I went to the junk yard to get some parts for my bonneville and got two lock cylinders with keys in them for my grand prix.1 came with the remote but the key i believe is coded because it has the pk3 on the key.the other lock cylinder did not come with the fob just the key and doent have anything marked on it.im guessing its not coded.if i ever get my old cylinder out could i use the non coded key and cylinder and put it in or will it need to be programmed or something by the dealer?my car or the one from the junk yard didnt have that delphi box by the ignition.
