Car Alarms: Car Alarm, alarmtek, neg terminal

Question
My 1994 Camry was installed with what I believe is an aftermarket security system which I never thought worked, until I did work on car and had to diconnect negative ground wire on battery. When I finished work on car and went to open door, the alarm went off and was unable to start car. I bought car used and was not given a remote for alarm, just a key for car. The only way I can silent alarm is by disconnecting neg. terminal on battery.
What can I do to disable the alarm and get the car started?

Answer
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.
