My alarm is definitely not broken. My alternator went out and so I had to leave my car at my aunty's house. The hood was open but all the doors were locked so when I went to disconnect the battery the alarm went off. The awesome part was I had stupidly forgotten my keys at home so I got to listen to this go off for 5 minutes until whatever reserve it had died out. I thought it was a really cool feature and makes the car that much harder to steal.
