of keys.1. Master key—This key works in every lock.
2. Sub key—This key will not work in the glove box.
To protect things locked in the glove box
when you have your vehicle parked, leave
the sub key with the attendant.
Since the front doors and sliding doors
can be locked without a key, you should
always carry a spare master key in case
you accidentally lock your keys inside the
vehicle.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 you to write down the key
number and keep it in safe place.Your vehicle is supplied with two kinds
of keys. 1. Master key (black)—This key works in every lock. Your Toyota dealer will
need it to make you a new key with
builtin transponder chip.
2. Sub key (gray)—This key will not work in the glove box.
A transponder chip for engine immobiliser
system has been filled in the head of the
master and sub keys. These chips are
needed to enable the system to function
correctly, so be careful not to lose these
keys. If you make your own duplicate key,
you will not be able to cancel the system
or start the engine.

The engine immobiliser 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.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 any of the following indicator conditions
occurs, contact your Toyota dealer.
The indicator light stays on except
when the theft deterrent system is set-
ting or activating. (See “Theft deterrent
system” in this section.)
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.
For your Toyota dealer to make you a
new key with builtin transponder chip,
your dealer will need your key number
and master key. However, there is a limit
to the number of additional keys your
Toyota dealer can make for you.
If you make your own duplicate key,
you will not be able to cancel the sys-
tem or start the engine.
NOTICE
Do not modify, remove or disas-
semble the engine immobiliser sys-
tem. If any unauthorized changes or
modifications are made, the proper
operation of the system cannot be
guaranteed.
