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. (

P. 699)

■

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

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.
