Using the mechanical key
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.
If the key cannot be inserted in a
lock cylinder, turn it over and re-
attempt to insert it. The mechanical
key with grooves on one side can
be inserted in one direction only.
After using the mechanical key,
store it in the electronic key. Carry
the mechanical 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. 5 9 1 )
■Card key (if equipped)
●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, press down the lock release button
using a pen tip etc. If it is still difficult to pull it out, use a coin etc.
●To store the mechanical key in the card
key, insert it while pressing the lock
release button.

●The card key is not waterproof.
■When required to leave the vehicle’s key with a parking attendant
Lock the glove box as circumstances demand. (→P. 4 2 1 )
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 by any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional using the key number
plate. (→P. 5 9 0 )
■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.
●If the battery cover is not installed and
the battery falls out or if the battery was
removed because the key got wet, rein-
stall the battery with the positive termi-
nal facing the Lexus emblem.

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 attach a sticker or anything else to the surface of the electronic key.

■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 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 autho-
rized 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.
