KEYS
1Master keys (black) Ð These keys work in every lock.
For your Lexus dealer to make a new key with a
built±in transponder chip, your dealer will need one
of them.
2Valet key (gray) Ð This key will not open the glove
box.
3Key number plate Ð 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.

ENGINE IMMOBILIZER SYSTEM
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 ªFlat keyº on page 9.)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.
