Thanks All,
Just to let you know, I tried all the suggestions, including my owners manual. None of the things worked for me... ... ... . but, the suggestions got me thinking which made me look for the quick card that comes with all new 06 trucks. The quick card was different information than the owners manual, which in itself is confusing! Well, anyway the quick card said to stand out side the vehicle, press and hold the lock button for between 4-10 seconds but not longer than 10, then simultaneously hold down the panic button, then release both. Well that did it, and I got in the cab, set the alarm by using the remote on the key, then waited for it to arm. I opened the drivers door and the horn started really honking, so that must mean I didn't inadvertently disarm the alarm function. But now when I walk away from the truck and arm it, there is no annoying horn honk. Really appreciate the response from all of you guys! Stan
