Hi all, I have a similar issue to what I've seen others have but mine seems to be worse. The alarm started going off when the car was unlocked with the boot open and I couldn't stop it with the fob. Figured out how to stop it, assumed it was the battery, got home and the spare fob won't work either. The message it says is alarm service required and it often says key not detected. Took it to an electrical specialist today who said it's show external alarm sensor fault, they didn't know what or where this was and apparently neither did the Ford dealership they spoke to. I'm thinking of getting an auto locksmith to reprogram the keys but wondering if that'll just be more money wasted. Anyone got any ideas? Apologies if this is posted in the wrong place, I'm new around here. Thanks.
