3-1.Key information
The following keys are provided with
the vehicle.
Electronic keys
• Operating the smart access system with push-button start ( P.117)
• 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.117)
■Card key (if equipped)
●The card key is not waterproof.
●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 it is difficult to take out the mechanical
key, push down the release button using a
pen tip etc. If it is still difficult to pull it out,
use a coin etc. (
P.108)
●To store the mechanical key in the card
key, insert it while pressing the release
button.
●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.
■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 from one year
to one year and a half.)
●If the battery becomes low, an alarm will
sound in the cabin when the engine
is stopped.
●Electronic keys that will not be used for

long periods of time can be set to the bat-
tery-saving mode in advance. (P.119)
●As the electronic ke y 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.330)
• 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.330). However, as there is a danger
that the electronic key may be damaged, it
is recommended that replacement be car-
ried out by your Lexus dealer.
●To avoid serious deterioration, do not
leave the electronic ke y within 3 ft. (1 m)
of the following electr ical 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
■Replacing the battery
 P.330
■Confirmation of the registered key
number
The number of keys already registered to
the vehicle can be confirmed. Ask your
Lexus dealer for details.
■If “A New Key has been Registered
Contact Your Dealer for Details” is
shown on the multi-information display
This message will be displayed each time
the driver’s door is opened when the doors
are unlocked from the outside for approxi-
mately 10 days after a new electronic key
has been registered.
If this message is disp layed but you have not
had a new electronic key registered, ask your Lexus dealer to check if an unknown
electronic key (other than those in your
possession) has be
en registered.
NOTICE
■To prevent key damage
●Do not drop the keys, subject them to
strong shocks or bend them.
●Do not expose the keys to high tem-
peratures for long periods of time.

receive medical attent ion with the keys
on your person.
■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
