Car Alarms: Disabling Chapman Car Alarm, saturn sc2, dash area

Question
Hi, Thanks for the prompt respone. I'm not sure what you mean by "Key On"....and the button you are talking about is the one under the dash, right? Because I do not have access to the remote. Lastly, even though it is a silent alarm, will there still be a siren that chirps?

Thanks again.

-----Question-----
I bought a 97 Saturn SC2 used. It has a Code Alarm Chapman Security System...when I bought the car, they no longer had the remote for it, so I just used the button under the dash when starting the car.  Now that button no longer works. I can start the car, but the alarm keeps going. It is a silent alarm so it is basically the lights that keep flashing. I would like to disable the alarm. Can you help me, please?

Try key on, press and hold the button for
about 6 to 7 seconds. When the siren chirps.
it's disabled.

If no joy, you will need to remove it.

Answer
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.

(if the siren was removed, then obviously
there will be no chirps. but if in valet,
it may have simply disabled the chirp in that mode.
