The basic principle is: from the owner of the side of the weak radio waves, by the car antenna to receive the radio signals, by the electronic controller ECU to identify the signal code, and then by the system's actuator (motor or electromagnetic manager ring) to perform the start/stop action.

Functions of central control lock:


1. Central control: when the driver locks the door around him, the other doors are also locked. The driver can open/close the door through the door lock, open or close each door at the same time, or set to open the main driving door separately.  


2. Speed control: when the driving speed reaches a certain level, each door can be locked by itself to prevent passengers from mistakenly operating the door handle and causing the door to open.  


3, anti-lock control: when the driver opens the door, the lock insurance mechanism will lose its function, to prevent the key in the car, due to the wrong operation to open the insurance, then close the door and lock the car.


4. Child lock function: when a child is sitting in the back seat, open the child lock function, will not be able to open the door in the car, prevent the child to open the door by mistake to open the handle.
