Where do you get a replacement key for a 2001 ford mustang?
You have to have the mustang at the ford dealership to be hooked up to their equipment and they will reprogram you mustang computer with the encoded PATS key. If you had a mustang that was 1996-98 you could just order the encoded key and do it yourself in about 45 minutes. But because of the anti-theft chip placed in these keys by ford, late 1998 and newer have to be reprogrammed at the dealer. Sorry for the bad news!
