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. 716)
■
Card key (if equipped)
●
The card key is not waterproof.
●
The mechanical key that is stored 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.
Using the mechanical key
●
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.

■
When required to leave the vehicle’s key with a parking attendant
Lock the glove box as circumstances demand. (
P. 569)
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 any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repairer 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 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.
■
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. 689)
●
As the electronic key always receives radio 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. 636)
• The smart entry & start system 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 1 m (3 ft.) 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. 636
■
Confirmation of the registered key number
The number of keys already registered to the vehicle can be confirmed. Ask any autho-
rized Lexus retailer or Lexus authorized repairer, or any reliable repairer for details.
■
If a wrong key is used
The key cylinder rotates freely to isolate inside mechanism.

■
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.
●

quency therapy equipment.
■
Carrying the electronic key on your person
Carry the electronic key 10 cm (3.9 in.) or more away from electric appliances 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 retailer or Lexus authorized repairer, or any reliable
repairer.
■
When an electronic key is lost
If the electronic key remains lost, the risk of vehicle theft increases significantly. Visit
any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer
immediately with all remaining 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 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, 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 any authorized
Lexus retailer or Lexus authorized repairer, or any reliable repairer replace the bat-
tery.
●
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.

open unexpectedly while driving and hit near-by objects or luggage in the luggage
compartment may be thrown out, causing an accident.
●
Do not allow children to play in the luggage compartment.
If a child is accidentally locked in the luggage compartment, they could have heat
exhaustion or other injuries.

WARNING
■
Operating the back door
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in death or serious
injury.
●
Remove any heavy loads, such as snow and ice, from the back door before opening it.
Failure to do so may cause the back door to suddenly shut again after it is opened.
●
When opening or closing the back door, thoroughly check to make sure the sur-
rounding area is safe.
●
If anyone is in the vicinity, make sure they are safe and let them know that the back
door is about to open or close.
●
Use caution when opening or closing the back door in windy weather as it may move
abruptly in strong wind.
●
Do not pull on the back door damper stay to close the back door, and do not hang on
the back door damper stay.
Doing so may cause hands to be caught or the back door damper stay to break, caus-
ing an accident.
●
If a bicycle carrier or similar heavy object is attached to the back door, it may sud-
denly shut again after being opened, causing someone’s hands, head or neck to be
caught and injured. When installing an accessory part to the back door, using a genu-
ine Lexus part is recommended.
●
The back door may suddenly shut if it is not
opened fully. It is more difficult to open or
close the back door on an incline than on a
level surface, so beware of the back door
unexpectedly opening or closing by itself.
Make sure that the back door is fully open and
secure before using the luggage compart-
ment.
●
When closing the back door, take extra care
to prevent your fingers etc. from being
caught.
●
When closing the back door, make sure to
press it lightly on its outer surface. If the back
door handle is used to fully close the back
door, it may result in hands or arms being
caught.

Do not touch the damper stay rod with gloves
or other fabric items.
●
Do not attach any accessories other than
genuine Lexus parts to the back door.
