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 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 flat 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 immobilizer system is
automatically canceled. (For details, see “Engine immobilizer
system” on page 16.) 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.

NOTICE

Do not let the key case become bent as the key plate
may fall out or become bent also.
 The flat key is designed for emergency use only. So
do not use it regularly instead of other master keys.
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

proximity with other transponder keys (including the

remove the key once and then insert it again after
removing 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.

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 “Flat key” on page 13.)
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.
If you make your own duplicate key, you will not be able to
cancel the system or start the engine.
