■ 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 when the engine is
stopped.
●
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.126)
● 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.
● You can replace the battery by yourself
(

P.460). However, as there is a danger
that the electronic key may be damaged,
it is recommended that replacement is
carried out by your Lexus dealer.
● To avoid serious deterioration, do not
leave the electronic key within 3 ft. (1 m)
of the following electrical appliances that
produce a magnetic field:
• TVs
• Personal computers
• Cellular phones, cordless phones and
battery chargers
• Recharging cellular phones or cordless
phones
• Table lamps
• Induction cookers
● If the electronic key is near the vehicle for
longer than necessary, even if the smart
access system with push-button start is
not used, the key battery may become
depleted faster than normal. When not
using the smart access system with
push-button start, it is recommended not
to stay with the electronic key near the
vehicle longer than necessary.
