I have 2 matching key fobs that match my only existing original remote on my 1999 grand am se.It also has a factory installed ( when purchased new) VSC-3000 security system module.2 attempts with a scan tool were made,one by a GM dealership tech and another by an automotive locksmith,they could not program the key fobs.I'm not sure if it's an early model or late 1999.I have tried various methods on line that were for a 1999 and nothing seems to work.My original still works fine but would like to program the two matching ones as back up.Does anyone truly know how to program these 2 remotes.THANKS
