What Causes the Inner Door Handle to Fail in Opening the Door?

[LaLilah]

Here are the specific reasons why the inner door handle fails to open the door: 1. The central locking system is activated: When the door cannot be opened, you can first use the car key to unlock and then lock it, repeating this twice. Locate the central lock button on the left front door trim panel in the driver's compartment and press the unlock button. 2. The child lock is engaged: Most vehicle rear doors are equipped with a child lock. Use a flathead screwdriver to turn the child lock to the off position. 3. The door lock cable is malfunctioning: A faulty cable directly affects the lock mechanism's ability to open. 4. The door hinge or lock post is deformed: After the door is subjected to external force, the hinge or lock post may become deformed, which is another reason the door won't open. In this case, the door and hinge must be disassembled together and replaced with new hinges and lock posts to restore normal door operation.
