The only way to find the real problem is to have the system checked over, though the years I have found bad key pads, defective door switches, grounding problems, door wiring shorts and even key fob malfunctions that can set off the horn. No simple answer here.

Mine had the same problem, the dealership replaced a sensor located in the driver's side door panel, forgot what they called it, but apparently it handles several functions, not good to slam doors on the cars.
