What are the reasons why the driver's door of a BMW 730 cannot be opened?

[MacFernando]

There are several reasons why the driver's door of a BMW 730 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 disengaged position. Lock cable malfunction: When this issue occurs, the door cannot be opened from inside the car because the malfunctioning cable directly affects the lock mechanism. Hinge lock post deformation: When the door is subjected to external force, it may cause deformation of the door hinge and lock post, which is also one of the reasons why the door cannot be opened. Door limiter malfunction: When this problem occurs, it becomes very difficult to open the door, or it may not open at all. The solution is to replace the door limiter with a new one, allowing the door to open and close smoothly.
