hi graham im not sure but i think you might be able to get a key cut so you can take your remote fob and use it streight onto the new key but you should be able to just get a key cut as normal aswell i would ring ford up just to inquire about it first it doesent mean you have to get it from them if not goto key cutting place and just ask if they do one were you can just exchange the keyfob hope this helps you out
