The battery model for BYD F3 key is CR1632, and the spare key battery model is CR2025. Owners can use a flat-head screwdriver to turn clockwise at the bottom of the remote control, pry open the remote cover, and then see the battery model. The remote key utilizes the wireless remote function of the central locking system, allowing doors to be opened and locked from a distance without inserting the key into the lock. The remote key mainly consists of two parts: the transmitter and the receiver. Transmitter: Composed of a transmission switch, transmission antenna (keypad), integrated circuit, etc., it includes an identification code storage circuit and an 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. Receiver: After the transmitter sends the identification code using shortwave modulation, it is received by the car's shortwave antenna, then enters the shortwave high-frequency amplification processor of the receiver's electronic control unit via a distributor for demodulation. The demodulated identification code is compared, and if it is correct, it is input into the control circuit to activate the actuator.
