Car Alarms: 94 Camry Alarm, alarmtek, dash area

Question
I purchased a 94 Camry from a used car dealer.  Recently I had a new battery put in, and every time I open the driver's side door (from in or outside), the alarm goes off.  I tried using the keychain button the dealer gave me, but it doesn't appear to work (I even got new batteries for it, but no luck).  I didn't realize the alarm actually worked, and I have no idea how to get it to stop going off so I can drive.  Any suggestions?  And how to I avoid this the next time the battery is disconnected?

Answer
The 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.
