I have a 2006 M roadster. Recently I tried to unlock the drivers side door using the remote. It unlocked then immediately relocked. I tried using the key in the door and had the same response. The passenger side door unlocks correctly. Any suggestions?
I would start by checking the lock tumbler on the drivers door I have seen these send incorrect locking signal to the vehicle.
Hello, Sounds like the beginning of the well known GM5 module failure. I've had this issue. Google it. It's a quick and easy repair. Good luck.
