1Master keys (black) ± These keys work in every lock.
For your Lexus dealer to make you a new key with
built±in transponder chip, your dealer will need an
original key to program the new one.
2Sub key (gray) ± The sub key will not open the trunk
and 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 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.
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.
We recommend writing down the key number and storing it in
a safe place.

Since 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
SV11011
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 cancelled. (For details, see ºEngine immobiliser
systemºon 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 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.
