Car Key with Remote Replacement Suggestions

[Golfer]

I just ordered 2 keys and 2 remotes for our '06 G6 and 1 key and 2 remotes for our '98 Grand Prix off of Amazon. The remotes were $25 a piece and the keys around $15. WAY WAY cheaper than going to a dealer. From a dealer the remotes would have been $80-100 apiece and the keys around $60. The G6 remotes required programing by the dealer, but the remotes for the Grand Prix could be programed by me as well as all the keys.
