When I got my car it only had one key and no fob. Fobs I can get off ebay cheap, I guess I'll have to get a key blank there also. Ford has a security system called PATS that uses a computer chip / transponder in your key. The car's computer won't start the car unless the chip talks to it. My car was made in 08/98 so that makes it a late '98 which is a bad thing if you only have one key. With two keys I could get a blank cut and follow a process that will program that other key. Since I only have one key I have to get another one made.
At lunch Friday I went by Tim Stewart Ford Lincoln Mercury at 5675 Peachetree Industrial Blvd, Atlanta, GA 30341 and went to the parts department to have a key made. They told me it was $45 for the key and $90 to program it for my car. I'm not going to pay $135 for a key! So I'll have to call around to independent locksmiths or find a way to defeat the PATS systems so I can us a normal skinny $1.25 home depot key.
I have also read that some Ford dealers will not rape you for the cost on programing your key. If that is so then shame on you Tim Stewart Ford Lincoln Mercury!
