What to Do When the Rear Door Lock of Baojun 730 Malfunctions?

[OElias]

If the rear door of a Baojun 730 cannot be locked, the primary checks should include ensuring the rear door, trunk, and front hood are properly closed. Additionally, inspect each lock mechanism and the control circuit for any open or short circuits. Generally, a door that won't lock is due to issues with the door lock mechanism, the locking actuator, or circuit faults. It is advisable to have it checked at a repair shop. Reasons why a car door won't lock: 1. Remote Key: The remote lock may fail to function due to a malfunctioning remote lock or aging of the car's remote transmitter antenna, among other factors. In such cases, the spare mechanical key can be used to lock the door. 2. Magnetic Signal Interference: Since smart keys use low-intensity radio waves, they may not work properly under magnetic interference. 3. Door Jammer: If the car frequently fails to lock via remote in a particular location, the owner should be wary of a door jammer. Some criminals use a radio signal jammer that emits electromagnetic waves at the same frequency as the lock signal, thereby blocking the electronic code of the car's central locking system and temporarily disabling it.
