Dont want or need a real car alarm Just something something simple that makes noise when they open the door (and/or move something) I was thinking about a personal protection siren rigged to the door so when they open the door past 6 inches it would go off (they wouldnt be looking for the string at night + I could reach in and disarm it) although id have to sprint to the parking lot as the thing is LOUD but Im curious to hear your boobytrap ideas .
