Is their anyway you can make the horn beep, when locking the car or when opening the car?? I had this on my old 2006 Ford Ranger, and My 2008 Mercury Milan. Helps to find your car in a parking lot, when you forget where it is parked.Can not believe that is not on these cars!!!! Their is alot of little things you need to really check out, when buying a car, which sometimes is important.
