What Causes the Baojun 730 to Fail to Lock?
2 Answers
Baojun 730's failure to lock can be attributed to an aging remote transmitter, magnetic field interference, or door jammers. Below are the detailed explanations: Aging Remote Transmitter: If you are using the remote key to lock the door, it is highly likely that the remote lock is malfunctioning or the antenna of the car's remote transmitter has aged, causing the remote key to fail. In this case, you can use the spare mechanical key to lock the car. Magnetic Field Interference: Another possibility is strong magnetic field interference around the car. Since smart keys use low-intensity radio waves, they cannot function properly under magnetic interference. Door Jammers: If the car frequently fails to lock remotely in a particular location, the owner should be wary of door jammers. Some criminals use radio signal blockers that emit electromagnetic waves at the same frequency as the lock signal, thereby disrupting the car's central locking system's electronic code and temporarily disabling it.
I've been driving for over ten years and often encounter this issue. It could be due to mechanical jamming of the door lock, a door not being properly closed, or the key fob battery running low, causing the signal to fail and the car not responding. Electronic system malfunctions are also possible, such as a faulty central control module or the trunk or hood not being properly closed, triggering a safety mechanism that prevents locking. If the buttons on the remote key get wet or are dropped, they may also stop working. When checking, first ensure all doors are tightly closed, then try manually locking the car to see if it works. If that doesn't help, replace the key fob battery or consult a professional technician to scan the system for error codes. In daily use, avoid exposing the key to humid environments to prevent short circuits, as repairs can cost anywhere from tens to hundreds of dollars.
