What is the reason why the BMW door cannot be opened from the inside?

[MarleyMarie]

It is the child lock that is engaged. When the child lock is activated, passengers inside the car cannot open the door from the inside. This is to prevent children from opening the door by themselves while the car is moving, which could lead to safety accidents. To deactivate the child lock: There is a switchable button on the edge of the rear door. Follow the instructions to toggle it for activating or deactivating the child lock. To activate the child lock: The child safety lock, also known as the door lock child safety mechanism, is located on the rear door lock. After opening the rear door, there is a small lever (safety mechanism) below the door lock. Move the lever toward the end with the child icon, then close the door. Now, the door cannot be opened from the inside and can only be opened from the outside.
