Just want to say thanks to all. You guys saved me $400 dollars. I ordered the remote button transponder key from ebay, like you guys said ($80.00). I recieved it in two days. Followed the instructions you gus gave to program it, it worked great. The stealer wanted to charge me $500 to do the same thing. $250.00 for the key and $250 to program. I have had the 99 for a week now this was my first project.
