The battery has power, but the door lock screen is not lit

Possible reasons are as follows: 1) Check if the battery compartment is short-circuited; 2) Disassemble the lock to check if the door lock cable is squeezed, broken, the connector is loose, or the pin is deformed; 3) If the battery is not installed on the door and connected to the cable, test whether the screen is not lit.
