KEYS AND DOORS

KEYS
Vehicles with power back door system
Vehicles without power back door system
1Master keys (black) — These keys work in every lock.
For your Lexus dealer to make a new key with a
builtin transponder chip, your dealer will need one
of them.
2Valet key (gray) — This key will not open 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 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.

KEYS AND DOORS

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.

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.

THEFT DETERRENT SYSTEM
To deter theft of the vehicle, this system is designed to
sound an alarm if any of the doors or hood is forcibly
unlocked or the battery terminal is disconnected and then
reconnected while the vehicle is locked.
The alarm blows the horn intermittently and flashes the
headlights, tail lights and turn signal lights.
Further more when the interior light switch is in the “DOOR”
position, the interior light turns on.
 Security indicator light
Setting the system
1. Turn the ignition key to the “LOCK” position and
remove it.
The engine immobilizer system causes the indicator light to
flash.
2. Close and lock all the doors and hood using an ignition
key or wireless remote control.
The flashing indicator light will remain on when all the doors
and hood are closed and locked.
3. After 30 seconds, the indicator starts flashing and the
system is set.

STARTING AND DRIVING
386“ACC” — Accessories such as the radio operate, but the
engine is off.
If you leave the key in the “ACC” or “LOCK” position and open
the driver’s door, a buzzer will remind you to remove the key.
“LOCK” —
Engine is off and the steering wheel is locked.
The ignition key can be removed only at this position.
You must push in the key to turn it from “ACC” to the “LOCK”
position. The selector lever must be put in the “P” position
before turning the key to the “LOCK” position.
Once you remove the key, the engine immobilizer system is
automatically set. See “Engine immobilizer system” on page
16.
When starting the engine, the key may seem stuck at the
“LOCK” position. To free it, first be sure the key is pushed all
the way in, and then rock the steering wheel slightly while
turning the key gently.
If, in an emergency, you must turn the engine off while the
vehicle is moving, turn the key only to “ACC”.
If is not a malfunction if the needles on all meters and gauges
move slightly when the key is turned tp the “ACC”, “ON” or
“START” position.

IF YOUR ENGINE STALLS WHILEDRIVING
If your engine stalls while driving...
1. Reduce your speed gradually, keeping a straight line. Move
cautiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Turn the ignition key to “ACC” or “LOCK”, and try starting the
engine again.
If the engine will not start, see “If your vehicle will not start”\
.
CAUTION
If the engine is not running, the power assist for the
brakes and steering will not work, so steering and
braking will be much harder than usual.
IF YOUR VEHICLE WILL NOT START
(a) Simple checks
Before making these checks, make sure you have followed the
correct starting procedure instructions in “How to start the
engine” on page 388 and that you have sufficient fuel. Since
your vehicle is equipped with the engine immobilizer system,
also check whether the other keys will start the engine. If they
work, your key may be broken. Have the key checked at your
Lexus dealer. If none of your keys work, there may be a
malfunction in the immobilizer system. Call your Lexus dealer.
See “Keys” on page 12.
If the engine is not turning over or is turning over too
slowly —
1. Check that the battery terminals are tight and clean.
2. If the battery terminals are O.K., switch on the interior light.
3. If the light is out, dim or goes out when the starter is cranked,
the battery is discharged. You may try jump starting. See “(c)
Jump starting” for further instruction.
If the light is O.K., but the engine still will not start, it needs
adjustment or repair. Call a Lexus dealer, Roadside
Assistance or Customer Service. (See “Foreword”.)

IN CASE OF AN EMERGENCY

3Push down the shift lock override button. You can shift out
of “P” position only while pushing the button.
4Shift into “N” position.
Insert the cover. Start the engine. For your safety, keep
the brake pedal depressed.
Be sure to have the system checked by your Lexus dealer as
soon as possible.
IF YOU LOSE YOUR KEYS OR LOCK YOURSELF OUT
You can purchase a new key at your Lexus dealer if you
can give them the key number and master key.
Even if you lose only one key, contact your Lexus dealer to
make a new key. If you lose all your master keys, you cannot
make new keys; the whole engine immobilizer system must be
replaced.
See the suggestion given in “Keys” on page 12.
You can use the wireless remote control system with the new
key. Contact your Lexus dealer for detailed information.
If your keys are locked in the vehicle and you cannot get a
duplicate, many Lexus dealers can still open the door for you
using special tools. If you must break a window to get in, we
suggest breaking the smallest side window because it is the
least expensive to replace. Be extremely cautious to avoid
glass cuts.
