Car Alarms: GMC Suburban Alarm, gmc suburban, dash area

Question
How do I disable the alarm on my 1996 GMC Suburban?  It goes off frequently because the doors are unlocked, and kids will open the doors without the key push-button.  This sets off the horn beeping and everyone is grasping for the button to turn it off.  I believe this is the factory installed system.  It has a red LED light on the left side of steering colum.  The owners manual provides no information.
Thanks,
Chris

Answer
The alarm seems to be doing it's job.
At least we know it's installed correctly
which is actually a good thing here.

But from the sounds of it, I would have
to say there is a conflict between the factory
alarm, and the aftermarket system.

Ok, try this.
Put the key in the ignition, and turn forward
all the way just before cranking. Then within
5 seconds, locate, press and hold in the
valet/overide button, found under the
dash area, (push button, spring loaded)
until the installed LED (the blinking light)
in your dash area goes on solid,
and the siren chirps once.

(Your valet switch might be the toggle
(on/off) type. in this case, key on,
flip switch in opposite direction,
then turn the key off.)

This should reset the alarm, and reset
the grounded relay on the starter wire,
allowing you to start the engine.

At this point, the only thing working would
be the keyless entry from the alarm,
if it came equipped that way.

Just Repeat these steps to place it
back to usable armed mode.
You may get 2 chirps, confirming it,
and the lights may flash twice as well.

That should do it.
If you want to remove it at this point,
take it to your neighborhood installer
for this, or buy the wiring chart
(Go to: www.vehiclewires.com)
for the vehicle, and reverse engineer it wire
by wire, until safely removed.

If it does not work out this way,
you will have to replace the system
with one you know how to operate
and what to expect. Don't want to
get stuck in another bad situation.

Let me know what happens.
