Operating the smart access system with
push-button start ( P.126)
■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 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 terminal
facing the Lexus emblem.
●The card key is not waterproof.
■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 acci-
dentally. Pressing a button may cause the
electronic key to emit radio waves that
could interfere with the operation of the air-
craft.
■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 wh en the hybrid sys-
tem stops.
●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 electronic key battery may be
depleted. Replace the battery when nec-
essary.
• The smart access system with push-but- ton start or the wireless remote control
does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.

■Carrying the electronic key on your
person
Carry the electronic key 3.9 in. (10 cm)
or more away from electric appliances
that are turned on. Radio waves emitted
from electric applianc es within 3.9 in. (10
cm) of the electronic key may interfere
with the key, causing the key to not func-
tion properly.

push-button start malfunction or
other key related problems
 P.410
■When an electronic key is lost
 P.409
■Handling the card key

cover and wipe the battery and termi-
nals. (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 rapidly.
●The surface of the card key may be
damaged, or its coating may peel off in
the following situations:
• The card key is ca rried 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
