What are the reasons why the right rear door of a BMW cannot be opened?

[Roberto]

There are several reasons why the right rear door of a BMW cannot be opened: 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. Faulty lock cable: If this issue occurs, the door cannot be opened from inside the car because the faulty cable directly affects the lock mechanism. Deformed hinge or lock post: When the door is subjected to external force, it may cause deformation of the door hinge or lock post, which is also one of the reasons why the door cannot be opened. Faulty door limiter: When this problem occurs, opening the door becomes very difficult or impossible. The solution is to replace the door limiter with a new one, allowing the door to open and close smoothly.
