Car Alarms: disabling unknown aftermarket alarm, isuzu trooper, dash area

Question
Hi Alarmtek,

I bought a 94 Isuzu Trooper in California and shipped it to my
summer home in Masssachusetts.  I did not know the car had an
alarm.  The car sat for the winter, and when a friend went to
start the car this spring, the alarm went off and would not
permit him to start the car (some kind of ignition defeat).  Any
suggestions on how to defeat the alarm and get the car running
again?

Thanks!  

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

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.
