if theft light is flashing fast with key on, pcm either lost key code or key sensor ring around ignition switch is bad. can try to have keys reprogrammed. best to get to dealer for reprogramming.
It is very easy to program PATS 1 keys yourself. I have found you can even lose your keys and have a new key cut for the ignition and program an original key yourself. No need to take it to a dealership with the expensive BE they will try and feed you. Go to and put your vehicle info in there and it will explain step by step on how to do tbis. By the way ford expeditions are pieces of junk. I own one and it is a money pit. I just reprogrammed an original key yesterday and programmed a spare this afternoon. P.s. if your magnetic ring around the ignition is bad just go to a salvage yard and take one off another expedition of that year and the magnetic ring itself can be removed from the module and replace the one in your truck. I have done this and worked. All said and done. SELL IT AND BUY A CHEVY!!!!
