• Operating the wireless remote control function
Mechanical keys
Key number plate
Card key (electronic key) (if
equipped)
Operating the smart access system with
push-button start ( P.124)
■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.
●To reduce key battery depletion when the
electronic key is to not be used for long
periods of time, set the electronic key to
the battery-saving mode. ( P.125)
●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. ( P.368)
• 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.
