So far it sounds like 2 new keys just need to be programmed to the vehicle. That is the first thing you need to try. If you cant even access the security section of the PATS system after the 10 minute wait period then you will know there is a module concern then if the keys will not program then you know you have a PATS transceiver issue. The code says the amount of keys programmed is below minimum. The minimum is 2 . See the Ford diag steps below.
