My mother has a 2006 Fusion and the remote key has died (PATS is fine - will start the car) I tried changing the battery but no life at all. I reckon the key has died but to check I tried to put the car into programming mode - I understand that turning from pos II to nothing 4 times in 3 seconds and then removing the key should do this and the led should come on without flashing.
When I do this on this car it beeps but the led continues flashing - any Idea what is wrong ?
