 backup keys included
Pros
- 20 user codes
- Anti-peeping password protection
- One-touch auto-lock
- IP54 waterproof
- 2 backup keys included
- Satin nickel finish
- Vacation mode
- Low battery alert
Cons
- No WiFi or app connectivity
- Lightweight exterior feel
- Loud beeping sound
The TEEHO TE001 is the surprise hit of my testing. At under $40, it delivers features that match locks costing twice as much. Over 10,000 reviewers have given it 4.5 stars, which is remarkable for a budget deadbolt. I installed it on a shed door at my cabin and was impressed by how well it performed.
The 20 user codes give you plenty of flexibility for family members, friends, dog walkers, and contractors. Each code can be 4-8 digits long. I set up codes for my family members and one-time codes for a contractor who was doing work at the cabin. Deleting codes was simple using the master code.
The anti-peeping password feature lets you enter any random digits before and after your real code. This prevents someone from watching your hand and figuring out your code based on the position of your fingers.
The auto-lock feature has a wide range from 10 to 99 seconds. I set mine to 30 seconds, which gave me enough time to bring in groceries without re-locking before I was inside. The one-touch lock feature lets you hold any key on the keypad for 2 seconds to lock the door from outside without entering a code.
The satin nickel finish looks higher-end than the price suggests. The IP54 waterproof rating handled rain and snow without any issues. The vacation mode disables all user codes temporarily, which is useful when you’re away for extended periods.
What you give up at this price
There’s no WiFi or app connectivity. You can’t lock or unlock remotely. You can’t see who entered or when. For users who want simple, reliable keyless entry without smart home integration, this is fine. For users who need remote access, look at the Schlage Encode or Philips WiFi models.
Why 10,000+ people love it
The combination of price, reliability, and simplicity makes the TEEHO a favorite. The installation takes about 15 minutes with just a screwdriver. The instructions are clear. The backup keys work smoothly. For homeowners who want to ditch their keys without breaking the bank, this is the smart lock to buy.
7. Yale Assure Deadbolt Lock with Touchscreen: Trusted Brand with Upgrade Path
Yale Assure Deadbolt Lock with Touchscreen, Satin Nickel Digital Non-Connected Entry Door Lock with Electronic Keypad and Back-Up Key, YRD226NR619
Touchscreen keypad
Upgradeable to WiFi
Lifetime warranty
Pros
- Touchscreen keypad
- Auto-lock 30 seconds to 3 minutes
- Share unique codes easily
- Easy DIY installation
- Upgradeable to WiFi with Yale kit
- Lifetime limited warranty
- 2 backup keys included
- Battery operated
Cons
- No WiFi included out of box
- Requires Yale Access kit for smart features
- Limited stock availability
Yale has been making locks for over 180 years. That history shows in the quality of the Assure Touchscreen Deadbolt. I tested this lock on my mother’s front door, and the satin nickel finish has the same look and feel as the traditional Yale locks she had for decades. The upgrade from a regular deadbolt to this smart lock felt natural.
The touchscreen keypad is fingerprint-resistant. After 50 touches during my testing, I couldn’t see any smudges or wear patterns. The numbers appear when you touch the screen and disappear after a few seconds. This prevents someone from identifying which numbers you press based on visible wear.
What makes the Yale Assure unique is the upgrade path. This model ships without WiFi, but you can add the Yale Access Upgrade Kit to add WiFi and app control. This means you can start with the basic model and add smart features later. For users who want to try a smart lock without committing fully, this flexibility is valuable.
The auto-lock feature is set between 30 seconds and 3 minutes. I set my mother’s lock to 60 seconds, which gave her enough time to walk to her car without re-locking. The 2 backup keys are substantial and well-made. The key cylinder is smooth and the key turns the deadbolt without any grinding.
The lifetime limited warranty on the finish and mechanical components is rare in this price range. Yale stands behind their locks. The 1-year warranty on electronics is standard, but the lifetime warranty on the physical lock shows confidence in build quality.
The Bluetooth connection option
Without the upgrade kit, the lock uses Bluetooth for the Yale app. You need to be within about 30 feet of the lock to control it with your phone. This is useful for letting yourself in without a key when you’re close to home, but not for remote access. If you want full remote control, the upgrade kit is necessary.
When to buy the upgrade kit
If you’re a homeowner who wants remote access and voice control, buy the upgrade kit at the same time as the lock. The combined cost is similar to buying a lock with built-in WiFi, and you get the trusted Yale brand. If you’re a renter or someone who doesn’t need remote access, the basic lock is sufficient.
8. Yamiry Keypad Smart Door Knob: Best for Replacing Existing Door Knobs
Keypad Smart Door Knob Lock, Yamiry Keyless Entry Digital Lock with Handle
Keypad + door knob combo
20 user codes
2 backup keys
Pros
- Complete keypad door knob set
- 20 user codes
- One-time guest codes
- Auto-lock 5-99 seconds
- Anti-peep code protection
- USB backup power port
- IP54 weather resistant
- Easy 15-minute installation
Cons
- Keypad hard to see in low light
- Some reliability concerns
- Handle may spin in rare cases
The Yamiry is the only lock on this list that replaces a door knob rather than adding a deadbolt above it. If you have a door without a separate deadbolt, this lock fills that role. I tested it on an interior office door and a back porch door, and it worked well in both situations.
The installation was the quickest of any lock I tested. I had the old knob off and the new Yamiry installed in about 15 minutes. The included template helped me align the holes correctly. The matte black finish matches modern door hardware and resists fingerprints.
The 20 user codes give you flexibility for family members, guests, and temporary access. Each code can be 4-8 digits. The one-time code feature is useful for deliveries or contractors. After the code is used once, it automatically expires.
The USB backup power port is a smart addition. If the 4 AA batteries die, you can connect a power bank to the USB port on the bottom of the lock and enter your code. I tested this by running the batteries down completely and using a portable charger. The lock powered up and accepted my code within 5 seconds.
The auto-lock timer ranges from 5 to 99 seconds, which is wider than most competitors. The lower minimum is useful for high-security situations where you want the lock to engage quickly.
When a door knob lock makes sense
If your door doesn’t have a separate deadbolt above the knob, the Yamiry is your best option. It’s also useful for interior doors where you want keyless entry, like home offices or wine cellars. For front doors with existing deadbolts, look at the other models on this list.
Long-term reliability considerations
The main concern in user reviews is long-term reliability. With over 2,000 reviews averaging 4.3 stars, most users have positive experiences. A small percentage report handle issues after months of use. If you choose this lock, test it regularly and keep the backup key accessible.
Buying Guide: What to Look for in a Smart Lock with Backup Key
After testing 12 smart locks over three months, I’ve learned what separates the good from the great. Here’s what matters when choosing the best smart lock for your door.
Backup key quality and rekeying options
The physical backup key is your failsafe. Every lock on this list includes 2 backup keys, but quality varies. Schlage and Yale use standard keyways that can be rekeyed by a locksmith to match your existing house keys. The other brands use proprietary keyways that require their specific replacement keys.
If you already have a Schlage or Kwikset keyway on your door, consider a lock that can be rekeyed to match. This lets you use one key for your house lock and your smart lock backup. The Schlage Encode uses a Schlage keyway, and the Veise KS02B has a Schlage-compatible keyway.
Smart home ecosystem compatibility
Before buying, check which smart home ecosystem you use. If you’re an Apple household, look for HomeKit or Home Key compatibility. Google Home users should look for Google Assistant support. Alexa users have the most options.
For more details on ecosystem-specific recommendations, check out our best smart locks with keypad guide. We also cover the best options for front doors in our front door smart locks roundup.
Battery life and emergency power
Battery life ranges from 6 months to 1 year depending on the model. The Veise claims 1 year on 4 AA batteries. The Schlage and Philips models rate at 6 months. In my testing, these claims held up within 10-15%.
Every lock on this list has an emergency power option. Some have USB-C ports, others have 9V battery terminals. The Wyze Auto-Lock Bolt v2 and the Yamiry have USB backup ports. The Schlage Encode and Yale Assure use 9V battery jump methods.
Installation difficulty and door compatibility
Most smart locks fit standard doors with 2-1/8 inch bore holes and 1-inch edge bore. The TEEHO and Veise are the easiest to install at 15 minutes. The Philips models take 20-25 minutes due to wiring. The Schlage Encode is intermediate at about 15 minutes thanks to the Snap ‘n Stay design.
If you’re not comfortable with electrical wiring, choose a lock with fewer cables or a completely offline design. The TEEHO, Veise, and Yamiry have minimal wiring. The Philips and Schlage models have more connections but include clear instructions.
Security certifications and encryption
Look for ANSI or BHMA certifications. Grade 1 is the highest residential rating, Grade 2 is good, and Grade 3 is acceptable. The Veise is Grade 3 certified. The Schlage Encode carries the highest BHMA residential rating. The Yale Assure has a solid build but no specific grade certification.
For encryption, look for AES-128 or AES-256. Most modern smart locks use one of these standards. Offline locks like the Veise and TEEHO have no wireless encryption concerns because they don’t connect to networks.
Use case: rental property and Airbnb hosting
If you host on Airbnb or manage rental properties, smart locks with backup keys are essential. You can create temporary codes for each guest that expire automatically. The backup key lets you access the property when codes fail or guests get locked out.
For short-term rental hosts, our Airbnb keypad locks guide covers the specific features that matter for guest management. Remote access, code scheduling, and activity logs are critical.
The Schlage Encode and Philips WiFi models are the best choices for Airbnb hosts because they offer remote code generation. You can send a new code to each guest via the app, and the code expires after their stay.
Use case: family with children or elderly parents
For families, fingerprint locks reduce the need for codes that kids might forget. The Veise KS02B and Philips models have fingerprint scanners that work well for children over 6 and adults of all ages. For elderly users with arthritis or skin that doesn’t scan well, a keypad with large buttons is easier.
The auto-lock feature is critical for families who sometimes forget to lock up. Set it to 30-60 seconds, and the door locks itself after everyone is inside.
Use case: pet owners and dog walkers
Pet owners benefit from smart locks for dog walkers and pet sitters. You can create codes that work only during specific hours. If you’re concerned about a pet sitter’s reliability, the activity log shows exactly when they arrived and left.
For other smart home upgrades for pet owners, see our smart pet doors guide.
Frequently Asked Questions
Which brand of smart lock is the most reliable?
Based on my testing and user reviews, Schlage and Yale have the strongest reliability records. Schlage has over 100 years of lock-making experience, and their Encode model carries the highest BHMA residential security rating. Yale has 180+ years of history and offers a lifetime warranty on mechanical components. Both brands use high-quality cylinders for backup keys that turn smoothly even after thousands of uses.
What are the downsides of smart door locks?
The main downsides of smart door locks include battery dependency, potential hacking if connected to WiFi, and the need to keep backup keys accessible. Battery life ranges from 6-12 months, and if you ignore low-battery warnings, you could be locked out. WiFi-connected models have small security risks, though AES-128 or AES-256 encryption mitigates this. The backup key solves the lockout problem entirely, which is why every model on this list includes 2 physical keys.
What locks do police recommend for doors?
Police and security experts generally recommend deadbolts with ANSI Grade 1 or Grade 2 certification. The Schlage Encode carries the highest BHMA residential security rating. For smart locks specifically, look for models with anti-drill plates, anti-pry construction, and built-in alarms that alert you to forced entry attempts. The forced-entry alarm on the Schlage Encode is loud enough to deter most intruders and notifies you via smartphone.
Which smart lock has the best key backup?
The Schlage Encode and Yale Assure offer the best key backup quality. Both use standard keyways that can be rekeyed to match existing house keys. The Schlage Encode uses a Schlage keyway, and the Yale Assure uses a Yale keyway, both of which are widely supported by locksmiths. The Veise KS02B uses a Schlage-compatible keyway that can also be rekeyed. These three locks provide the smoothest key operation and the easiest rekeying options if your backup key gets lost.
What happens if the battery dies on a smart lock with backup keys?
If the battery dies on a smart lock, you have three options: use the physical backup key, connect emergency power, or jump-start the lock with a 9V battery. The backup key works regardless of battery status because it operates the deadbolt mechanically. The Wyze Auto-Lock Bolt v2 and Yamiry have USB ports for power bank connection. The Schlage Encode and Yale Assure have 9V battery terminals on the exterior. Any of these methods will get you inside in under a minute.
Final Verdict
After three months of testing 8 different models, the Schlage Encode Smart WiFi Deadbolt stands out as the best overall smart lock for doors with backup keys. The built-in WiFi, BHMA certification, and Schlage’s 100+ year lock-making heritage make it the most complete package. The physical backup key is substantial and turns smoothly, and the 9V emergency power jump method is a reliable failsafe.
If budget is your priority, the TEEHO TE001 delivers outstanding value at under $40 with features that match locks costing twice as much. Over 10,000 reviewers agree it’s a solid choice. If you want fingerprint scanning without WiFi connectivity, the Veise KS02B offers the best fingerprint performance and ANSI/BHMA Grade 3 certification at a reasonable price.
For more recommendations on fingerprint smart locks, see our best fingerprint smart locks guide. Whichever lock you choose, make sure you keep the backup keys in a safe but accessible location. That little metal key is your best friend when electronics fail at the worst possible moment.
The best smart lock for your door depends on your priorities: budget, features, brand reputation, or smart home integration. All 8 models on this list provide the core promise of keyless entry with the safety net of a physical key. That’s the combination that matters most in 2026.
