Fingerprint locks are being fully popularized. Because fingerprint locks have only become popular in recent years, many consumers don’t know much about fingerprint locks, but because of the strong security and convenience of fingerprint locks, many consumers still Choose to install the fingerprint lock to use, but many people will encounter some minor problems when using the fingerprint lock. Let's follow the Fingerprint ZigBee lock editor to have a simple understanding!
1. The fingerprint verification is successful, but the door lock cannot be opened normally
After the electronic unlock verification such as fingerprint or password is successful, the door lock cannot be opened normally, there are three main situations:
1. It is usually caused by the spring of the square steel falling off. Just disassemble and reinstall. If you don't know how to install, you can consult the merchant's after-sales remote guidance, or contact the installer for help.

2. The battery is not enough to drive the motor to work, so the door lock cannot be opened. Replace the battery and try to see if it can be used normally.
3. The motor cannot be opened normally after the fingerprint verification is successful due to the damage of the motor.
2. What to do if the fingerprint lock is out of power
If you really forget to replace the battery, you find that the fingerprint lock is out of power when you return home. You can use the key to unlock it. If you don’t have a key, the fingerprint lock generally has a USB charging port, and you can use a power bank to charge the fingerprint lock, etc. After opening the fingerprint lock, replace the battery immediately, because dry batteries cannot be recharged.
The above is the editor of Fingerprint ZigBee lock: a brief introduction to some problems in the use of fingerprint lock.
