I will tell you if you tell me what type problem your having . Plus if your planning to replace it ,it does need programming . An the dealer is pretty much the only one who can do that . I know there are no more Oldsmobile dealers any more . A Chevy , Cadillac , Buick , Dealer would be my choice. I work for A Cadillac dealer an see a number of Pontiacs an Oldsmobile vehicles needing the same work .
