What happened?? Keys erased!!
I disconnected my negative battery cable to mess with my speaker box in my truck. After i was all done, i hooked the cable back up, turned just the power on, and i heard clicking from the engine, so then i tried to start it, and it would crank, but wouldn't start. So i called FORD. The told me to check all kinds of stuff. But none of it worked. So i called FORD back and they had it towed to the dealership. Ended up, the computer was erased and didn't remember the keys anymore (the microchip keys). So my keys couldn't start the truck. What happened?????? FORD didn't know either. They just charged me $177 for the diagnostic and reprogramming of 2 keys. My 6 year, 100,000 mile warranty would not cover it!!! Bull. Lemme know guys.
