Are all GM key fobs created equal? My wife'* 99 Jimmy looks almost identical to my 01 Bonne fob. In order to tell them apart I'd like to get an 01 GP fob. They shaped a little different. Nobody really makes universal fob that would control more than one vehicle, do they?

you need to have the same FCC ID on the Back....if it dosent match that number, it wont work

Grr, I'm guessing there'* a different FCC code for each model car. It'* different from the Bonneville to the wife'* Jimmy....
