Car Alarms: Replacing Battery, dash area, button spring

Question
Alright, I see the light on my dash...and i have a toggle switch beside it that  im not sure what it is, I tried teh method several times with that in different key locations, so i looked under the dash and saw a very small springloaded button(smaller diameter than  a pen) so i tried it with that...no good either.  Now when i close the door the alarm goes off quiet and gets louder and louder until i open the door again.  any follow up adivce would be grea tthanks :)

Hi, I am trying to put a new battery in my 1994 GMC... my alarm keeps going off and after I have the cables installed the truck won't start.  Any ideas?

Ok once you power up the system, the
aftermarket alarm senses it and triggers.
Let's try valet overide to reset it.

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.

Ok, but the alternative is not great.
You will need to locate the alarm brain,
unplug the harnesses, and then reset the system,
and try again, or remove it completely,
repair the wiring including cutting out the
starter kill relay inline, and start over
with an alarm you have complete knowledge
and control over.

Try the key on, flip the switch you found, then key off,
Or make certain the button you found is held in long
enough. Sometimes that can make all the difference.
