Well just an update. I ordered a switchblade key for my 99 GT. I ordered it from a vendor on ebay. I had to wait two weeks as the first was lost in the mail. The replacement was sent and I received it today. I have to say that it would not program when I was programming it. I took it apart to see if it was the battery but I noticed that the pellet for the theft system was missing. It was not installed in the unit. Also becareful when putting everything back together. If it is not installed correctly the flip key mechanism will not work right. I am sending it back for a refund.
