Why Can't the Front Door of Baojun 730 Be Opened?
3 Answers
Baojun 730 front door cannot be opened for the following reasons: Child lock is engaged: When closing the door, always check if the child lock is disengaged. If the door cannot be opened, use a flathead screwdriver to turn the child lock to the off position. Lock cable failure: When this occurs, the door cannot be opened from inside the vehicle because the malfunctioning cable directly affects the lock mechanism's operation. Hinge lock post deformation: If the door is subjected to external force, it may cause deformation of the door hinge and lock post, which is another reason the door cannot be opened. Door limiter malfunction: When this issue arises, opening the door becomes extremely difficult or impossible. The solution is to replace the door limiter with a new one to restore smooth door operation.
As someone who has been repairing cars for many years, I often see issues with the front door of the Baojun 730 not opening. The usual causes are either the door lock mechanism getting stuck or the child safety lock being accidentally activated. First, you need to determine whether it's just one door that won't open or if all doors are affected. If it's only the front door, it's likely due to dust buildup in the lock cylinder causing stiffness, or the child lock button on the door side being accidentally pressed and unable to reset. Another possibility is that the key battery is dead, affecting the remote function, or the lock hole being frozen in winter—don't force it and risk damaging the door handle. I recommend gently shaking the door handle to check for looseness, then verifying the child lock is properly disengaged. If that doesn't work, try applying a hot towel to the lock hole. If all else fails, head to a 4S shop for a professional inspection—don't attempt to dismantle the door yourself and risk damaging the wiring. Safety first, as a door that won't open unexpectedly can delay trips and increase risks. Regularly spraying some lubricant on the lock can prevent this issue, saving you from being stranded halfway.
I've been driving my Baojun 730 for a while, and one time the front door just wouldn't open no matter what—really frustrating. Later, I found out the child lock was accidentally turned to the locked position—that button is right on the edge of the door seam and super easy to bump into. But that's not the only possible cause; it could also be due to the lock mechanism aging and the spring failing, or the door handle linkage rod coming loose and not pulling properly. Don’t forget to check the key fob signal—if the battery is weak, the remote won’t work, and you’ll need to replace it. For routine maintenance, don’t overlook lubricating the lock mechanism, and when washing the car, tell the car washer not to spray water directly into the keyhole to avoid clogging it. I recommend flipping through the manual to find the child lock operation steps—it’s a simple adjustment. If that doesn’t work, schedule a free inspection at the 4S shop. Don’t just make do when it comes to safe driving, or you might get stuck in an emergency. Get into the habit of giving the door a light pull test before locking it—it’ll save you a lot of trouble.
