i know fore sure you need the red key to program your pats! unless you get 2 cut and tie wrap yours to the transponder ring
i have the same problem with my focus! i only have the 1 key

the remote fob is easy to program and can get one from the scrapyard but i think you need 2 keys to program the pats transponder....?? anyone know if thats true? if i were to sort a key out and have it cut etc would it be cheaper as they just need to program the chip....??
cheers guys, sorry to high jack the thread
