Car Alarms: dodge ram and factory alarm, dodge ram 1500, alarmtek

Question
I have a 2004 Dodge Ram 1500 with a factory alarm that somehow was triggered when trying to get into the truck.  Now the truck won't start.  I have tried everything I can think of.  Not sure what else I can do.  The keyless entry doesn't help, and neither does the key.  I hve heard that there is a switch to reset the alarm, but not sure where to look.  Any insight would be great.  I hate to think that I will have to pay to have my truck towed to the dealer just to have them do 5 seconds of work and charge me a hundreds bucks.  Thanks.

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.
