KEYS AND DOORS

KEYS
Master key (black) ± The master key works in every lock.
For your Lexus dealer to make you a new key with built±in
transponder chip, your dealer will need it.
Subkey (gray) ± The subkey will not open the trunk, trunk
main switch and the glovebox.
Key number plate ± Keep the plate in a safe place such as
your wallet, not in the vehicle.
The master key and subkey each have a transponder chip in
their key head which is very important for the immobiliser
system function, 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 things locked in the trunk or glovebox when you
have your vehicle parked, leave the subkey with the attendant. Since
the doors and trunk lid can be locked without a key, you
should always carry a spare master key in case you
accidentally lock your keys inside the vehicle.
If you should lose your keys or if you need additional keys,
duplicates can be made by a Lexus dealer using the key
number.
We recommend you to write down the key number and keep
it in safe place.

KEYS AND DOORS
13
Since a transponder chip is not built in this flat key, you
cannot start the engine with this key. Use this key to
release the lock in case you accidentally lock your keys
inside the vehicle or trunk.
Insert your flat key in its key case as shown. We recommend
that you always carry this with you for emergency use. Do not
leave it in your vehicle.NOTICE

Do not let the key case become bent as the key may fall
out or become bent also.

The flat key is designed for emergency use only.

KEYS AND DOORS
14
When using a key containing a transponder chip, observe
the following precautions:

When sta rting 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.

KEYS AND DOORS
15


When starting the engine, do not use the key with
other transponder keys around (including keys of
other 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
taking off other transponder keys (including keys of
other vehicles) from the ring or while gripping or
covering them with your hand to start the engine.

KEYS AND DOORS
16

Do not bend the key grip.

Do not cover the key grip with any material that cuts
off electromagnetic waves.

Do not knock the key hard against other objects.

Do not leave the key exposed to high temperatures for
a long period, such as on the dashboard and hood
under the direct sunlight.

Do not put the key in water or wash it in an ultrasonic
washer.

Do not use the key with electromagnetic materials.ENGINE IMMOBILISER
SYSTEM

KEYS AND DOORS
17
The engine immobiliser system is a theft prevention
system. When you insert the key in the ignition switch, the
transponder chip in the key's head transmits an electronic
code to the vehicle. The engine will start, only when the
electronic code in the chip corresponds to the registered
ID code for the vehicle.
The system is automatically set when the key is removed from
the ignition switch. At this time, the security indicator light
at the bottom of the instrument cluster flashes. When you
insert the key in the ignition switch, the security indicator
light goes out and the system is canceled automatically, which
enables the engine to start.
For your Lexus 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 Lexus dealer can make for you. If you make your own duplicate key, you will not be able
to cancel the system or start the engine.
