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.

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

doors from being unlocked. In this case, return the door handle to the
original position and check that the doors unlock before pulling the door
handle again.
