■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 your Lexus dealer using the key
number plate. (P. 5 74 )
■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
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 place the keys near objects that produce magnetic fields, such as TVs,
audio system, glass top ranges, or medical electrical equipment, such as low-fre-
quency 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 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 rap-
idly.
●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 or keys.
• The card key is scraped with a sharp object, such as a tip of mechanical pencil.
• The surface of the card key is wiped with thinners or benzene.

■Operation signals
A buzzer sounds and the emergency flashers flash to indicate that the doors have
been locked/unlocked. (Locked: Once; Unlocked: Twice)
■Conditions affecting operation
The smart access system with push-button start uses weak radio waves. In the fol-
lowing situations, the communication between the electronic key and the vehicle
may be affected, preventing the smart access system with push-button start. Wire-
less remote control, and immobilizer system from operating properly:
(Way of coping: P. 575)
●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 electrical noise
●When carrying a portable radio, cellular phone, cordless phone or other wire-
less communication devices
●When the electronic key is in contact with, or is covered by the following metal-
lic 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 other wireless keys (that emit radio waves) are 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 computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic content or metallic objects are attached to the rear
window

Unlock the doors using the wireless remote control and open one of the
doors.
If a door is not opened within 60 seconds after is pressed, the doors
will be locked again and the alarm will automatically be set.
In case that the alarm is triggered, immediately stop the alarm. (P. 1 0 1 )
■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 3 ft. (1 m) 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 function
(P. 53) or the mechanical key (P. 575)
■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 sys-
tem stops. (P. 4 9 )
●The battery becomes depleted even if the electronic key is not used because
the key always transmits radio waves. If the smart access system with push-but-
ton start or the wireless remote control does not operate, or the detection area
becomes smaller, the battery may be depleted. Replace the battery when nec-
essary. ( P. 4 9 4 )
●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
•Glass top ranges
• Table lamps

■To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get the
electronic key too close to the vehicle when operating the system from the outside
of the vehicle.
Depending on the position and holding condition of the electronic key, the key may
not be detected correctly and the system may not operate properly. (The alarm may
go off accidentally, or the door lock prevention may not function.)
■Note for the smart access system with push-button start
●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 near the ground or in a high place, or too close to the
rear bumper center when the trunk is unlocked.
• The electronic key is on the instrument panel, rear package tray or floor, or in
the glove box when the hybrid system is started or “POWER” switch modes
are changed.
●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 doors will automatically be locked after approximately 60 seconds
if the doors are not opened and closed.)
