For sale is a new ignition key (uncut) and fob (unprogrammed) that fit 1999-2004 Mustangs. The fob contains lock/unlock/panic/ and trunk release buttons. Your car would need to have these functions on your present fob. I purchased the set and have decided not to use them. The key can be programmed at any Ace Hardware Store and the fob can be programmed at home as programming instructions are included; no need to visit a Ford Dealer! Asking $50.
