The car does not have a remote control key can be fitted with a?

Car remote control key can be equipped. Configuration drawings are as follows:

The system is mainly composed of two parts: transmitter and receiver.

Transmitter: by the transmitter switch, transmitter antenna (keypad), integrated circuits and other components. Contained within the identification code storage circuit and amplitude modulation modulation circuit, and on the opposite side of the circuit is equipped with a snap-type lithium battery. The transmitter frequency is selected according to the radio standard of the country where it is used, and the transmitter switch sends out a signal every time the snap button is pressed.

Receiver: Transmitter using short-wave modulation issued by the identification code, through the car's short-wave antenna for reception, and the use of the distributor into the receiver electronic control unit of the short-wave high-frequency increase in the processor for demodulation, and the demodulator is compared to the identification code; if it is the correct code, it is input into the control circuit and make the actuator work.
