KEYS AND DOORS
10
1Master key (black) ± The master key works in
every l ock. For your Lexus dealer to make you
a new key with built±in transponder chip, your
dealer will need it.
2 Sub key (gray) ± The sub key will not open the
trunk, trunk main switch and the glove box.
3Key number plate ± Keep the plate in a safe
place such as your wallet, not in the vehicle.
The master key and sub key 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 glove box when
you have your vehicle parked, 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 you to write down the key number and
keep it in safe place.

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.
NOTICE
Do not let the key case become bent as the key
may fall out or become bent also.
The flat key is designed for emergency useonly.
