What is the reason why the central control lock of the Lavida's left front door cannot be used?

[NoraLynn]

If the central control lock of the Lavida's left front door cannot be used, it may be due to a fault in the car's electronic circuit. Introduction to Central Control Lock: The full name of the central control lock is Central Control Door Lock, which is an automotive accessory. Using this lock, you can remotely open and lock the door without inserting the key into the lock hole. It consists of a door lock switch, an actuator, and a controller. Door Lock Actuator: The central control lock actuator is used to execute the driver's instructions to lock or unlock the door. There are three driving methods for door lock actuators: electromagnetic, DC motor, and permanent magnet motor. Their structures all change the polarity to reverse the movement direction to perform the locking or unlocking action.
