It sounds like there is a short in your alarm system. You should take it to the dealer or a reputable car shop to fix the problem. This could be a costly venture and, if it is in fact your alarm system being faulty, you can remove the alarm's chip to make it inactive.
Where is the alarms chip? This problems is kill'n me.....

I had the same problem but it turned out that my car battery was getting weak and since I have replaced the battery, my neighbors don't complain any more. It was a simple as that. Gene
