After loosing one of the two keys for my Ford pickup I ordered an OEM key off EBay, loaded Forscan on my laptop, and the Forscan recommend OBDII adapter from Amazon. Got the key cut at a locksmith and then used Forscan to program the key. Twelve minutes latter the new key was all set including it's buttons for doors and remote start. I paid $100 for the key but it's a genuine Ford key. There are aftermarket keys on Amazon for $30. I may try one if I decide I want a 3rd key.
