I guess he or she must have left for the evening and left that loud obnoxious thing on something loud like a jet set it off, how do I stop it? it‘s driving me nuts.
type write a letter and tell them next time you will call the police if they don't reset their car alarm sensor because it's to loud. Give them a few days to get that fix lets say 5 days then if it happens again or anytime, call the police for an alarm that is too loud in the night and call from a payphone so you won;t get yourself in trouble with your neighbor.
Call AAA and tell them and they'll pull out the spark plug. You should probably call them or knock on their door before you do this though.
