Hey bigjohnson,

I think my 2003 X5 is suffering same as yours. I have a door lock/unlock issue with the following symptoms:

*remote keys only works to open trunk, but not on doors or alarm, although, still can use key to lock/unlock manually via keyhole, start engine, and truck runs fine;
*main cabin lights are out;
*center console lock/unlock button not responding;
*fuel lid locks/unlocks with doors;
*no burnt fuses in trunk area.

Are your symptoms the same? Did replacing the module (ZKE/BCM/GM...some of the name for the module I have seen this far) fix the problem?

Thanks,
