KEYS
1Master keys (black) These keys work in every lock.
For your Lexus dealer to make a new key with builtin
transponder chip, your dealer will need one of them.
2Sub key (gray) This key will not open the glove box.
3Key number plate Keep the plate in a safe place
such as your wallet, not in the vehicle.
A transponder chip for the engine immobiliser system has been
placed in the head of the master and sub keys. These chips
are required for 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 and back door 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 writing down the key number and storing it in
a safe place.

Flat key
As a transponder chip is built in its key case, you can start
the engine with this key.
The flat key works in every lock.
A transponder chip for the engine immobiliser system has been
placed in the key case of the flat key. This chip is required for
the system to function correctly, so be careful not to lose this
key. If you make your own duplicate key, you will not be able
to cancel the system or start the engine.
Insert your key plate 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.
Starting the engine using a flat key
1. Remove the key plate from the key case.
2. Insert the key plate into the ignition switch. The indicator
light keeps flashing.
3. Bring the key case closer to the ignition switch within 10
seconds as indicated by the arrow head. The indicator light
goes out. This means the engine immobiliser system is
automatically canceled. (For details, see “Engine immobiliser
system” on page 12.) You can put the key case away then. You
cannot cancel the engine immobiliser system if 10 seconds
have past after you inserted the key plate. You need to remove
the key plate from the ignition switch and try it again from the
step 2.
4. Start the engine within 60 seconds after the security
indicator light goes out. You cannot start the engine if 60
seconds have passed after the security indicator went off. You
need to remove the key plate from the ignition switch and try
it again from the step 2.

NOTICE
Do not let the key case become bent as the key plate
may fall out or become bent also.
 The flat key is designed for emergency use only.
When using a key containing a transponder 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. Doing so may prevent
the engine from starting, or may cause the engine to
stop soon after it starts.

KEYS AND DOORS
11
When starting the engine, do not use the key in
proximity with other transponder keys (including the
flat key and keys of other vehicles), and do not press
other key plates against the key grip. Doing so may
prevent the engine from starting, or may cause the
engine to stop soon after it starts. If this happens,
remove the key once and then insert it again after
taking off other transponder keys (including the flat
key and keys of other vehicles) from the ring or while
gripping or covering them with your hand to start the
engine. Do not bend the key grip or flat key.
 Do not cover the key grip or flat key with any material
that cuts off electromagnetic waves.
 Do not knock the key or flat key hard against other
objects.
 Do not leave the key or flat key exposed to high
temperatures for a long period, such as on the
dashboard or hood under direct sunlight.
 Do not put the key or flat key in water or wash it in an
ultrasonic washer.
 Do not use the key or flat key with electromagnetic
materials.
