Car Alarms: Car alarm going crazy!, rattler car alarm, dash area

Question
I bought a RAV 4 six months ago. There appeared to be a Rattler car alarm installed, but the LED light on the dash was never lit, and the remote on the keychain didn't work, so I assumed it was disabled. Yesterday, out of the blue, the car wouldn't start, and then suddenly the alarm started going off. (Never heard the alarm before. Didn't know if functioned.) The LED light blinks and everything. Now it goes off every time I touch the steering wheel or open a door, or look at the car sideways. Can't make it stop. I replaced the battery in the remote, and now the green light on it goes on when I push the buttons, but it as no effect on the remote. I just want to disable the remote so I can drive the car again.
Thank you  

Answer
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.
