Car Alarms: Typical delay built in when key is used, car alarm systems, alarmtek

Question
My daughter is stuck in a parking lot because she had to use the key to access the car on failure of the key fob to open the car.  The alarm went off - but now she thinkgs the battery is dead, but I recall this happened before.  How long is the typical delay built into car alarm systems before it will start w/ the key?

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.
