KEYS AND DOORS

KEYS
1Master keys (black) — These keys work in every lock.
For your Lexus dealer to make a new key with a
builtin transponder chip, your dealer will need one
of them.
2Valet key (gray) — This key will not open the glove
box and rear armrest door in the rear seat.
3Key number plate — Keep the plate in a safe place
such as your wallet, not in the vehicle.
A transponder chip for engine immobilizer system has been
placed in the head of the master and valet 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 trunk or glove box when using
valet parking, leave the valet key with the attendant.
The trunk lid can be opened using a loop of wire in the trunk
even with the trunk lid opener main switch in the glove box
turned off.
When keeping items in the trunk, be sure to turn off
the trunk lid opener main switch and lock the glove box and rear
armrest door. To turn off the main switch in the glove box, see
page xcv. For locking the glove box, see page lxxviii. For
locking the rear armrest door, see page lxxxviii.
Since the doors can be locked without a key, you should always
carry the flat key or 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.

KEYS AND DOORS

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 engine immobilizer system has been
placed in the key case of the flat key. This chip is needed to
enable 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 immobilizer system is
automatically canceled. (For details, see “Engine immobilizer
system” on page xv.) You can put the key case away then. You
cannot cancel the engine immobilizer system if 10 seconds
have past after you ins erted 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 20 seconds after the security
indicator light goes out. You cannot start the engine if 20
seconds have past 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. So
do not use it regularly instead of other master keys.
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
xiv
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
removing 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 and 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.

ENGINE IMMOBILIZER SYSTEM
Type A
Type B 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.
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.
