Unlocking system problems

e90BTT · 09-28-2011, 05:29 PM

Hey guys well I've had my 07 BMW 335i for about a year now, I am having problems with the unlocking system, the unlocking button doesn't wanna unlock or lock my doors, the remote doest either. Could this be caused because I intalled the jb3? I've had it in for about 4 months now

Had a similar problem with my 2008 e91. From numerous threads I tracked it down to a blown fuse, specifically fuse #73, 15a. Replaced with a 20a and all locks are functional now.

Blown fuse and/or bad actuator in one of the doors tripping the system. I had both, the actuator shorted, blew the fuse and shut the system down. My seats and mirrors stopped working until it was replaced. I could only unlock the driver side door with the key, couldn't open any other door, even from inside. Easy fix, no problems since (over a year ago)

Blown fuse. I took mine in for it thinking it was the actuators but all it took was a 20 amp fuse and haven't had a problem since then.
