DAVE

in florida i had the pleasure of seeing an individual at a stereo shop install a set of door blockers. they drill a 3/8inch hole in the door and door surround, and install them with some actuators so that when the alarm is activated the steel bar slides into the hole. kinda like a gate latch, the door COULD NOT be opened, only option was to break the glass, but then the thief would have to CLIMB all the way into the car.

i saw how they did it and its nothing too ingenious about it, combine this with an alarm and a manual kill switch, i dont see much happening
