What is the reason for the central lock failure and the car not starting?
2 Answers
The reasons for the central lock failure and the car not starting are: 1. Whether there is a signal interference source around the vehicle; 2. Wireless signal failure; 3. Insufficient battery power. The solutions are: 1. Check the vehicle and find that a wireless MP3 is installed in the cigarette lighter; 2. Replace the battery or go to a repair point for maintenance. The central lock is a system where when the driver locks the door next to them, all other doors are also locked simultaneously. The driver can use the door lock switch to open all doors at once or open a single door individually. The principle of the central lock is that the owner emits a weak radio wave, which is received by the car antenna. The electronic control unit (ECU) then identifies the signal code, and the system's actuator performs the action of unlocking or locking.
I've been driving for over a decade and have encountered situations where the central locking system failed while the car wouldn't start. This is usually due to a blown fuse or extremely low battery voltage. The central locking and ignition system share the same power supply - if a fuse blows, the locks stop working and the car won't start. Last winter this happened to my car when the aging battery discharged quickly. The door locks didn't respond to the remote, dashboard lights were dim, and the engine just clicked without starting when I turned the key. I had to use the mechanical key to open the door but eventually needed to call a tow truck. My advice is to first check the fuse box in the engine compartment and replace any blown fuses. For battery issues, measure the voltage or try charging it. Otherwise, seek professional repair. Preventive maintenance can avoid such troubles, especially since car batteries typically need inspection/replacement every 3-4 years.
