Why can't the BMW 5 Series door be opened from the inside but can be opened from the outside?

If the BMW 5 Series door cannot be opened from the inside but can be opened from the outside, it may be because the child lock is activated. Simply turn it off to resolve the issue. Introduction to the child lock: The car child lock, also known as the door lock child safety feature, is located on the rear door lock. When the rear door is opened, there is a small lever (safety mechanism) below the door lock. By sliding it toward the end with the child icon and then closing the door, the door can no longer be opened from the inside but only from the outside. Function of the child lock: Its purpose is to prevent active and unaware children from opening the door while the car is in motion when seated in the rear, thereby avoiding danger. In this case, the door can only be opened by an adult from the outside after the car is parked.
I had the same issue with my BMW 5 Series before—the door wouldn't open from the inside but unlocked with a press from the outside, which really startled me. The most common cause is the child safety lock being activated. There's a small switch on the edge of the door, which you might have accidentally bumped or a child playing with it could have flipped. BMW designed this for safety to prevent kids from opening the door while driving, but it's easy to forget about in daily use. Another possibility is that the internal linkage of the door handle has come loose or is damaged, especially in older models, where pulling the handle doesn't transfer force to the lock mechanism. It could also be that the door lock itself is jammed, like from ice in winter or debris, making it unresponsive even when pulled hard from inside. First, check the child lock switch and try turning it off. If that doesn’t work, inspect whether the handle feels loose—these are things you can do yourself. If the issue persists, the locking mechanism might be broken, and it’s best to have a professional check the electronic system or parts for faults. Don’t force it open to avoid injuring your hand. Safety first—get it fixed for peace of mind.
