Car Alarms: 1996 acura tl , alarm stuck on, acura tl, alarmtek

Question
i unlocked my car, then opened the door, not sure if i hit the lock,or any other button on the remote while the door was open..but the alarm went off, i have tried to put the key in the ignition,while pushing the unlock button on the remote..  but still can't get it to shut off ???

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.
