I didn't think I was doing anything wrong..but here is how I made the car alarm go off: I put the drivers window down all the way when I parked the car in the driveway. Went inside with the keyfob. Came back outside without the keyfob to look for something in the car...figured I could put my hand in the open window, and open the door from the inside. The door opened, AND the alarm went off !! Scared the %# outta me. (old habits die hard...use to do this all the time with my ICE ) Morale of the story...always have the keyfob with you :smile: p.s. Pressing the top keyfob button turned it off.
