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 aircraft.
NOTICE
To prevent key damage
Do not drop the keys, subject them to strong shocks or bend them.
Do not expose the keys to high temperatures for long periods 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 a sticker or anything else to the surface of the electronic key.
Do not place the keys near objects that produce magnetic fields, such as
TVs, audio systems and induction cookers, or medical electrical equip-
ment, such as low-frequency therapy equipment.
Carrying the electronic key on your person
Carry the electronic key 10 cm (3.9 in.) or more away from electric appli-
ances that are turned on. Radio waves emitted from electric appliances
within 10 cm (3.9 in.) of the electronic key may interfere with the key,
causing the key to not function properly.
In case of a smart entry & start system malfunction or other key-related
problems
Take your vehicle with all the electronic keys provided with your vehicle,
including the card key, to any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.

NOTICE
When an electronic key is lost
If the electronic key remains lost, the risk of vehicle theft increases signifi-
cantly. Visit any authorized Lexus dealer or repairer, or another duly quali-
fied and equipped professional immediately with all remaining electronic
keys and the card key that was provided with your vehicle.
Handling the card key
Do not apply excess force when inserting the mechanical key into the card
key. Doing so may damage the card key.
If the battery or card key terminals get wet, the battery may corrode.
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 and pull it.) 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.
The surface of the card key may be damaged, or its coating may peel off
in the following situations:
• The card key is carried together with hard objects, such as coins and
keys.
• The card key is scraped with a sharp object, such as the tip of a
mechanical pencil.
• The surface of the card key is wiped with thinner or benzene.
