Car Alarms: Factory Alarm, valet mode, infiniti truck

Question
I have a 1997 Infiniti truck and it came with a factory alarm.  But the alarm is going and as a result it locks up the truck and it won't start.  I brought it to the dealer and they said they cannot override the alarm.

Can anyone help me figure out how to disarm the alarm so that i can drive my truck?

Answer
It's an after market system from your description.
Probably dealership installed when
it was purchased originaly.
Try the following:

To start, look under the dash area for a button or,
a toggle switch. When you locate it, turn on the
ignition key, press and hold in the button (little
spring loaded micro button, red or black possibly)
until the alarm chirps 1 time. This should over ride
the system, and only the keyless entry part,
if installed, would still be operating.
The LED (light emiting diode) light in the dash
should also go on solid.=VALET/OVERIDE

This stops the alarm except for the keyless
entry if installed. The next step is to
either remove the alarm or, try to identify,
and get new remotes for it.

But once in Valet mode, it will allow the car
to start and operate like there was no alarm at all.

Let me know how it goes.
