Expert:  Lou P. master tech replied 1 year ago.

Ok the siren is a small module located in the wheel well on the passenger side. Most likely the siren has failed internally which is setting off the alarm. shut the car off and lock it and then unlock it the alarm should go off. If it does then you should disconnect it or replace it. I'll send you a photo of it.
