Your vehicle is supplied with two kinds
of keys.
1. Master keysÐThese keys work in ev-
ery lock.
2. Sub keyÐThis key will not work in the
glove box.
To protect items locked in the glove box
when using valet parking, leave the sub
key with the attendant.
Since the side doors can be locked with-
out a key, you should always carry a
spare 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 writing down the key num-
ber and storing it in a safe place.Your vehicle is supplied with two kinds
of keys.
1. Master keys (black)ÐThese keys work
in every lock. Your Toyota dealer will
need one of them to make a new key
with a built- in transponder chip.
2. Sub key (gray)ÐThis key will not work
in the glove box.

A transponder chip for engine immobilizer
system has been placed 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.
To protect items locked in the glove box
when using valet parking, leave the sub
key with the attendant.
Since the side doors can be locked with-
out a key, you should always carry a
spare key in case you accidentally lock
your keys inside the vehicle.
NOTICE
When using a key containing a trans-
ponder chip, observe the following
precautions:

When starting the engine, do not
use the key with a key ring resting
on the key grip and do not press
the key ring against the key grip.
Otherwise the engine may not start,
or may stop soon after it starts.

When starting the engine, do not
use the key with other transponder
keys around (including keys of oth-
er vehicles) and do not press other
key plates against the key grip.
Otherwise the engine may not start,
or may stop soon after it starts. If
this happens, remove the key once
and then insert it again after remov-
ing other transponder keys (includ-
ing keys of other vehicles) from the
ring or while gripping or covering
them with your hand to start the
engine.

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.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.
In the following cases, 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 inconsistent-
ly.
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 built- in 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 immobilizer sys-
tem. If any unauthorized changes or
modifications are made, proper opera-
tion of the system cannot be guaran-
teed.

3. Hold the hood open by inserting the
support rod into the slot.
Before closing the hood, check to see that
you have not forgotten any tools, rags,
etc. and return the support rod to its
clipÐthis prevents rattles. Then lower the
hood and make sure it locks into place.
If necessary, press down gently on the
front edge to lock it.
CAUTION
After inserting the support rod into
the slot, make sure the rod supports
the hood securely from falling down
on to your head or body.
To deter vehicle theft, the system is
designed to sound an alarm if any of
the side doors, back door or hood is
forcibly unlocked or the battery termi-
nal is disconnected and then recon-
nected when the system is set.
The alarm blows the horn intermittently
and flashes the headlights, tail lights and
turn signal lights, and turns on the interior
light.SETTING THE SYSTEM
1. Turn the ignition key to the LOCKº
position and remove it.
The indicator light will start flashing when
the key is removed from the ignition
switch. (See Engine immobilizer systemº
on page 17 in this Section for details.)
2. Have all passengers get out of the
vehicle.
3. Close and lock all the side doors, back
door and hood.
The indicator light will remain on when all
the side doors, back door and hood are
closed and locked.
