923-1. Key information
3-1.Key information
The following keys are provided
with the vehicle.Electronic keys
• Operating the smart key system ( P.102)
• Operating the wireless remote control function ( P. 9 3 )
Mechanical keys
Key number plate
■When riding in an aircraft
When bringing an electronic key
onto an aircraft, make sure you do
not press any buttons on the elec-
tronic key while inside the aircraft
cabin. If you are carrying an elec-
tronic key in your bag, etc., ensure
that the buttons are not likely to be
pressed accidentally. Pressing a
button may cause the electronic key
to emit radio waves that could inter-
fere with the oper ation of the air-
craft.
■Electronic key battery depletion
●The standard battery life is 1 to 2
years.
●If the battery becomes low, an
alarm will sound in the cabin and a
message will be s hown on the
multi-information display 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 bat-
tery-saving mode. ( P.104)
●As the electronic key always
receives radio waves, the battery
will become depleted even if the
electronic key is not used. The fol-
lowing symptoms indicate that the
electronic key battery may be
depleted. Replace the battery
when necessary. ( P.304)
• The smart key system or the wire-
less remote contro l does not oper-
ate.
• The detection area becomes
smaller.
• The LED indicator on the key sur- face does not turn on.
●To avoid serious deterioration, do
not leave the electronic key within
3 ft. (1 m) of the following electri-
cal 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 key system is not
operated, the key battery may
become depleted faster than nor-
mal.
■Replacing the battery
 P.304
■The electronic key function is
suspended when
The electronic key function may be
suspended when the electronic key
is kept unmoved in a same location
for a certain period, such as it is left
on a same place. This is to reduce
battery consumption. The function
will be restored automatically when
the electronic key is moved, such as

943-1. Key information
will sound intermittently and the
vehicle lights will flash to deter any
person from trying to break into or
damage your vehicle.
To stop the alarm, press any button
on the wireless re mote control.
To take out the mechanical key,
push the release button and

The mechanical key can only be
inserted in one direction, as the
key only has grooves on one
side. If the key cannot be
inserted in a lock cylinder, turn it
over and re-attempt to insert it.
After using the mechanical key,
store it in the electronic key.
Carry the mechanical key
together with the electronic key.
If the electronic key battery is
depleted or the entry function
does not operate properly, you
will need the mechanical key.

in advance.
■Conditions affecting operation
The smart key system uses weak
radio waves. In the following situa-
tions, the communication between
the electronic key and the vehicle
may be affected, preventing the
smart key system, wireless remote
control and engine immobilizer sys-
tem from operating properly.
●When the electronic key battery is
depleted
●Near a TV tower, electric power
plant, gas station , radio station,
large display, airpo rt or other facil-
ity that generates strong radio
waves or electrical noise
●When carrying a portable radio,
cellular phone, cordless phone or
other wireless communication
device
●When the electronic key is in con-
tact with, or is c overed by the fol-
lowing metallic objects
• Cards to which aluminum foil is
attached
• Cigarette boxes that have alumi-
num foil inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When other wirel ess keys (that
emit radio waves) are being used
nearby
●When carrying the electronic key
together with the following devices
that emit radio waves
• Another vehicle’s electronic key or a wireless key that emits radio
waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint wit h a metallic con-
tent or metallic objects are
attached to the rear window
●When the electronic key is placed
near a battery charger or elec-
tronic devices
●When the vehicle is parked in a
pay parking spot where radio
waves are emitted
If the doors cannot be
locked/unlocked using the smart key
system, lock/unlock the doors by
performing any of the following:
●Bring the electronic key close to
either front door handle and oper-

●Setting the electronic key to bat-
tery-saving mode helps to reduce
key battery depletion. (P.104)
■To operate the system properly
Make sure to carry the electronic
key when operating the system. Do
not get the electronic key too close
to the vehicle when operating the

WARNING
■Caution regarding interfer-
ence with electronic devices
●People with implantable car-
diac pacemakers, cardiac
resynchronization ther-
apy-pacemakers or implantable
cardioverter defibrillators should
keep away from the smart key
system antennas. ( P.102)
The radio waves may affect the
operation of such devices. If
necessary, the entry function
can be disabled. Ask your Toy-
ota dealer for details, such as
the frequency of radio waves
and timing of the emitted radio
waves. Then, consult your doc-
tor to see if you should disable
the entry function.
●Users of any electrical medical
device other than implantable
cardiac pacemakers, cardiac
resynchronization ther-
apy-pacemakers or implantable
cardioverter defibrillators should
consult the manufacturer of the
device for information about its
operation under the influence of
radio waves.
Radio waves could have unex-
pected effects on the operation
of such medical devices.
Ask your Toyota dealer for details
on disabling the entry function.
