What is the reason why the Wuling Hongguang S remote control cannot lock the door?
2 Answers
Wuling Hongguang S remote control cannot lock the door because the remote control lock is malfunctioning or the antenna of the remote transmitter in the car is aging, which causes the remote key to not work. The basic components of the remote key are as follows: 1. Transmitter: It consists 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 the transmission switch button sends a signal once per press; 2. Receiver: After the transmitter sends the identification code using shortwave modulation, it is received by the car's shortwave antenna, and then 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.
Remote locking failure is quite common on the Wuling Hongguang S, usually caused by accumulated minor issues. Low battery in the key fob is the most frequent culprit – replacing it once solved my problem. Additionally, dust buildup on door sensors can sometimes jam them, falsely indicating an unclosed door and preventing locking. Check if all doors are fully shut, especially the rear hatch which tends to loosen. Signal interference is another possibility, such as nearby cell towers or electronic devices disrupting the key's remote signal. Lastly, the key itself may be moisture-damaged, or the locking mechanism could be rusted/jammed. In such cases, try using the manual key temporarily or test with fresh batteries first. If that fails, visit a repair shop for wiring/control module inspection. Regular maintenance like keeping keys dry and cleaning sensors periodically can prevent many issues.
