The reasons why the right rear door of the BMW 5 Series cannot be opened from both inside and outside: Child lock is in the on state: Generally, the rear doors of vehicles have a child lock, which is located on the side of the door with a child symbol. If it is accidentally turned on and the door is closed directly, the door cannot be opened. Failure of the door lock block cable: If the cable fails, it directly affects the lock block and prevents it from opening. In this case, the only solution is to replace the door lock block cable to restore the door's functionality. Deformation of the door hinge or lock post: When the door is subjected to a certain 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. In such a situation, the only solution is to dismantle both the door and the hinge, and then replace them with new hinges and lock posts to ensure the door can open and close normally.
Last time I encountered a situation where both the inside and outside of the right rear door of a BMW 5 Series couldn't open, which seems quite common. It might be the child lock function being accidentally activated - this is very common with rear doors. BMW's design requires manual closing or button adjustment. If the switch is broken, such as internal jamming or corrosion, the door naturally won't move. I've experienced winter ice blockage issues before - in northern cold weather, ice forms in door gaps and blocks the mechanism, requiring warm water to slowly melt it. There are also wiring problems, like aged wires short-circuiting or fuses blowing, preventing current from reaching the lock cylinder. BMW's electronic lock modules sometimes act up and need restarting or system updates. You can first check the remote key functions yourself, and if that doesn't work, quickly find a professional shop for repairs - safety first, don't delay. As the old saying goes, fixing car doors can be more troublesome than fixing engines, but timely handling can save big money.
