Have a 2006 Lucerne CXS with the 4.6. Had the alternator fail while driving, which created an internal dead-short inside the alternator. After replacing the alternator I found that the keyless entry/remote start/truck release no longer work with the key fobs, and I am unable to re-program any key fobs, if I go through the DIC to "PRESS TO RELEARN REMOTE KEY" it just flashes a blank screen for a second and then display "PRESS TO RELEARN REMOTE KEY" again. I have tried pulling every fuse I can think of, but nothing seems to work. I have talked with my uncle at a GM dealer and he said the techs don't have any idea what it could be without looking at it. At this point I am assuming it is the BCM? Which would need to be programmed at the dealer? Any one else have any ideas what it could be?
