If your BMW E46 door locks are not working and your windows are malfunctioning this is the first thing you want to check, the GM5 module. Some additional signs the GM5 module is bad, are intermittent door locking ability and loss of remote locking function. Once you have repaired the module please see my video in the end on how to program the BMW E46 key after to regain remote locking function. Please feel free to ask questions in the comments section below, thanks a bunch.
