What are the reasons for a car door handle being difficult to open?

[LaJuliette]

Here are the specific reasons why a car door handle may be difficult to open: 1. The central locking system is engaged: When the door cannot be opened, you can use the car key to unlock and then lock it again. Locate the central locking button on the left front door trim panel of the driver's side and press the unlock button. 2. The child lock is engaged: Most rear doors of vehicles have a child lock. Use a flat-head screwdriver to turn the child lock to the off position. 3. The door lock cable is malfunctioning: A malfunctioning cable directly affects the lock mechanism, making it difficult to open. 4. Deformation of the door hinge or lock post: When the door is subjected to external force, it may cause the door hinge or lock post to deform, which is another reason why the door cannot be opened. In this case, the door and hinge must be disassembled together and replaced with new hinges and lock posts to restore normal door operation.
