Q: Key fob won't unlock doors

asked by on

When I press the key fob, I can't open the doors from the outside

Hi. If your FOB is not unlocking the doors, then the battery in the FOB may be bad. I would either replace the battery or try a spare FOB if you have one. If the battery does not help, then the FOB itself may be bad. It can also be a failure in the receiver module for the door locks. The only way to verify if this is functioning is with a computer scan tool that can communicate with that module. I would start with the battery and see if that takes care of it. If the battery does not help, then I would recommend the assistance of a certified mechanic, like one from YourMechanic, to inspect for other electrical issues.

Q: My door does not lock or unlock. Would I need to replace a fuse or buy a new key?

I believe the door lock actuator has failed, not a fuse or key. BMW door lock actuators (part electric, part mechanical) have what is essentially a two-stage lock, and can fail and become "double-locked". Sometimes, exercising the "unlock/lock/unlock" cycle multiple...
