Operation of each component
SEQUOIA_OM_USA_OM0C035U
To take out the mechanical key,
push the release button and take
the key out.
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 reat-
tempt 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 ent ry function does not operate prop erly, you
will need the mechanical key. ( 507)
■Panic mode
■ When required to leave the vehicle’s key with a parking attendant
Lock the glove box as circumstances demand. ( P. 360)
Remove the mechanical key for your own use and provide the attendant with
the electronic key only.
■ If you lose your keys
New genuine key can be made by your Toyota dealer.
The following are necessary when making new keys.
Mechanical key:
The key number for the mechanical key stamped on the number pla te and the
other key.
Key:
The key number for key stamped on the key number plate.
Keep the plates in a safe place such as your wallet, not in the vehicle.
There are key number plates for the mechanical key and key resp ectively.
When storing them, keep them in a safe place in a manner to distinguish one
from the other (such as markings, etc.).

When riding in an aircraft
When bringing a key with wireless remote control function onto an aircraft,
make sure you do not press any buttons on the key while inside the aircraft
cabin. If you are carrying the key in your bag, etc., ensure th at the buttons are
not likely to be pressed accidentally. Pressing a button may cause the key to
emit radio waves that could interfere with the operation of the aircraft.
■ Conditions affecting operation
P. 131
■ Key battery depletion
●The standard battery life is 1 to 2 years.
● If the battery becomes low, an alarm will sound in the cabin wh en the engine
stops. ( P. 488)
● As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms indi-
cate that the electronic key battery may be depleted. Replace the battery
when necessary. ( P. 446)
• The smart key system or the wirel ess remote control does not oper-
ate.
• 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 1 m
(3 ft.) of the following electrical appliances that produce a m agnetic 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. 446
■ Confirmation of the registered key number
The number of keys already registered to the vehicle can be confirmed. Ask
your Toyota dealer for details.
■ Customization
Settings (e.g. wireless remote control system) can be changed.

Operation of each component
SEQUOIA_OM_USA_OM0C035U■
Conditions affecting operation
The smart key system uses weak radio waves. In the following si tuations, the
communication between the electronic key and the vehicle may be affected,
preventing the smart key system, wireless remote control and en gine immobi-
lizer system from operating properly. (Ways of coping: P. 507)
● When the electronic key battery is depleted
● Near a TV tower, electric power plant, gas station, radio stati on, large dis-
play, airport or other facility that generates strong radio wav es or electrical
noise
● When carrying a portable radio, cellular phone, cordless phone or other
wireless communication device
● When the electronic key is in contact with, or is covered by the following
metallic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
• Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
● When multiple electronic keys are in the vicinity
● When other wireless 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 with a metallic content or metallic objects are attached to the
back window
● When the electronic key is placed near a battery charger or ele ctronic
devices

1323-2. Opening, closing and locking the doors
SEQUOIA_OM_USA_OM0C035U■
Note for the entry function
●Even when the electronic key is within the effective range (det ection areas),
the system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle, near
the ground, or in a high place when the doors are locked or unl ocked.
• The electronic key is on the instrument panel or floor, or in the console
box or glove box when the engine is started or engine switch mo des are
changed.
● Do not leave the electronic key on top of the instrument panel or near the
door pockets when exiting the vehicle. Depending on the radio w ave recep-
tion conditions, it may be detected by the antenna outside the cabin and the
door will become lockable from the outside, possibly trapping the electronic
key inside the vehicle.
● As long as the electronic key is within the effective range, th e doors may be
locked or unlocked by anyone. However, only the doors detecting the elec-
tronic key can be used to unlock the vehicle.
● Even if the electronic key is not inside the vehicle, it may be possible to start
the engine if the electronic key is near the window.
● The doors may unlock or lock if a large amount of water splashe s on the
door handle, such as in the rain or in a car wash, when the electronic key is
within the effective range. (The doors will automatically be lo cked after
approximately 60 seconds if the doors are not opened and closed.)
● If the wireless remote control is used to lock the doors when t he electronic
key is near the vehicle, there is a possibility that the door m ay not be
unlocked by the entry function. (Use the wireless remote contro l to unlock
the doors.)
● Touching the door lock or unlock sensor while wearing gloves ma y prevent
lock or unlock operation. Remove the gloves and touch the lock sensor
again.
● When the lock operation is performed using the lock sensor, rec ognition sig-
nals will be shown up to two consecutive times. After this, no recognition
signals will be given.
● If the door handle becomes wet while the electronic key is with in the effec-
tive range, the door may lock and unlock repeatedly. In this ca se, follow the
following correction procedures to wash the vehicle:
• Place the electronic key in a location 6 ft. (2 m) or more awa y from the
vehicle. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the s mart key
system. ( P. 130)
● If the electronic key is inside the vehicle and a door handle b ecomes wet
during a car wash, a message may be shown on the multi-informat ion dis-
play and a buzzer will sound outside the vehicle. To turn off t he alarm, lock
all the doors.

2164-2. Driving procedures
SEQUOIA_OM_USA_OM0C035U
