Car Alarms: disengaging a factory alarm, 2002 hyundai sonata, hyundai sonata

Question
I have a 2002 hyundai sonata. It has been sitting a while and im tring to jump the car but the alarm had gone off in it and ive misplaced the remotes. How do disengage the alarm completely?

Answer
I need to determine whether it's a factory alarm
issue or, if it's an aftermarket system you are
dealing with.

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)
Or,
is it: flashing parking lights,
an LED in the dash area, and a siren
going off?

Let me know more on this to better
advise you on a course of action
to take, to help you to fix this
situation you're in quickly.
