AI Verdict
This is a budget 4-in-1 fingerprint door knob for interior wooden doors 1.18"-1.97" thick, offering keyless entry with fingerprint, keypad, key, and IC card.
This lock is a situational fit because its 4-in-1 access methods and quick fingerprint recognition are appealing for interior privacy doors, but the strict door thickness requirement (1.18"-1.97") and lack of explicit weather resistance limit its use. The critical first-step setup for an administrator fingerprint also requires careful attention.
If you need a lock for exterior doors or require smart home integration, look for models with an IP weather rating and Wi-Fi/Bluetooth connectivity for app control.

Frequently Asked Questions
Does this lock connect to Wi-Fi or a smart home system?
No, the product specifications do not mention Wi-Fi, Bluetooth, or any smart home integration like Alexa or Google Home. It functions as a standalone biometric and keypad lock.
Can I use this lock on an outdoor gate or front door?
The product description does not specify any weather resistance or outdoor rating. Given it's a privacy lock and lacks such details, it's best suited for interior doors to avoid potential damage from elements.
What happens if the batteries die?
If the batteries run out, you can use one of the two mechanical keys provided to unlock the door. There's also a USB port for emergency power using an external power bank, allowing you to use the electronic functions temporarily.
How many fingerprints and passwords can it store?
This lock can store up to 100 unique fingerprints and 50 different passwords, accommodating multiple users for bedrooms, offices, or guest access.
Is installation difficult, and do I need special tools?
Installation is designed to be easy, requiring no drilling or wiring. It fits wooden doors between 1.18" and 1.97" thick and comes with video tutorials and all necessary tools.
What is the 'Important First-Step Setup' mentioned?
Before its first use, you must register an administrator fingerprint. If you skip this step, any fingerprint will be able to unlock the door, compromising security.
Buying Guide
When you're looking at a fingerprint door lock, you need to think about where it's going. Is it for your bedroom, an office, or maybe a rental unit? The key is matching the lock's features to your actual needs. Don't just assume it'll work everywhere or connect to your smart home unless it explicitly says so. Also, consider who will be using it and how many access methods they'll need.
4-IN-1 Smart Lock (Fingerprint + Password + 2 Mechanical Keys + 4 IC Card)
This means you have multiple ways to get in, which is handy. Fingerprint is quick, a code is good for guests, and keys are your backup if everything else fails. IC cards are like little key fobs, useful for quick access without remembering a code.
Door Thickness (1.18"-1.97")
This is crucial because if your door isn't within this range, the lock simply won't fit. Measure your door's thickness before buying, just like you'd measure a window for blinds.
Upgrade Fingerprint Sensor & 0.5S Recognizing
A fast sensor means you won't be standing there for ages trying to get the door open. 0.5 seconds is pretty quick, like tapping your phone's fingerprint reader.
Alternatives
If this lock doesn't fit your door or you need remote access, look for models that specify a wider door thickness range, an IP weather rating for outdoor use, or explicit Wi-Fi/Bluetooth connectivity for app control.
