Car Alarms: Keyfob has disabled my moms car and alarm will not stop, alarmtek, dash area

Question
My mother dropped her keys in the parking lot and a car ran over them, busted the keyfob and now when she turns her car on the car alarm keeps going off.

Answer
Make, model & year of the vehicle?

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.
