2001 SC2, locator/alarm keeps randomly going off

My locator/alarm started randomly going off today, I have no idea what the cause of this could be. The button on my keys isn't being pressed or anything. Any ideas???? Thanks

weird. my aftermarket alarm which has a vibration sensor goes off everytime i set my alarm and sometimes the alarm itself goes off... i've had the alarm for over a year now and its JUST starting to do this... i'm wondering the same thing actually
