Ok, i now have gotten an answer from my dealer about the 2-way key fob for my 08 G6 GXP, i need the $150 dollar one. But here is my next question. They told my wife that they "had" to charge an additional 99 dollars to reprogram all my key fobs. I know I can do it myself but, is there and additional computer flash or something they have to do to make the 2 way key fob work? Any help would be appreciated. Thanks in advance.
