Passive Anti-Theft System
I have a 2011 F150 S. Crew that's about 2 months old. Last night I locked the doors like I normally do (hit the lock button on the key fob once), I heard the doors lock and the lights flashed once. Around 2:30 in the morning I heard a horn sounding for about 20-30 secs. but I didn't think it was mine...This morning I go out to start my wifes car, and go over to the truck to see if the door was locked, I pull the handle and the door opens...It was not locked and the keys were inside the house in a key cabinet all night. There was a chirping that started inside the truck as soon as I opened the door and the message centre said I had 15 secs (or maybe 20 i forget) to start the truck. I didn't have the key with me so I hit the lock switch on the inside of the door and closed the door...then all heck broke loose, lights flashing, horn beeping, neighbors waking up. I went inside and hit the panic button on the key fob and it stopped. When I went back outside, the doors were locked and all appeared normal. I walked around the truck and all the doors were properly closed, all the windows were up, the locks and keypad were fine and the hood was closed ( I don't think the hood is attached to this passive theft system, but just thought I'd mention it). There is no factory or aftermarket alarm system installed. The window sticker just lists the Passive Anti-Theft System, like my previous 4 trucks and I've never had this happen. Anybody have any ideas what I should check? I looked in the manual and it doesn't say much about trouble shooting.
