Not how I handle neighbors' car alarms, but to each their own I suppose.
Musician Turns Neighbor’s Car Alarm Into Keyboard Jam

This is a video of musician Tony Ann turning his neighbor’s annoying car alarm into a tasty keyboard jam, proving that music is all around us (and not just waiting in my roommate’s butt while asking if I want to hear a jazz riff). And if Tony is this good with a car alarm, just imagine the opus he’ll produce from the construction noise of that apartment building being built!
