Earlier Fords with PATS could only do 2 keys unless you bought an extra gizmo for inside the car.
The 2012 can do up to three keys.
Yeah they have to be programmed and have a chip.
Remember the new keys (2012) and later have the
laser cut' style key and not the old notches. So a key cutter would have to be able to cut laser cut keys. (not really a laser, but a different machine)
One good use for a non PATS key is using it to get the door open if you locked your keys in the car.
My last car I had a key cut which could ONLY open the door, and not turn the ignition. I kept it zip tied to the underbody for emergencies. (and actually used it once)
The Ti with push button start has some deal where you cannot lock your keys in the car if i remember my posts..
But not the regular ones.
