Blinking theft light, wouldn't start
 

I jumped in the truck on Thursday afternoon in our parking garage at work, stuck the key in and tried to crank the truck. Would only turn over, but not start. I checked fuel rail and had pressure, battery was still good, even though it is the original. I did disconnect it and let is sit for about a minute. Called the dealership and asked them what to look for as I was a block from the nearest road and no tow truck could reach my truck due to roof height. They said try starting with gas pedal to the floor and then depressed slightly, nothing. I did notice during this procedure that the theft light was flashing fast. Looked in manual and saw it said to have it towed. Called dealer back and they confirmed. Roll back on its way and I am stuck pushing this heavy bst to the street. Along the way, with the key in the ignition and the truck in neutral, it must of recognized the key. I noticed when I got to the road, the theft light had stopped flashing. I tried it and truck cranked right up just as the tow truck arrived. Luckily he said have a nice day, no charge to come get me! :thumbsup: to Ben Satcher Ford in Lexington,SC!
Has started fine since.
Should I be concerned that it needs to be looked at or replaced?

TIA

I'm not sure if the Key has a battery, but the pats works on a radio frequency. Perhaps the key has a dying battery?

Not sure about the ford system but the PATS in the honda cars is sensitive to metal key fobs. If you have something on the same ring as the key it might cause interference with the PATS. the key does not have a battery and does not work give off a radio signal.

Nothing but the factory ford key and the key fob. Almost 5 years to the day after leaving the dealership. No problem before, none since. Hopefully it was just a fluke.
