What is the reason for the Nissan Sylphy remote control not responding when pressed?
1 Answers
Nissan Sylphy remote key failure is usually caused by the battery running low. You can split the remote key along the middle seam and replace it with a new battery. If that doesn't work, try re-matching the remote. Since smart keys use low-intensity radio waves, they may not function properly in the presence of magnetic interference. Frequently placing the smart car key and mobile phone together will inevitably cause the smart car key to malfunction. The basic components of a remote key are as follows: 1. Transmitter: Composed of a transmission switch, transmission antenna, integrated circuit, etc., containing an identification code storage circuit and an amplitude modulation circuit, with a button-type lithium battery on the opposite side of the circuit. The transmission frequency uses radio waves, and pressing the transmission switch button once sends a signal. 2. Receiver: After the transmitter sends the identification code using 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, where it is compared with the demodulator's identification code.
