I just got my car back after replacing the bumper. When I remove the key, all lights on the dash stay on, the headlights stay on and the brake lights stay on. The key fob stopped working and the button to lock/unlock inside the car also stopped working. Here is a short video. https://youtu.be/hzSzAJZ3gFY
I tried reprogramming the key, no luck. Also disconnected the battery overnight as other threads I read suggested, also no luck. Any help is apprecitated.
Car is a 2005 E46 M3 if that makes any difference.
Did you scan for BMW codes?
If the headlight module has failed, there should be a code.
The comfort module would be scanned as
If the ignition switch is bad, there may be a code also.
If a shop did the work, then they should be acountable.
