my alarm freaked out a couple of weeks ago, it sounded like i had R2-D2 trapped under my hood!
you are lucky it didn't screw with your thermostat relay, i had to purchase a new battery and replace the thermostat. Not to mention I had to completely remove my alarm/automatic starter.
I'm hoping it isn't that! but yeah i agree with mrhonda.
hopefully it's only that...i think my alarm/remote start was old and just croaked
