Car Alarms: 2004 hyundai car alarm, 2004 hyundai elantra, hyundai elantra

Question
my friend has a car alarm(factory installed) on her 2004 hyundai elantra and it wont stop going off.she went out to shut it off,now she cant put it on at all. whats wrong? can it be reset?if so how?

Answer
Please be more descriptive if possible.

"GOING OFF?"

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)=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.
