Car Alarms: re activate factory alarm, valet mode, lights and siren

Question
since putting a new battery in my 2003 gx rav4 the factory fitted alarm wont operate, what do I do to reactivate it ?

Answer
The "factory" alarm in this works with the physical
motion of lock and unlocking the doors either
by remote or with the key.
(HONKING HORN AND HEADLIGHT FLASHING)

If yours is aftermarket,
(PARKING LIGHTS AND SIREN)
then it's in overide.
Please refer to the user manual for reseting if this
applies to you, but for now,
try this.

Put the key in the ignition, and turn forward
all the way just before cranking. Then within
5 seconds, press and hold in the valet/overide
button, found under the dash area,
until the installed LED (the blinking light)
in your dash area goes off, and the siren chirps twice.
(Your valet switch might be the toggle (on/off) type.
in this case, key on, flip switch in oposite direction,
key off.)

This should reset the alarm.

Just Repeat these steps to place it
back to valet mode.

That should do it.

I hope it helps.
