Why can't the front passenger door be opened from both inside and outside?

[LaAngela]

Doors that cannot be opened from both inside and outside are mostly due to faults in the locking mechanism components. Misalignment: Sometimes the door cannot be opened because it is misaligned. In this case, you can try pushing the door with your body from both inside and outside the car, or have someone assist you—one person pulling the door from the outside while another pushes it from the inside. Lower the door window: Remove the window wiper strips and trim, which will create a larger gap around the glass. Use a hook or similar tool to try pulling the cable or pushing the connection point between the cable and the locking mechanism to release it. Remove the door panel from inside the car: However, since the door cannot be opened, removing the panel can be quite difficult and may result in broken clips. After removing the trim, take off the sound insulation layer to gain better access to the locking mechanism. Try pulling the cable manually to see if it moves. If not, use a hammer and chisel or a drill to dismantle the locking mechanism. Generally, once the locking mechanism is disassembled, the door can be opened.
