Flat key
SV11020
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 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
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 immobilizer system is
automatically cancelled. (For details, see ªEngine immobilizer
systemªon page 12.) You can put the key case away then. You
cannot cancel the engine immobilizer 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.

ENGINE IMMOBILIZER SYSTEM
SV11007
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 or the flat key. However, there is a limit to the
number of additional keys your Lexus dealer can make for you. 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.)
If you make your own duplicate key, you will not be able
to cancel the system or start the engine.
