Hey there, i think you might need the "tech II scan tool" to program that remote. I know the 98-04 need it. At the dealer its like 75-100 bucks for that service, at least last time i heard. Maybe someone else on here knows...
The procedure is in the service manual. There is a connector in the trunk that needs to be grounded, and then the fob can be "learned". I'll need to get the complete procedure from the service manual and post it here, but I saved myself $75 that the dealer wanted to program mine by doing it myself. I also bought an extra remote for my '94 SLS on e-bay, and will be buying another one for my '95 D-Evil.
