Thanks, do you know if this will work on a 2003 S Type R? I see from my search it has been used on a 3.0 but not sure if the system is the same.Here you go: programming keys
Its a thunderbird but the process is the same. Keep in mind: make sure you have your car and laptop battery full and connected to a charger when doing this.
Forscan does the same thing. I had only 1 key so i added 1 key extra. X200 this works but i never tried it with a later S type. You need to go to Forscan > Service procedures > Pats programming > Then you get a popup, click OK > then you get a menu where you select Spare key programmable. Then you get popups with instructions you need to follow.With the Ford, I was able to simply add another key without deleting any. I had the option to delete all known keys, and I could have programmed just the one key if that was all I had, so the two systems do differ.
