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.
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.

NOTICE
Precautions for handling the card key
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 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 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.
