My car alarm goes off every day - usually around 10:30 am give or take 45 minutes. Once it went off at 5am and occasionally it goes off more than once a day. It is not windy and there is no one near the car, etc. I see that other people leave their car unlocked to avoid this, but I live in an area with bears. No one will steal the car, but the bears get in and wreak havoc. I don't want my neighbors to hate me!! I am scared to mess up the anti-theft system because I recently heard a horror story about someone who bought a used car. The anti-theft system malfunctioned and the car won't start now without a 3K fix. Car isn't worth 3K, so it's totalled. I want to avoid that at all costs because despite the fact that the car is 12 years old with 149500 miles now, it's in good driving condition with new brakes, tires, leather seats that clean up nicely, etc.

I am wondering if it is triggered by someone's garage door opener or similar electronic radio transmitted signal. I don't mind losing the alarm function completely since it isn't very likely to be stolen anyway. I just don't want to risk causing a problem that will make the car refuse to start!
