If the fingerprint lock is not functioning due to a dead battery, you can replace the battery or recharge it using a charger, which will restore its normal functionality.
2、Main board damage/loss
If the main board is severely damaged due to prolonged use, we will need to request a replacement from the after-sales service. The typical warranty period for after-sales service is approximately one year.
3、Motor failure
If the issue is due to a motor malfunction, we need to repair or replace the entire motor. This repair typically falls outside the warranty, and the repair cost can be quite high. Therefore, if the motor is damaged, it is recommended to simply purchase a new one. A new fingerprint-based lock can be purchased for around $100.
