Car Alarms: Rav 4 car alarm, toyota rav 4, valet mode

Question
I have a 1999 T reg toyota Rav 4. The last few months the car alarm has been going off for no apparent reason. It seems to be doing it during or after heavy rain, then the day after be ok. This is driving my neighbours mad as its happened in the early hours. Its a Toyota factory fitted alarm and immobiliser. Please help !!!!

Answer
It's an after market system from your description.
Probably dealership installed when
it was purchased originaly.

The shock/impact sensor seems to be the likely
culprit here.

It's usually to be found under the dash area,
blinking when anything taps on the underpanel.
Locate and either unplug or turn down.
To simply disarm it, locate and use the
valet/overide switch.

To start, look under the dash area for a button or,
a toggle switch. When you locate it, turn on the
ignition key, press and hold in the button (little
spring loaded micro button, red or black possibly)
until the alarm chirps 1 time. This should over ride
the system, and only the keyless entry part,
if installed, would still be operating.
The LED (light emiting diode) light in the dash
should also go on solid.=VALET/OVERIDE

This stops the alarm except for the keyless
entry if installed. The next step is to
either remove the alarm or, try to identify,
and get new remotes for it.

But once in Valet mode, it will allow the car
to start and operate like there was no alarm at all.

Let me know how it goes.
