stupid alarm...

Ok, not sure if anyone is gona know the answer to this one but, I've got an avital car alarm installed on my car. Problem w/ it is that it goes off when a freaking fly lands on it I duno if anyone knows how to tune it so that it doesn't go off all the time. Right now it's silenced, so it really doesn't do me any good Oh, and if you also know how to program it so that the trunk pops open using the clicker, that would be awesome. Thx.
