AI Verdict
A budget biometric door knob with Bluetooth app control and physical key backup, designed for interior doors needing basic access management.
This lock is a situational fit because its 3-in-1 biometric, app, and key unlock methods, combined with a rechargeable battery, offer convenience for interior doors. However, the Bluetooth-only app control and lack of an integrated keypad limit its utility for more demanding security needs or remote management.
If you need remote Wi-Fi control or a keypad for guests, look for models with integrated Wi-Fi or a built-in keypad.

Pros
- Unlocks via fingerprint, Bluetooth app, or physical key, offering three access methods.
- Features a built-in 400mAh rechargeable battery, eliminating the need for disposable AA batteries.
- Stores fingerprints locally, not in the cloud, for user privacy.
- Includes a 5-second auto-locking feature to ensure the door secures itself.
- Supports Privacy, Normal, and Passage modes, allowing flexible access control.
- Installation is straightforward, often completed in under 30 minutes with a screwdriver.
Cons
- App control is limited to Bluetooth range, requiring a separately purchased gateway for Wi-Fi access.
- The built-in 400mAh battery is not removable, meaning the entire knob must be charged in place.
- The locking mechanism can be noticeably louder than traditional door knobs.
- Only stores 20 fingerprints, which might be restrictive for larger households or shared spaces.
- Lacks an integrated keypad for code-based entry, relying solely on biometric, app, or key access.
Dimension Scores
The fingerprint sensor is reported to be fast and accurate, recognizing prints quickly.
Connectivity is limited to Bluetooth, requiring a separate gateway for Wi-Fi, which restricts remote access capabilities.
The app manages fingerprints, records, and modes, but its functionality is constrained by Bluetooth range and lacks broader smart home integrations without additional hardware.
Constructed from aluminum, it offers adequate durability for interior use, but lacks specific weather resistance ratings for outdoor applications.
Best For
- Bedroom doors where privacy and quick, keyless entry are desired.
- Interior office doors needing basic access control for a few users.
- Homes or apartments where a simple, budget-friendly smart lock is preferred over complex systems.
Not Recommended For
- Exterior doors requiring robust weather resistance and advanced security features.
- Users needing remote Wi-Fi control without purchasing an additional gateway.
- High-traffic areas or commercial settings requiring storage for many fingerprints or keypad access.
Watch Out For
- The built-in 400mAh battery is not user-replaceable, meaning if it degrades, the entire unit's lifespan is affected.
- Bluetooth-only connectivity means you can't unlock or manage the lock remotely when outside of Bluetooth range without buying a separate Wi-Fi gateway.
- Some users report the lock's operation is louder than expected for a door knob.
- Installation requires careful attention to the 'UP' signs and spindle bar orientation to ensure proper function.

What Buyers Say
Users frequently highlight the ease of installation, often completing it in under 30 minutes, and appreciate the convenience of the rechargeable battery, avoiding constant AA battery replacements. The fingerprint recognition is generally quick and reliable, making daily entry smooth. However, the Bluetooth-only app control means you're stuck within range unless you buy a separate Wi-Fi gateway, which is a common point of frustration. Some also note the lock's operational noise is louder than expected.
“Look, it's cheap, it works for my bedroom door, and I don't have to buy batteries every month, but man, I wish I could unlock it from downstairs without walking up there.”
Common Praise
- Installation is quick and simple, often taking less than 30 minutes.
- The built-in rechargeable battery is a significant convenience over disposable batteries.
- Fingerprint recognition is fast and accurate for quick entry.
- The auto-lock feature works reliably, securing the door after a set time.
- Physical keys provide a reliable backup entry method.
Common Complaints
- App control only works within Bluetooth range; Wi-Fi requires an extra purchase.
- The lock can be louder during operation compared to traditional knobs.
- The non-removable rechargeable battery raises concerns about long-term lifespan.
- Limited to storing only 20 fingerprints, which might not be enough for some users.
Ownership Tips
- The battery life, while rechargeable, can still feel short if the door is used frequently.
- The app, while functional for managing users and settings, isn't the most polished experience.
- You'll quickly realize the limitation of Bluetooth range if you want to check status or unlock from another room.
- The physical keys are a lifesaver when the battery runs low or the fingerprint sensor acts up.
Frequently Asked Questions
Does this lock work with Wi-Fi?
No, the lock connects via Bluetooth for app control. For Wi-Fi functionality, you need to purchase a separate gateway.
How many fingerprints can it store?
The lock can store up to 20 unique fingerprints.
Is the battery rechargeable?
Yes, it has a built-in 400mAh rechargeable battery that charges via a USB-A to Type-C cable. It takes 3 to 4 hours to fully charge.
Can I use physical keys if the battery dies?
Yes, the lock includes physical keys for manual unlocking, providing a backup in case of battery depletion.
Is it easy to install?
Installation is generally considered easy, often taking less than 30 minutes with basic tools. Instructions advise paying attention to the 'UP' markings during assembly.
Buying Guide
When looking at smart door knobs like this, you need to think about where it's going. For an interior door, the Bluetooth range is probably fine, but for a front door, you'll want Wi-Fi. Also, consider how many people need access; 20 fingerprints fills up faster than you think. Rechargeable batteries are a plus, but if it's built-in, that's the life of the lock.
Connectivity (Bluetooth vs. Wi-Fi)
Bluetooth means you have to be close to the door for the app to work, like being in the same room. Wi-Fi lets you control it from anywhere with internet, like checking if your front door is locked when you're at work.
Unlock Methods (Fingerprint, App, Key, Keypad)
More options mean more convenience. Fingerprint is fast, app is handy, keys are a backup. A keypad lets you give temporary codes to guests without needing their fingerprint or a physical key.
Battery Type (Rechargeable vs. Disposable AA)
Rechargeable means less waste and no need to buy batteries, but if it's built-in, the lock's lifespan is tied to that battery. Disposable AA batteries are easy to swap, but you'll be buying them regularly.
Alternatives
If this lock doesn't quite fit, search for smart door knobs with integrated Wi-Fi for remote access, or models that include a keypad for code-based entry and more fingerprint storage capacity.
