if your car came with a stock alarm even if they broke the window the alarm still probably wouldnt of gone off but once they pull the handle and unlock it when the door pops open then tha alarm goes off thats how my boys 07 subaru was until he got after market alarm someone smashed his shit and dipped no alarm no nothing then in the am when he opened the door it went off so much for stock alarms..but good luck getting it resolved bro that sucks insurance ftw
