What are the reasons for BMW door locks not popping up?

Reasons for BMW door lock switches not popping up: 1. Damaged components: The lock cylinder drive rod has come off; door lock latch malfunction, internal spring of the latch is broken or stuck and not flexible. 2. Misalignment of the latch position: The door latch not springing back may be due to misalignment of the latch position, requiring adjustment of the positional relationship between the latch and the loop; tools such as a screwdriver can be used to gently adjust the latch, then close the door to test until it fits properly. 3. Rust on the lock hook: Rust on the lock hook can also cause the door latch not to spring back. You can purchase a bottle of rust remover or grease for rust removal, evenly apply it on the inner lock hook and latch of the door, then repeatedly open and close the door to ensure even lubrication; additionally, if the inner lock hook is tilted, the entire door needs to be adjusted.

I've encountered the issue of BMW door locks not popping up several times, usually due to the lock cylinder or internal mechanism getting stuck. Accumulation of dust, dirt, or old grease inside the lock can prevent it from springing back, especially after rain or snow when moisture seeps in and causes rust, making it worse. BMW door locks have a relatively precise structure, and wear on small components or spring breakage can also lead to this problem. I tried lubricating it with WD-40 spray myself, which provided a temporary fix, but if it happens repeatedly, the entire locking system needs to be inspected. Sometimes, if the door has been hit or forcibly closed, the lock position may shift, making it harder to pop up. For safety, I recommend not forcing the door open. First, check for any signs of impact on the door, then consider a thorough cleaning or part replacement. Ignoring the issue long-term can worsen the problem and affect driving convenience. It's best to have a professional shop disassemble and repair the lock assembly, with costs typically around a few hundred yuan.
