About this product: Rechargeable and Humanized Design The fingerprint furniture lock features a rechargeable design with a USB charging interface. The USB port is located beneath the fingerprint sensor for convenient emergency charging. With low power consumption, it can last approximately 180 days on a full charge. Supports registration of up to 40 fingerprints and allows multiple users to manage access. Quick Unlock This fingerprint security lock uses professional biometric technology with 360-degree angle recognition, enabling fast unlocking in 0.5 seconds. Designed to avoid sensitivity issues caused by door thickness, unlike RFID locks. (Note: The applicable hole diameter should be no less than 15mm.) Easy to Install and Set Up The lock includes an administrator function that requires verification of the administrator fingerprint before adding new fingerprints or deleting all registered fingerprints.

Unlock Operation - When a correct fingerprint is detected, the green light turns on, indicating successful unlock. - Incorrect fingerprint input results in a red light and unlock failure. Locking Operation - Automatically locks 4 seconds after unlocking, once the door is closed. Fingerprint Registration 1) Press and hold the setup button until the blue light turns on, then release. 2) Place your finger on the sensor and keep it steady until the green light stays on. Remove your finger and repeat the process four more times for a total of five registrations. Upon successful registration, the green LED will illuminate for one second. (Note: If the red light appears during registration, repeat the process with a different finger.) - Up to 40 fingerprints can be registered. - When 40 fingerprints are already stored, attempting to add another will cause the fingerprint light to turn red and return to standby mode. All fingerprints must be cleared before new ones can be added. - The first three registered fingerprints are set as administrator fingerprints. If no fingerprints are registered, the lock can be opened by any user. Battery Replacement - When the battery is too low to operate the lock, emergency power can be supplied via the USB interface. Replace the battery after unlocking. Deleting All Fingerprints - Press and hold the reset button for 4 seconds until the red light turns on. This clears all registered fingerprints.
