You need to replace the electric door lock solenoid.The electrical part of the solenoid may be compromised and is not letting the solenoid arm retract or extend to lock/unlock your door.

SOURCE: 2002 BMW 325 - key locked in trunk

There are several suggestions out there on how to retrieve BMW keys from the trunk. Many of the ways I tried failed, and it takes 2 to 3 days to get a new key made up. In the coupe there is the center piece in the back seat that folds down. Then on the back wall there is material that will fold down that is held up with Velcro. Behind that you will find a rubber insulation that is mostly cut and looks like a door, but not all the way. Carefully cut the rubber to remove the piece. Now you will find a metal wall, but there is a large piece that is tack welded on. I got turned around and kicked it with the bottom of my foot and got 3 sides loose. Then a softball bat knocked the final side loose. Pull that out and trash it, the final barrier is the insulation that is held in place with plastic clips that can just be pushed down. After that you can a pretty large hole to work through and get the keys. Just put everything back in place other than the metal plate and you will never know anything was done.

I would follow their recommendation as I had the same problem with my car. They unhooked the power to that door and it was fine. The problem was a short in the wiring in the door that was causing the problem. So maybe get them to check the wiring in the door as well.

each door has there own door lock solenoid, the only thing they have in common is one fuse, either they all work or none of them will work. So I would say the door lock actuator inside the door has failed.
