KEY NUMBER PLATE
Your key number is shown on the plate.
Keep the plate in a safe place such as
your wallet, not in the vehicle.
If you should lose your keys or if you
need additional keys, duplicates  can be
made by a Toyota dealer using the key
number.
We recommend writing down the key num-
ber and storing it in a safe place.
Engine immobilizer system
SB12047
The engine immobilizer system is a
theft prevention system. When you in-
sert the key in the ignition switch, the
transponder chip in the key’s head
transmits an electronic code to the ve-
hicle. The engine will start only when
the electronic code in the chip corre-
sponds to the registered ID code for
the vehicle.
SB12092
The system is automatically set when the
key is removed from the ignition switch.
The indicator light will start flashing to
show the system is set.
If either of the following indicator condi-
tions occurs, contact your Toyota dealer.
The indicator light stays on.
The indicator light does not start flash-
ing when the key  is removed from the
ignition switch.
The indicator light flashes unsteady.
Inserting the registered key in the ignition
switch automatically cancels the system,
which enables the engine to start. The
indicator light will go off.
