Everynight it thunders outside my car alarm will honk twice then stop throughtout the course of the night. Although I like to **** my neighbors off this is becoming annoying to me. I have done some research on this and think it has something to do with the shock sensor. How do I set it to a lower setting so it wont go off everytime it storms? If you dont think it is this, how else can I fix the problem?

Thanks.
