I had the same problem with my 99 cobra. The dealership claimed they didn't get it from the previous owner who "traded in" the car. Anyways my buddy has a Mach 1 and had an extra remote so he let me have it. What I did to program the remote to my car was I pressed both the Lock and Unlock buttons at the same time (held them) and turned the ignition (without turning on the car) about 8 times. At that point the car should lock and unlock. The only downside is that it will still lock and unlock my buddy's car, but you shouldn't have that problem. Let me know if it works for you!
