If you can not start your car and the alarm keeps going off, try this: find a alarm button , (probablyl under the dash) hold it in and try starting the car, then turn the key to accessory and this should disengage the alarm and the car should start.

When my alarm goes off, it usually happens when someone sticks their hand in the window to unlock the door. In order to turn off the alarm I close whichever door the person opened back, and unlock the door from the driver's side door. This usually turns the alarm off.
