    One of the switches is probably bad, and it thinks someone is trying to steal the car. Pop the hood and look for a plunger on the left side - that's the sensor for the hood. If you push it a couple times, the alarm will go into a "test mode" where it will beep every time you do something. Open/close the hood, open/close the doors, and see if it doesn't beep for one of those.

    The test mode will automatically end after several minutes. With another beep.
