When required to leave the vehicle’s key with a parking attendant
Lock the glove box as circumstances demand. (P. 449)
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 such as your wallet, not in the vehicle. In the
event that a mechanical key is lost, a new key can be made at any authorized
Lexus dealer or repairer, or another duly qualified and equipped profes-
sional using the key number plate. (P. 629)
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 elec-
tronic key to emit radio waves that could interfere with the operation of the
aircraft.

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 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, caus-
ing 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.
When a vehicle key is lost
If the key remains lost, the risk of vehicle theft increases significantly. Visit
any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional immediately with all remaining electronic keys and
the card key that was provided with your vehicle.

Precautions for 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 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 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.

Battery-saving function
The battery-saving function will be activated in order to prevent the elec-
tronic key battery and the 12-volt battery from being discharged while the
vehicle is not in operation for a long time.
In the following situations, the smart entry & start system may take some
time to unlock the doors.
• The electronic key has been left in an area of approximately 2 m (6 ft.)
of the outside of the vehicle for 10 minutes or longer.
• The smart entry & start system has not been used for 5 days or longer.
If the smart entry & start system has not been used for 14 days or longer,
the doors cannot be unlocked at any doors except the driver’s door. In
this case, take hold of the driver’s door handle, or use the wireless
remote control or the mechanical key, to unlock the doors.

Note for the entry function
Even when the electronic key is within the effective range (detection
areas), the system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle,
near the ground, or in a high place when the doors are locked or
unlocked.
• The electronic key is on the instrument panel, luggage room, floor, or
in the door pockets or glove box when the hybrid system is started or
“POWER” switch modes are changed.
Do not leave the electronic key on top of the instrument panel or near the
door pockets when exiting the vehicle. Depending on the radio wave
reception conditions, it may be detected by the antenna outside the cabin
and the door will become lockable from the outside, possibly trapping
the electronic key inside the vehicle.
As long as the electronic key is within the effective range, the doors may
be locked or unlocked by anyone.
Even if the electronic key is not inside the vehicle, it may be possible to
start the hybrid system if the electronic key is near the window.
The doors may unlock if a large amount of water splashes on the door
handle, such as in the rain or in a car wash when the electronic key is
within the effective range. (The door will automatically be locked after
approximately 30 seconds if the doors are not opened and closed.)
If the wireless remote control is used to lock the doors when the elec-
tronic key is near the vehicle, there is a possibility that the door may not
be unlocked by the entry function. (Use the wireless remote control to
unlock the doors.)

CT200h_OM_OM76067E_(EE)
Note for locking the doors
Touching the door lock sensor while wearing gloves may delay or pre-
vent lock operation. Remove the gloves and touch the lock sensor again.
If the door handle becomes wet while the electronic key is within the
effective range, the door may lock and unlock repeatedly. Place the key
in a position 2 m (6 ft.) or more separate from the vehicle while the vehi-
cle is being washed. (Take care to ensure that the key is not stolen.)
If the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, a message may be shown on the multi-information
display and a buzzer will sound outside the vehicle. To turn off the
alarm, lock all the doors.
The lock sensor may not work properly if it comes into contact with ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again, or
use the lock sensor on the lower part of the door handle.
Fingernails may scrape against the door during operation of the door
handle. Be careful not to injure fingernails or damage the surface of the
door.
