How Does Central Locking Work?
Answer
These is an electromechanical system that can be operated manually or by a remote, keyless entry system. The door locks are open and closed using motors. The motor is normally connected with one side permanently to the 12 Volt supply the relays connect the other side to the ground. The transmitter of the remote control can produce unique coded infrared (IR) or radio frequency (RF) signals to the car's ECM (Electronic Control Module) by pressing the different buttons on it. The ECM is the signal processing unit. It decides the amount of polarity of power to be supplied to different solenoid or motors of actuators upon receiving the IR or RF signals from remote controller.
