I was staying in a motel in Canton, New York... it must have been the only one in the US which didn't have AC. One Saturday night I had just gotten to sleep with the windows open when somebody pulled in right out front. They got out and I was awakened by their horn going off as they set the alarm. I had just gone back to sleep when "Honk!" they had gone out to the car, then armed the alarm again. That went on for a couple of hours... I would just get to sleep and their damned horn would go off again outside my window.The DIC was broken on my 2003 Suburban when we bought it. (Driver Information Center, but it's more fun to day DIC). Therefore, I cannot turn off the horn alert when locking or unlocking the doors. So:
BEEP! - lock
BEEP! BEEP! - unlock
When I left for work a few hours later it was all that I could do to keep from kicking their tires to see if I could set the thing off for real.
