I think that's part of the Immobilizer system, but how is it possible that the two keys lost the programming? I checked again today my car in the dealership because I had to rent one because my job is one hour away from home, and the manager told me that they tested the start/stop button, the safety system, and everything was fine but the clutch sensor. I still don't think that the problem because when the Fu*** car is warm it starts every single time!!! So you're telling me that the clutch sensor warms up and then works every time? Don't buy it.
Where is the person from Ford Service that writes in the forums when you need him/her?
Anyways, I'll check the car again on Thursday to see that it's in the same state.
