What if the fingerprint lock is dead and can't be opened?

The fingerprint lock is dead and can't be opened. solution

1, mechanically unlocked

In order to prevent the battery from running out, the common fingerprint locks on the market reserve a keyhole for the lock body, which can be opened with a special key. You can directly open the back cover, replace the alkaline dry battery and resume normal use. The common fingerprint lock uses 8 5th batteries, and the service time is about 1 year.

2. Temporary charging

If the fingerprint lock is dead, just connect the charging treasure to the fingerprint lock for power supply. The common charging interface of fingerprint lock is MicroUSB interface, which used to be the charging port of Android phone. Now many smartphones have been upgraded to USB-typeC interface. I believe that the charging interface of fingerprint lock will be upgraded in the near future.

3. Professional maintenance

If you can't buy a 9V battery and don't have a charging treasure, you can ask a professional to unlock it. The cause of circuit failure needs professional maintenance, generally, the circuit board is burnt out, short circuit, solder joint falls off, poor contact and so on. You need to call the corresponding brand after-sales phone to solve the problem!
