What is the reason why the rear door of a BMW cannot be opened?

[Nellie]

BMW rear door cannot be opened because the child safety lock is engaged. When the central door lock is activated, you can open the door by using the switch on the outside of the door. Child Safety Lock: This feature is designed for the rear doors of the vehicle to prevent the danger of opening the door from inside while the vehicle is in motion. When this feature is active, even if the electronic central door lock is unlocked, the door remains locked. To open the rear door, you must use the switch on the outside of the door while the central door lock is activated. Function of the Safety Lock: The car child safety lock, also known as the door lock child safety mechanism, is located on the rear door lock. When you open the rear door, there is a small lever (safety mechanism) below the lock. Move the lever toward the end with the child icon, then close the door. At this point, the door cannot be opened from the inside, but can only be opened from the outside. Its purpose is to prevent active and unaware children from opening the door while the car is moving, thereby avoiding danger. In this case, the door can only be opened from the outside by an adult after the car has stopped.
