KEYS
11x503
1Master keys (black) The master keys work in every
lock. For your Lexus dealer to make you a new key
with a builtin transponder chip, your dealer will need
it.
2Valet key (gray) The valet key will not open the glove
box.
3 Key number plate Keep the plate in a safe place
such as your wallet, not in the vehicle.
A transponder chip for the engine immobilizer system has
been placed in the head of the master and valet 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 valet 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.

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 immobilizer 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
11x022b
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 immobilizer system is
automatically canceled. (For details, see “Engine immobilizer
system” on page 11.) You can put the key case away then. You
cannot cancel the engine immobilizer system if 10 seconds
have passed 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.

11L021-2
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.
11R055
When starting the engine, do not use the key in
proximity with other transponder keys (including
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 removing other
transponder keys (including keys of other vehicles)
from the ring or while gripping or covering them with
your hand to start the engine.

ENGINE IMMOBILIZER SYSTEM
11X514
The engine immobilizer 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
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.
The transponder chip of the flat key is in its key case. You can
cancel the engine immobilizer system using the flat key. (For
details, see “Flat key” on page 9.)

KEYS AND DOORS
12For 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.
