anti-theft system for 91 rx7

I am unable to use my alarm system because someone stuck something in my door lock in my driver's door and the passenger door has no handle at this time. I have not used it for quite some time. My alarm system has been disarmed but suddenly went off in the driveway and I disconnected the battery to keep it from going off suddenly. Is there a way to totally disarm the system? Is there a fuse? It is a 91 rx7. Thank you.

I didn't even know the security thing made noise or did anything, mine sure doesn't... so no help here, sorry

best bet is having someone who knows about alarm system check out what system is on the car, had a 90' but it didnt have any alarm system

haha...i didnt know mine worked either...untill...well for me anyway, it seems the only thing that sets it off is when u start the car while the passenger door is open. scared the shit out of me.
