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
