When you set the alarm with the key fob the alarm does not resposnd the horns starts to blow you can not unlock the truck or lock the truck when this happens. the key fob is very sensitive any movement of the key fob causes the alarm to go off either locking and unlocking the doors or blowing the horn and you can not stop the horn from blowing.
I would start by replacing the FOB. Sounds to like the electronics inside it are bad. The only reason the horns would go off is if you hit the panic button. There is a slight chance the receiver is bad. But Fobs are cheaper to replace than the receivers. If you have two FOBs and they both react the same, then replace the receiver. Or just ditch the system. The keys (in the door locks) should still activate the alarm system.

Hello, although from your brief description of fault May I offer assistance? Not on a Chevrolet but a Volvo 740, the Button on the steering wheel for the horn are Copper semi circular type and sprung loaded. Me being ham fisted with annoyance pushed the button too hard, it worked ok at the time of use but a few minutes later World WAR 3! had to pull plug on horns themselves to silence them.
So FixYa resolution? Check Horn button itself Cuz it'll be stuck!

At first look, I would have guessed that your battery in the door opener was dead, but that is not the case. I suggest driving to a nearby Chevy dealer and ask one of the salesman if he/she can help. They have always been helpful to me. If not try another one as they are in business to sell not only cars, but service also. They will be your best bet to fixing it. :D

I too had this problem. I finally found out that my problem was the result of the metal contacts that touch the circuit board when you push the buttons had worn out. To correct my problem, I purchased a small pad that slides right inside the remote and fixes all the buttons. Since then, my remote has worked problem free for the past 3 months. The company that makes the pads is KEYLESSFIX. The following link will take you to the actual website:
