The operating principle of the car lock remote

The wireless remote control function of the car lock means that you can leave and lock the door from a long distance without inserting the key into the lock hole.

Basic principle of remote control(car lock): a weak radio wave is sent from the owner, the signal of the radio wave is received by the car antenna, the signal code is identified by the electronic controller ECU, and then the actuator (motor or electromagnetic coil) of the system performs the opening and locking action.
