I have a 2013 Ford Explore Limited. I purchased it used about 5 months ago. We had to replace the battery this weekend and now every time I open a door, the horn honks twice. When I get out, close the door and arm it, the horn honks once. It never did this before I replaced the battery. I've checked the manual and I don't see anything in there about disabling the honking. Side note - the dealership told me I have an aftermarket alarm. I have zero info about it as it was already installed when I purchased the vehicle. I have the intelligent access Ford key fobs - no separate alarm remotes. Anyone know how to fix this?
