i think shorebird is right. each time you reprogram the computer, you must put in ALL keys you want to use. it erases the old numbers (except the two originals) and then add the new keys. so yes. you could have two "A" for one car, two "B" keys for the other, then program in two "C" keys that will work in both. BUT, you need to cut the lock on one car first to match the other lock.

Ford, Lincoln, Mercury Passive Anti-Theft System (PATS)
Many of the Ford, Lincoln, and Mercury vehicles sold since the late 90’s have come with an anti theft system known in the industry as PATS (Passive Anti-Theft System). PATS uses radio frequency identification technology to prevent the vehicle from being stolen. PATS uses a specially encoded ignition key. Each encoded ignition key contains a permanently installed electronic device called a transponder. Each transponder contains a unique electronic identification code. Each Key's code is completely different so each encoded ignition key must be programmed into the vehicle's instrument cluster module, before it can be used to start the engine.

OK but I've got a locksmith and the Ford guy who does the keys at the dealer telling me the key is getting reprogrammed so it won't work in Car A after it is programmed to work in Car B.

According to our senior tech you can program the keys from one vehicle to work in another vehicle as well, however, you will have to rekey one vehicle to match the other
which will be expensive for the parts and labor on top of the cost of the keys and programing. Which begs the question---'Why"?. You can only drive one vehicle at a time
so you only need to carry the key for that particular vehicle. I separated all my keys years ago when I kept wearing holes in my pants pockets prematurely from the wad of keys i was carrying. Dan.

If you only have only one chip key and you buy additonal keys;
Has any F-150 owner been able to program the additional keys by
using the ONE ORIGINAL KEY TWICE. I have noted post that say
this is possible with some vehicles.
