Electronic keys
• Operating the smart access system with push-button start ( P.111)
• Operating the wireless remote control  function ( P.98)
Mechanical keys
Key number plate
Card key (electronic key) (if 
equipped)
Operating the smart access system with 
push-button start ( P.111)
■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 lock release button 
using a pen tip etc. If it is still difficult to 
pull it out, use a coin etc.
●To store the mechanical key in the card 
key, insert it while pressing the lock 
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 about a year 
and a half.)
●If the battery becomes low, an alarm will 
sound in the cabin and a message will be 
shown on the multi-information display

Before driving
●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.113)
●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.
• 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.
●To avoid serious deterioration, do not 
leave the electronic key 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.403
■Confirmation of the number of regis-
tered keys
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 been 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 a long period of time.
●Do not get the keys wet or wash them 
in an ultrasonic washer etc.
●Do not attach metallic or magnetic 
materials to the keys or place the keys 
close to such materials.
●Do not disassemble the keys.
●Do not attach a sticker or anything else 
to the surface of the electronic key.
●Do not place the keys near objects that 
produce magnetic fields, such as TVs, 
audio systems and induction cookers, 
or medical electrical equipment, such 
as low-frequency therapy equipment.
■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.
