I don't think the alarms will go off when popping the cylinders and unlocking the doors that way, but if you had a window partially down and someone sticks there hand in and uses the power unlocks it will go off

Actually, they can disarm the alarm from popping the lock. All that needs to happen is the green wire inside the lock to see ground to disarm. ALso, your truck might not have content theft alarm but jsut the passlock system instead.

Where is this green wire ?
Also my Alarm doest work now, is it because of this green wire ?
