What different methods trip the alarm. I know if the windows are down and you reach inside and open the door it goes off.If you reach in and pop the hood, while its set, the instant you go to open the hood it trips. Lets say all the windows are up, all doors are locked, what would trip the alarm?Last night at my friends the alarm went off in the dead of night, and it never goes off, without me doing one of the things mentioned above.Some one also busted a light out around my friends car so it would be darker while they try and do there dirty work.His car was in the backyard, mine was in the front on the street,but we were both affected.Keep in mind that the theifs are more concerned with the contents in the car than the car itself. Also i made it down a flight of stairs out the backdoor and ran around front inless than 15seconds so there going to have to fast.
