What causes the Baojun 730 doors to lock automatically frequently?
3 Answers
Baojun 730's automatic door locking cannot be deactivated by the owner and requires a visit to an auto repair shop or 4S dealership for computer-based deactivation. The automatic door locking feature is designed for anti-theft purposes, enabling quick locking after driving to prevent door-pull robberies during traffic jams or at red lights, providing certain security benefits. Relevant information about the automatic locking function is as follows: Introduction: The automatic door locking function of motor vehicles activates when the vehicle reaches a certain speed, automatically locking all doors. Purpose: It prevents children from opening rear doors during rides, avoiding unnecessary traffic accidents. It also deters potential door-pull robberies against vehicle owners while waiting at red lights.
When I first started driving, I also frequently encountered the issue of the Baojun 730 doors automatically locking themselves. Later, I summarized a few possible reasons. First, the internal switch of the door lock mechanism might have poor contact due to accumulated dust or mechanical wear over time, causing it to misjudge the unlocking state. Second, the remote key might have insufficient battery or signal interference, especially when near strong magnetic fields. Third, there might be minor software glitches in the Body Control Module (BCM), which occur more frequently during rainy days or significant temperature changes. I recommend trying simple solutions first: replace the remote battery with a new one, ensuring the key battery has at least 30% charge; then check the car settings to turn off the automatic locking feature, which can be adjusted in the menu. If the problem persists, it might be due to loose or corroded wiring harness connectors—have a friend check the circuit continuity with a multimeter. Regularly cleaning the door lock slots can prevent this issue, as uncontrolled locking could trap people or items inside the car, which is quite dangerous. Safety first—don’t delay necessary repairs.
My Baojun 730 has encountered this issue several times. I think most of the time it's due to remote control failure or aging lock cylinders. The doors keep locking automatically, especially while driving or parked, which is really annoying. I suspect the reasons include loose springs inside the lock mechanism, temperature-sensitive electronic components that expand and get stuck in high temperatures; another common issue is poor contact in the door switch connectors, where rainwater seeps in causing short circuits and false triggers. I've tried DIY fixes: disconnecting the battery cables to reset the system for a minute or two works quite well; or cleaning the door handle sensor area with a brush to remove dust and grease. I remember the 4S shop technicians reminding me to maintain the locking system regularly—replacing a new lock assembly only costs a few hundred yuan. If left unfixed, sudden door locking while driving could easily cause accidents; I was almost locked out of my car once. Many Baojun owners in the car club have shared similar experiences, all saying it's a minor issue that's best fixed promptly.
