Mine works when it wants to. Sometimes when I get out, the lock button won't work until the courtesy lights turn off. If I open the liftgate, about half of the time, it kills the keyless completely and I have to manually shut it. It does lots of strange things. Anyone else?
So I took it to the dealership today... They said that they had no idea and reprogrammed both keys to the car. Still doing it. They still have no idea. Apparently, they have a call in to Ford to see what they think.
