I know that mitsubishi sells them for about $80 a piece and $90 to program.... If you can get a better price that would be cool, and ask your friend how they program the remotes, I heard that you can program them by holding the button in front of the radio for 3 to 5 secs. But i dont know thats what i heard. And if it is true how will that work if you dont have the stock radio in anymore.
