Anyone have any experience using scanners that will program new key fobs? Both my 2004 and 2008 Grand Prix's are down to one fob. I would rather not go to the dealer, a locksmith coming out to do both is an option but if there is a scanner that would do it for a couple hundred bucks I would consider that also. I already purchase new fobs for both off eBay. Any thoughts or suggestions is appreciated. Thanks
