AI Verdict
This is a zinc-material biometric door knob with Wi-Fi and app control, storing up to 100 fingerprints, best for internal doors or low-security areas.
This lock is a situational fit because its Wi-Fi connectivity and biometric access are convenient for specific scenarios like internal doors or rental properties. However, its budget price band and general Tuya platform concerns mean it's not ideal for high-security main entry points.
If you need higher security or more robust smart home integration, look for locks with a higher security rating (e.g., ANSI Grade 1) and native support for platforms like HomeKit, Z-Wave, or Zigbee.

Dimension Scores
The 508 DPI fingerprint sensor boasts a recognition rate exceeding 98% within 0.5 seconds, which is quick and accurate for its price point.
It features direct Wi-Fi connectivity for remote control, which is a step up from Bluetooth-only models, but its range is limited by typical home Wi-Fi coverage.
The lock uses the Tuya app for control, offering user management and access records, but user feedback suggests the app can be clunky or less intuitive for certain functions like fingerprint enrollment.
Constructed from zinc material, it provides a basic level of durability, but there's no specific mention of weather resistance ratings for outdoor use, suggesting it's best for sheltered or indoor applications.
Best For
- Internal doors in homes, like bedrooms or home offices, needing quick, keyless access.
- Apartments or Airbnb units where temporary access codes and remote management are useful.
- Users who prioritize fingerprint access and basic app control over advanced smart home integration.
- Anyone looking for a budget-friendly keyless entry solution for low-to-medium security needs.
Not Recommended For
- Main exterior entry doors requiring high-level security due to general concerns about Tuya lock robustness.
- Users expecting seamless integration with non-Tuya smart home platforms.
- Anyone who needs a lock that includes its own power source or rechargeable battery.
Watch Out For
- The Tuya app can be clunky; some users report difficulty finding where to add fingerprints, suggesting an older, more straightforward app version was better.
- You'll need to buy four AA batteries separately, as they aren't included, which can delay installation.
- The lock might announce actions with voice prompts, which isn't always desired and can't always be disabled easily.
- Despite Wi-Fi connectivity, the overall security and feature set might not match more established smart lock brands, leading to potential trust issues for critical entry points.

What Buyers Say
The biggest takeaway from user feedback is that while the fingerprint recognition is surprisingly fast and accurate, the Tuya app experience can be a bit of a headache, especially when trying to set up new fingerprints. People love the convenience of not needing keys and the ability to manage access remotely, which is a huge plus for rentals. However, there's a recurring theme of caution regarding using these types of locks on main entry doors due to general security perceptions of budget smart locks. The fact that it doesn't come with batteries is a minor but annoying detail that catches some people off guard during installation.
“Okay, so the fingerprint thing actually works really well, like, surprisingly fast, but trying to get new fingerprints added in the app is a total pain, and seriously, no batteries included? Come on.”
Common Praise
- Fingerprint recognition is fast, often unlocking in under 0.5 seconds.
- The ability to generate temporary access codes remotely is super handy for guests or service providers.
- Installation is straightforward and can be done quickly with just a screwdriver.
- Having multiple ways to unlock (fingerprint, app, key) provides good flexibility.
- The adjustable latch ensures it fits various standard door sizes.
Common Complaints
- The Tuya app can be confusing or slow, making fingerprint setup frustrating.
- Concerns about the security level for primary exterior doors, with some recommending it only for internal use.
- Batteries are not included, which means an extra trip to the store before installation.
- Voice prompts from the lock can be intrusive and aren't always easy to disable.
- Some users feel the overall build quality, while zinc, isn't as robust as higher-end brands.
Ownership Tips
- You'll quickly learn to keep spare AA batteries around, as the lock doesn't give much warning before they die.
- The remote access features are genuinely useful for letting people in when you're not home, but you'll mostly stick to fingerprint for daily use.
- The voice prompts, while sometimes annoying, do confirm when the door is locked or unlocked, which can be reassuring.
- You'll probably end up using the mechanical key more than you thought, especially if you're not always connected to Wi-Fi or if the app acts up.

Buying Guide
When you're looking at smart door locks, don't just focus on the 'smart' part. Think about where you're putting it. For a bedroom or office, convenience is key, and a fingerprint lock like this is awesome. For your front door, you need to weigh the convenience against how much security you actually feel comfortable with, especially with budget brands. Consider how often you'll use the app versus the fingerprint, and if you're okay with buying batteries separately.
Fingerprint Sensor (508 DPI, 0.5s recognition)
This tells you how quickly and accurately the lock will read your finger. A 508 DPI sensor with 0.5-second recognition means you won't be standing there jiggling your thumb for ages; it's almost instant, like unlocking your phone.
Connectivity: Wi-Fi
Wi-Fi means you can control the lock from anywhere with an internet connection, not just when you're standing next to it with Bluetooth. This is crucial for remote access, like letting a friend in while you're at work.
Material: Zinc
Zinc is a common material for door hardware, offering decent durability and a solid feel. It's not as heavy-duty as steel, but it's perfectly adequate for most interior doors and provides a good balance of cost and strength.
Alternatives
If this lock doesn't cut it for your main entry, look for smart deadbolts with higher security ratings (like ANSI Grade 1), or models from established lock brands that offer more robust app ecosystems and weather resistance.
