Car Alarms: subaru anti-theft system, subaru legacy outback, outback wagon

Question
i bought a 97 subaru legacy/outback wagon about a year and a half ago.  it came equipped with an anti-theft system.  suddenly it has begun going off out of the blue.  sometimes it goes off when i use the key and open the door.  a few minutes ago it went off with nothing going on.  it went off for about 30 seconds then stopped.  my neighbors were displeased.  i looked in the owner's manual, but it does not tell you how to disconnect it...what do i do?  any suggestions?  thank you!

Answer
Not sure what aftermarket system you have
there, but this is what I think is going
on....

The alarm seems to be in long tamper mode.
You will need to reset, and possibly
re program the remotes. That part you will need
your manual for, but the aftermarket 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.
