KEYS
11L025-3
1
Master key (black) The master key works in every lock.
For your Lexus dealer to make you a new key with builtin
transponder chip, your dealer will need it.
2
Subkey (gray) The subkey will not open the trunk, trunk
main switch and the glovebox.
3
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.
You should also put a copy of the key number with your important
papers.
11L003
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.

KEYS AND DOORS

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

NOTICE
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. Otherwise the engine may not start, or may stop
soon after it starts.
11L022-2
When starting the engine, do not use the key in contact with
another transponder key (including keys of other vehicles)
and do not press another key plate against the key grip.
Otherwise the engine may not start, or may stop soon after it

11L023-3
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
11L0243
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 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
Lexus dealer can make for you.

KEYS AND DOORS
11 If you make your own duplicate key, you will not be able to cancel
the system or start the engine.
