Using the mechanical key
Take out the mechanical key.
The mechanical key can only be
inserted in one direction, as the
key only has grooves on one
side. If the key cannot 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 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. 458)
Card key
The mechanical key that is stored inside the card key should be used
only if a problem arises, such as when the 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.
To store the mechanical key in the
card key, insert it inside while
pressing the lock release button.

The card key is not waterproof.
When required to leave a key to the vehicle with a parking attendant
Turn the trunk opener main switch off and lock the glove box as circum-
stances demand. (P. 57, 324)
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 autho-
rized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional, using the key number plate. (P. 457)
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 air-
craft.
If the battery cover is not installed
and the battery falls out or if the bat-
tery was removed because the key
got wet, reinstall the battery with
the positive terminal facing the
Lexus emblem.

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 systems, glass top ranges, or medical electrical equipment,
such as low-frequency 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 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 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.
