AI Verdict
This is a budget smart door lock with five unlocking methods and Bluetooth app control, best for internal doors or those prioritizing convenience over advanced smart home integration.
This lock is a situational fit because its five unlocking methods, including a 0.2-second fingerprint reader and IC card support, offer convenience for specific use cases like internal doors. However, its reliance on Bluetooth for direct app control and the need for a separate gateway for Wi-Fi limit its utility for primary exterior doors or advanced smart home setups.
If you need true remote Wi-Fi access without extra hardware, look for a smart lock with integrated Wi-Fi, or one that explicitly states compatibility with your existing smart home hub.

Pros
- Offers five distinct unlocking methods: fingerprint, passcode, app control, IC cards (four included), and physical keys (two included).
- Fingerprint recognition is quick, unlocking the door within 0.2 seconds with a stated 99% recognition rate.
- The TUYA Bluetooth App allows remote locking/unlocking, E-code sharing, log record checking, and user management.
- Features an auto-lock function that can secure the door 5 seconds after closing, and a one-key anti-lock for privacy.
- Installation is guided by voice and designed to fit most US standard doors without requiring drilling.
- Supports up to 50 fingerprints and 100 IC cards for multiple users.
Cons
- Wi-Fi connectivity requires a separate Tuya Gateway, as the lock itself only uses Bluetooth for direct app control.
- Users must 'wake up' the lock before using fingerprint or passcode entry.
- The lock can temporarily freeze after multiple incorrect fingerprint or passcode attempts.
- The provided specifications do not include an IP rating for weather resistance, despite being made of metal.
- The product's connectivity is limited to Bluetooth 4.2.
Dimension Scores
The fingerprint sensor boasts a 99% recognition rate and unlocks in 0.2 seconds, which is above average for a budget lock, though users must 'wake up' the lock first.
Connectivity is limited to Bluetooth 4.2 for direct app control, requiring a separate Tuya Gateway for Wi-Fi access, which is below average for smart locks aiming for full remote functionality.
The Tuya Bluetooth App offers core smart lock functions like remote unlock (within range), log records, and user management, but lacks direct broader smart home integration without a gateway.
Constructed from metal, which is a standard material for door locks, but the product specifications do not provide any explicit IP rating for weather resistance.
Best For
- Bedroom doors or internal office doors where direct Wi-Fi isn't a necessity.
- Users who prefer multiple entry methods, especially fingerprint and IC cards, for quick access.
- Rental properties or shared living spaces needing easy user management and temporary code generation via Bluetooth.
Not Recommended For
- Main exterior doors requiring robust weather resistance or direct Wi-Fi integration without an additional gateway.
- Users who need seamless integration with broader smart home ecosystems beyond the Tuya Bluetooth app.
- Anyone who might forget to 'wake up' the lock before attempting to unlock it with a fingerprint or code.
Watch Out For
- You have to 'wake up' the lock by touching it before it will accept a fingerprint or passcode, which can be an extra step.
- The lock can enter a temporary 'froze' state if you try to unlock it multiple times with incorrect fingerprints or passcodes.
- While it has a metal build, the product specifications don't mention any specific weather resistance rating, so don't expect it to hold up to harsh outdoor elements.
- True Wi-Fi control for remote access outside of Bluetooth range requires purchasing a separate Tuya Gateway.

What Buyers Say
Many users found the installation process straightforward, often without needing to drill new holes, thanks to the voice guide. The multiple unlocking methods, especially the quick fingerprint reader and IC cards, are frequently highlighted as convenient. However, the need to 'wake up' the lock before using fingerprint or passcode entry is a recurring point of friction. The fact that true Wi-Fi control requires an additional Tuya Gateway also comes up, limiting its 'smart' capabilities out of the box for some.
“Honestly, it's pretty cool for my bedroom door, the fingerprint is fast when it works, but I keep forgetting to touch it first. And yeah, no direct Wi-Fi is kinda a bummer, but for the price, it's okay.”
Common Praise
- The voice-guided installation makes setup easy for most users.
- Fingerprint unlocking is fast, often working within 0.2 seconds.
- Having five different ways to unlock the door is very convenient.
- The auto-lock feature provides peace of mind when leaving in a hurry.
- The ability to manage users and share E-codes through the Tuya app is helpful for multiple occupants.
Common Complaints
- You have to touch the lock to 'wake it up' before using the fingerprint or keypad, which feels like an extra step.
- The lock can temporarily freeze if you enter too many incorrect fingerprints or passcodes.
- True remote Wi-Fi access requires buying a separate Tuya Gateway, it's not built-in.
- Some users experienced occasional fingerprint recognition errors, requiring multiple attempts.
Ownership Tips
- The 'wake up' requirement for fingerprint and passcode entry becomes a habit you have to consciously develop.
- Battery life is typical for a smart lock, but having the physical keys and emergency power option is a lifesaver when they run low.
- The Tuya app is functional for basic management but don't expect deep integration with other smart home platforms without a gateway.
- The anti-lock function on the backside handle is actually pretty useful for ensuring privacy when you're inside.
Frequently Asked Questions
Does this lock connect directly to my home Wi-Fi?
No, the lock connects via Bluetooth to your phone. For Wi-Fi functionality and remote access outside of Bluetooth range, you'll need to purchase a separate Tuya Gateway.
How many fingerprints and IC cards can I register?
You can register over 50 fingerprints and 100 IC cards with this smart door lock.
What happens if the batteries die?
If the batteries run out, you can still use the physical keys provided to unlock the door. There's also an option to plug in a battery pack for emergency power.
Is installation difficult, and do I need to drill new holes?
Installation is designed to be easy with a voice guide and generally does not require drilling, as it fits most US standard left and right-handed doors.
Can I set temporary codes for guests?
Yes, you can generate temporary passcodes via the TUYA Bluetooth app for guests, which can be automatically deleted after use.
Buying Guide
When looking at smart door locks, you need to think about how you actually want to use it. Don't just get caught up in 'smart' features; consider if it's for an interior or exterior door, how many people will use it, and if you need to control it when you're not home. The type of connectivity (Bluetooth, Wi-Fi, Zigbee) dictates its range and smart home compatibility.
Connectivity (Bluetooth vs. Wi-Fi)
Bluetooth means your phone needs to be close to the lock to control it, like using a TV remote. Wi-Fi lets you control it from anywhere with internet, like checking your security camera from vacation. This lock is Bluetooth, but can get Wi-Fi with an extra 'gateway' device.
Unlocking Methods
More methods mean more convenience and backup options. Fingerprint is fast, codes are good for guests, cards are quick, and physical keys are essential for emergencies, just like having a spare car key. This lock gives you five ways to get in.
Auto-Lock Function
This is like having someone automatically lock the door behind you after a set time. It's a security feature that prevents you from accidentally leaving your door unlocked when you're in a hurry.
Alternatives
If you need full remote Wi-Fi control without an extra hub, look for locks with integrated Wi-Fi. For outdoor use, prioritize models with a clear IP weather resistance rating.
