When you lock your truck simply push down the manual locks. This will not arm the system. If you use the key fob to lock the doors or use the electric door switch to lock the truck then your system will arm. I have an issue where my horn will beep three times when I unlock my doors for unknown reasons. It only happens occasionally but at six am that does not make for good neighborly relations if you know what I mean. lol I usually manually lock and avoid arming the system altogether.
