What are the reasons for the sudden inability to open the passenger door from both inside and outside?
2 Answers
The reasons for the sudden inability to open the passenger door from both inside and outside are: 1. The remote key battery is dead, preventing the door from opening; 2. Remote control malfunction; 3. Fault in the door lock mechanism itself, or failure of the door lock cable; 4. Deformation of the door hinge and lock pillar due to external force applied to the door. Solutions for the door not opening include: 1. Using a spare key; 2. Contacting a qualified and professional locksmith; 3. Calling the after-sales rescue hotline; 4. Using tape to pull the window glass open forcibly; 5. Removing the door seal with a sharp object and using a wire to press the unlock button through the gap.
I've encountered this issue before, and it really stressed me out that time. When neither the inside nor outside of the passenger door can be opened, it's most likely a problem with the door lock mechanism. It could be a broken or jammed spring in the lock assembly, or the cable might have come unhooked, which is also a common cause. For electronic locks, you also need to consider issues with the central control module or wiring. I've tried fixing it myself—first by forcefully slapping the lower part of the door, as sometimes the vibration can reset stuck components. Then, repeatedly pressing the remote unlock button a dozen or so times might wake up the electronic system. If that doesn’t work, you can crouch down and check the door gap for any foreign objects that might be jamming the lock, though this is rare. In the end, I had to take it to the repair shop to remove the door panel. The mechanic said it's best not to yank hard on such faults, as it can easily break the door handle. Oh, and if the door has been hit, even a minor scratch could deform the lock body and cause it to jam.
