To take out the mechanical key,
slide the release lever 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 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 bat-
tery is depleted or the entry function does not operate properly, you will
need the mechanical key. (

If you lose your mechanical keys
New genuine mechanical keys can be made by your Toyota dealer using
another mechanical key and the key number stamped on your key number
plate. Keep the plate in a safe place such as your wallet, not in the vehicle.

■

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 accidentally. Pressing a button may cause the electronic
key to emit radio waves that could interfere with the operation of the aircraft.

Using the mechanical key

Release

When

is pressed for longer than

about one second, an alarm 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
electronic key.

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 displayed on the multi-information display when the hybrid system
stops.

●

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. 635)

• The smart key system 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. 635). However, as there is a

danger that the electronic key may be damaged, it is recommended that
replacement is carried out by your Toyota 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
• Table lamps
• Induction cookers

taking the key out of the vehicle, etc., a message that prompts the user to
confirm the state of the electronic key or power switch mode may be shown
on the multi-information display. In those cases, follow the instructions on the
display immediately.

■

If “Key Battery Low Replace Key Battery” is displayed on the multi-infor-
mation display
The electronic key has a low battery. Replace the electronic key battery.

Confirmation of the registered key number
The number of keys already registered to the vehicle can be confirmed. Ask
your Toyota dealer.

■

If “A New Key has been Registered Contact Your Dealer for Details” is
displayed 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 approximately 10 days after a
new electronic key has been registered.
If this message is displayed but you have not had a new electronic key regis-
tered, ask your Toyota 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 temperatures for long periods 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.

●

Do not place the keys near medical electrical equipment such as low-fre-
quency therapy equipment or microwave therapy equipment, and do not
receive medical attention 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 appli-
ances that are turned on. Radio waves emitted from electric appliances
within 3.9 in. (10 cm) of the electronic key may interfere with the key, caus-
ing the key to not function properly.

■

In case of a smart key system malfunction or other key-related prob-
lems
Take your vehicle with all the electronic keys provided with your vehicle to
your Toyota dealer.

■

When an electronic key is lost
If the electronic key remains lost, the risk of vehicle theft increases signifi-
cantly. Visit your Toyota dealer immediately with all remaining electronic
keys that were provided with your vehicle.
