The GM ones are easy with the programmer and I've never been charged for the service, however if I ever had a place want to charge me I'd do it manually. Not sure on the Ford, but GM is done by going into the learn mode and letting 2 lbs of air out of the tire. The horn will sound once when the location is learned and then you move around the vehicle clockwise until all 4 are learned at which time the horn will sound twice. GM has been using this same method for as long as I can remember and on every vehicle I've owned with TPMS system.
