2004 f-150 4.0Already Tried: new keys from the ford dealership & diagnostic check
You really need to find someone (a technician) that understands how the system works. Talk to the mechanics instead of the service advisors. when describing your concern. Keep in mind that the more information that you get to the technician, the better the chances of your truck getting fixed.
As for now, the next time that the anti theft light is flashing. switch the key right off, adn change the position of the steering wheel (the tilt). I don't know what model 04 you have, but the Heritage f-150 does have a problem with the wires from the PATS transpoder breaking at their connector at the bottom and causing your concern.
The PATS transponder is the sensor ring that is mounted to the igintion lock cylinder that senses the ignition key code.
