If its the same process as older fords... its
turn ign on to ign 1 or 2,.... then off, 8 or 12 times... cant remember which until you hear a beep... then push the lock button on the fob with ign on... doors will lock. then turn ign off, then fob should work
or very similar to that

Cheers mate, i found this..
Try this procedure to re-sync key.
Fasten front seat belts and close all doors so that conflicting audible warnings do not sound when carrying out
programming.
Switch ignition ON 4 times within 6 seconds.
