the fobs were re -programed twice by the dealer with both vehicales seperated . They then replaced the 4 keyfobs and reset them and the new keys did the same thing. They then reset the car with new codes which worked for 2 hrs. They then started operating both cars again. Its weird as a couple keys would not switch over ,but within a couple of days they were all doing it again. I would have thought fords would be more interested because it is so weird but the opposite seems to be happening .Its as if they don't want to hear about it.Makes me wonder if it's something more seroius then just my 2 cars.
