Mercedes-Benz key battery model is CR02253V. Below is the relevant introduction to car remote keys: 1. Basic components of car remote keys: Consist of two parts - transmitter and receiver. 2. Transmitter: Composed of transmission switch, transmission antenna (keypad), integrated circuit, etc. Contains identification code storage circuit and amplitude modulation circuit, with a button-type lithium battery installed on the opposite side of the circuit. The transmission frequency is selected according to the radio standards of the country of use, and the transmission switch sends a signal each time it is pressed. 3. Receiver: After the transmitter sends the identification code via shortwave modulation, it is received by the car's shortwave antenna and enters the shortwave high-frequency amplification processor of the receiver's electronic control unit through a distributor for demodulation. The demodulated identification code is then compared; if it is the correct code, it is input into the control circuit to activate the actuator.
