The central control lock is a switch button located next to the driver's seat. After pressing it, the door locks and glass of the other three doors can no longer be controlled separately, and they must be controlled by the driver alone. Otherwise, they can be controlled separately.

Central locking can improve the convenience of car use and driving safety. Modern cars are increasingly installing central locking in the car. The working principle is that electromagnetism is generated by electrification, and the electromagnetic attraction is used to control the locking and unlocking of the car door.
