if you have a 98 you can program your own heys.. I forgot how but its something like you put in your good key turn till lights on dash come on..stay there for at least 10 seconds take it out and put the second one in.. turn until the red light blinks twice.. to find out for sure go on ebay.. search for seller SandSlocks I think or search "ford contour transponder hey" He always had auctions selling them, and he includes instructions on how to program them...you just have to get somebody to cut it..ford dealer is best bet for that they usually cut for free.. I am not sure about the 99's and upp I hear they changed it to where you have to have 2 keys to be able to do it yourself..anymore questions feel free to ask!!
