1 Answers
Nissan Sylphy car key uses a 3V CR2025 button battery. The remote key utilizes the wireless remote control function of the central locking system, allowing you to lock and unlock the doors from a distance without inserting the key into the lock. Remote keys can be categorized into three types based on their operation methods: active mode, passive mode, and coil induction mode. The system mainly consists of two parts: the transmitter and the receiver: 1. Transmitter: Composed of the 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. 2. Receiver: After the transmitter sends the identification code via shortwave modulation, it is received by the car's shortwave antenna and processed by the distributor into the receiver's electronic control unit for demodulation through the shortwave high-frequency amplification processor. The demodulated identification code is then compared; if it matches the correct code, it is input into the control circuit to activate the actuator.
