Inserting the car key into the keyhole and turning the key is equivalent to closing the switch and the car starts. Connect the circuit diagram in the following figure to control the start of the car

Attracting the armature downward turns on the contact switch on the right side of the solenoid; further turns on the circuit where the motor is located, and the car starts. Therefore, the coil is connected in series with the key switch and the power supply, and the motor is connected in series with the power supply and the contact switch.

The signal contains the corresponding command information, and the antenna at the automobile end receives the radio wave signal, which is certified by the BCM of the body control module, and there is an actuator to realize the action of unlocking/closing the lock.

Main Functions:

Automotive remote control can not only control the opening and closing of the doors, but also control the windows as well as the trunk, which are more commonly used in normal daily life. When you want to speed up the air circulation in the car, so as to ventilate or remove the odor, you can pick up the remote control and roll down the windows.
