KEYS
1Master keys (black) These keys work in every lock.
For your Lexus dealer to make you a new key with
builtin transponder chip, your dealer will need it.
2Sub 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 immobiliser system has been
placed in the head of the master and sub 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 sub 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 85. For locking the glove box, see page 70. For
locking the rear armrest door, see page 99.
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 immobiliser 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 immobiliser system is
automatically canceled. (For details, see “Engine immobiliser
system” on page 14.) 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 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.

may fall out or become bent also.
 The flat key is designed for emergency use only. So

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

stop soon after it starts.

KEYS AND DOORS

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

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.
