Buttons on driver door not working

[Bobroham]

Hey guys, 2012 128i convertible, I just got it and it has some problems.

1)
- Buttons on drivers door do not work. Windows, mirrors buttons don't work.
- Manual key lock/unlock does not work on drivers door from outside
- Drivers door buttons lights work. They light up.

2)
- Key fob wireless functions do not work even after changing battery. Buttons on fob do not work. Also ignition only works when key is plugged in. All wireless functions do not work.
- I can't lock my car at all so I have a real problem. Center lock button works but I can't lock the car while I'm inside.

3)
- I have a spare key fob from another 128i, is there any way to program it if my existing key fob wireless functions don't work?

I know there might be multiple problems here, but any suggestions?

right now I'm assuming my problems are fuse related.
I have spent the past 20 minutes reading my owners manual, googling and the fuse map in the glove box but I can't find what fuses to replace.

I believe I need the fuses that control
- key fob
- comfort access
- driver door cluster

any info on fuse numbers

Wiggle the black accordion bellows when the door is open. See IF the switches start working. Probably a broken wire is my guess.

Possibility also. I believe the warranty for this part is 10 years and 156k miles.

You really must join your local Trillium Chapter of BMWCCA and ask for their list of BMW recommended indy garages. Your situation is electrical/computer and likely difficult to diagnose.

Yeah, just looking at the symptoms quickly, it sounds like it could definitely be a fried FRM module.
