Operation of each component
To take out the mechanical key:
Electronic keys: Slide the release lever
and take the key out.
Card key: Press the lock release button
and take the key out.
The mechanical key can only be
inserted in one direction, as the key only
has grooves on one side. If the key can-
not 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 mechan-
ical 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. 566)
■Panic mode
Using the mechanical key
When is pressed for longer than about one
second, an alarm will sound intermittently and
the vehicle lights will flash to deter any person
from trying to break into or damage your vehi-
cle.
To stop the alarm, press any button on the elec-
tronic key.

CT200h_OM_OM76215U_(U)3-1. Key information
■Card key (if equipped)
●The card key is not waterproof.
●The mechanical key that is st
ored inside the card key should be used only if a problem
arises, such as when the card 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 still difficult to pull it out, use a coin etc.
■When required to leave the vehicle’s key with a parking attendant
Lock the glove box as circumstances demand. ( P. 4 3 4 )
Remove the mechanical key for your own use and provide the attendant with the elec-
tronic key only.
■If you lose your mechanical keys
New genuine mechanical keys can be made by your Lexus dealer using another
mechanical key and the key number stamped on your key number plate. Keep the plate
in a safe place such as your wallet, not in the vehicle.
■When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not press any but-
tons on the electronic key while inside the airc raft 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.
●To store the mechanical key in the card key,
insert it while pressing the lock release button.
●If the battery cover is not installed and the bat-
tery falls out or if the battery was removed
because the key got wet, reinstall the battery
with the positive terminal facing the Lexus
emblem.

Operation of each component
■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 hybrid system
stops. ( P. 5 5 4 )
●As the electronic key always receives ra dio waves, the battery will become depleted
even if the electronic key is not used. The following symptoms indicate that the elec-
tronic key battery may be depleted. Replace the battery when necessary. ( P. 5 0 9 )
• The smart access system with push-button start or the wireless remote control does
not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
●To avoid serious deterioration, do not leave the electronic key within 3 ft. (1 m) 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
• Induction cookers
• Table lamps
■Replacing the battery
 P. 5 0 9
■Confirmation of the registered key number
The number of keys already registered to the vehicle can be confirmed. Ask your Lexus

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 temp
eratures 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 pr oduce magnetic fields, such as TVs, audio

quency therapy equipment.
■Carrying the electronic key on your person
Carry the electronic key 3.9 in. (10 cm) or mo re away from electric appliances that are
turned on. Radio waves emitted from electric appliances within 3. 9 in. (10 cm) of the
electronic key may interfere with the key, causing the key to not function properly.
■In case of a smart access system with push-button start malfunction or other key-
related problems
Take your vehicle with all the electronic keys provided with your vehicle, including the
card key, to your Lexus dealer.
■When an electronic key is lost
If the electronic key remains lost, the risk of vehicle theft increases significantly. Visit
your Lexus dealer immediately with all rema ining electronic keys and the card key that
were provided with your vehicle.
■Handling the card key (if equipped)
●Do not apply excess force when inserting th e 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 drin king water etc. is spilled on the key, immedi-
ately remove the battery cover and wipe the battery and terminals. (To remove the
battery cover, lightly grasp and pull it.) If the battery is corroded, have your Lexus
dealer 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 battery.
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 follow-
ing 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.

Operation of each component
■Alarms and warning messages
An alarm sounds and warning message displa ys shown on the multi-information display
are used to protect against unexpected acci dents or theft of the vehicle resulting from
erroneous operation. When a warning messag e is displayed, take appropriate measures
based on the displayed message. ( P. 5 4 2 )
When only an alarm sounds, circumstances and correction procedures are as follows.
■Battery-saving function
The battery-saving function will be activated in order to prevent the electronic key bat-
tery and the 12-volt battery from being discha rged while the vehicle is not in operation
for a long time.
●In the following situations, the smart access system with push-button start may take
some time to unlock the doors.
• The electronic key has been left in an area of approximately 6 ft. (2 m) of the outside
of the vehicle for 10 minutes or longer.
• The smart access system with push-butto n start has not been used for 5 days or
longer.
●If the smart access system with push-butto n start 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 us e the wireless remote control or the mechan-
ical key, to unlock the doors.
■Conditions affe cting operation
The smart access system with push-button star t, wireless remote control and immobilizer
system use weak radio waves. In the followi ng situations, the communication between the
electronic key and the vehicle may be affected, preventing the smart access system with
push-button start, wireless remote control and immobilizer system from operating prop-
erly. (Ways of coping: P. 566)
●When the electronic key battery is depleted
●Near a TV tower, electric powe r plant, gas station, radio station, large display, airport or
other facility that generates strong radio waves or electrical noise
●When carrying a portable radio, cellular ph one, cordless phone or other wireless com-
munication devices
