Car Alarms: 1996 Buick Park Avenue, buick park avenue, alarmtek

Question
We had just come home and were sitting in the house when the horn on our 1996 Buick Park Avenue started blaring, does this have anything to do with the anti theft system and what do we do to stop it? Right now we have disconnected the battery.

Answer
Is it: Headlights flashing, car horn honking
and a worded SECURITY" light in the dash flashing?
(doubtfull since none of the notes show this
car as having a factory alarm system)=FACTORY

Or,

is it: flashing parking lights,
an LED in the dash area, and a siren
going off?= AFTER MARKET

Let me know more on this to better
advise you on a course of action
to take.
