Car Alarms: my alarm goes off at 4:30 am each night., 2001 mercury sable, mercury sable

Question
Help, my alarm goes off at 4:30 am each night...I've had several neighbors threaten my life if I don't fix it immediately...can you tell why it does this...and what I can do to fix it....the car is a 2001 Mercury Sable and it has a factory alarm.....thanks

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.
