One, does the fingerprint lock have a key?
The fingerprint lock has a key, and the door can also be opened with a regular key.
Fingerprint locks are not only convenient but also equipped with mechanical locking mechanisms for security. The National Public Security Bureau has mandated that all door locks, including fingerprint locks, password locks, hotel access locks, and key-operated locks, must have a mechanical key as a backup in case of power failure or malfunction.
Two. How to open the door using a key on a fingerprint lock.
First, locate the keyhole of the fingerprint lock. In normal operation, the key should be inserted into the keyhole at the bottom or within the sliding mechanism. Next, align the key with the lock's opening and insert it parallel to the opening. Finally, gently rotate the key clockwise. However, it is generally recommended to unlock fingerprint locks using the six-digit code or by placing your finger on the sensor, rather than using a key.
