1-1. Key information

Before driving
IS250/220d/200d_EE
Using the mechanical key
Take out the mechanical key.
The mechanical key can only be
inserted in one direction, as the
key only has grooves on one
side. If the key cannot be
inserted in a lock cylinder, turn
it over and re-attempt to insert
it.
After using the mechanical key,
store it in the electronic key.
Carry the mechanical key
together with the electronic key.
If the electronic key battery is
depleted or the entry function
does not operate properly, you
will need the mechanical key.
(P. 516)
Card key
The mechanical key that is stored inside the card key should be used
only if a problem arises, such as when the key does not operate properly.
If it is difficult to take out the mechanical key, push down the lock
release button using a pen tip etc. If it is difficult to pull it out, use a coin
etc.

34
1-1. Key information
IS250/220d/200d_EE
The card key is not waterproof.
When required to leave a key to the vehicle with a parking attendant
Turn the trunk opener main switch off and lock the glove box as circum-
stances demand. (P. 60, 356)
Remove the mechanical key for your own use and provide the attendant
with the electronic key only.
Key number plate
Keep the plate in a safe place, not in the vehicle. In the event that a mechan-
ical key is lost, a new key can be made by any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional, using the key
number plate. (P. 515)
When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not
press any buttons on the electronic key while inside the aircraft cabin. If you
are carrying an electronic key in your bag etc, ensure that the buttons are not
likely to be pressed accidentally. Pressing a button may cause the electronic
key to emit radio waves that could interfere with the operation of the air-
craft.
To store the mechanical key in the
card key, insert it inside while
pressing the lock release button.
If the battery was removed, reinstall
the battery with the positive termi-
nal facing the Lexus emblem.

NOTICE
To prevent key damage
Observe the following.
Do not drop the keys, subject them to strong shocks or bend them.
Do not expose the keys to high temperatures for a long period of time.
Do not get the keys wet or wash them in an ultrasonic washer etc.
Do not attach metallic or magnetic materials to the keys or place the keys
close to such materials.
Do not disassemble the keys.
Do not attach stickers that contain materials that block radio waves, such
as metallic materials, to the key.
Do not place the keys near objects that produce magnetic fields, such as
TVs, audio systems, glass top ranges, or medical electrical equipment,
such as low-frequency therapy equipment.
Precautions for handling the card keys
Do not apply excess force when inserting the mechanical key to the card
key. Doing so may damage the card key.
If the battery or card key terminals get wet, the battery may corrode and
the card key may stop working.
If the key is dropped into water, or if drinking water etc. is spilled on the
key, immediately remove the battery cover and wipe the battery and ter-
minals. (To remove the battery cover, lightly grasp it and pull.) If the bat-
tery is corroded, have any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional, replace the battery.
Do not crush the battery cover or use a screwdriver to remove the battery
cover. Forcibly removing the battery cover may bend or damage the key.
If the battery cover is frequently removed, the battery cover may become
loose.
When installing the battery, make sure to check the direction of the bat-
tery.
Installing the battery in the wrong direction may cause the battery to
deplete rapidly.

1-2. Opening, closing and locking the doors and trunk
IS250/220d/200d_EE
Operation signals
Doors: The emergency flashers flash to indicate that the doors have been
locked/unlocked. (Locked: Once; Unlocked: Twice)
Windows and moon roof: A buzzer sounds to indicate that the windows and
moon roof are operating.
Conditions affecting operation
The smart entry & start system uses weak radio waves. In the following sit-
uations, the communication between the electronic key and the vehicle may
be affected, preventing the smart entry & start system and wireless remote
control from operating properly:
(Ways of coping: P. 516)
When the electronic key battery is depleted
Near a TV tower, electric power plant, gas station, radio station, large
display, airport or other facility that generates strong radio waves or elec-
trical noise
When carrying a portable radio, cellular phone, cordless phone or other
wireless communication devices
When the electronic key is in contact with, or is covered by the follow-
ing metallic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
• Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
When multiple electronic keys are in the vicinity
When another wireless key (that emits radio waves) is being used nearby
When carrying or using the electronic key together with the following
devices that emit radio waves
• Another vehicle's electronic key or a wireless key that emits radio
waves
• Personal computer or personal digital assistant (PDA)
• Digital audio player
• Portable game system
If window tint with a metallic content or metallic objects are attached to
the rear window

1-2. Opening, closing and locking the doors and trunk
IS250/220d/200d_EE
Battery-saving function
In the following circumstances, the entry function is disabled in order to
prevent the vehicle and electronic key batteries from discharging.
When the entry function has not been used for a month or more
When the electronic key has been left within approximately 1 m (3 ft.) of
the vehicle for 10 minutes or more
The system will resume operation when
The vehicle is locked using the door handle lock switch.
The vehicle is locked/unlocked using the wireless remote control func-
tion.
(P. 55)
The vehicle is locked/unlocked using the mechanical key. (P. 516)
Electronic key battery depletion
The standard battery life is 1 to 2 years. (The card key battery life is
about a year and a half.)
If the battery becomes low, an alarm will sound in the cabin when the
engine stops. (P. 481)
The battery becomes depleted even if the electronic key is not used
because the key always receives radio waves. If the smart entry & start
system or the wireless remote control does not operate, or the detection
area becomes smaller, the battery may be depleted. Replace the battery
when necessary.
(P. 431)
To avoid serious deterioration, do not leave the electronic key within 1 m
(3 ft.) of the following electrical appliances that produce a magnetic
field.
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Glass top ranges
• Table lamps
