a hair pin? welll......at least they weren't real car thieves and at least they didn't really steal your car...lol.
Just get lo-jack...a real car thief can disable a car alarm pretty quickly. At least with lo-jack there will be one less car thief on the street 15 or so minutes after you call it in. At worst you'll get a broke window and ignition, but better than never finding your car in one piece again.
