Even when the electronic key is

within the effective range (detec-

tion areas), the system may not

operate properly in the following

cases:

• The electronic key is too close to

the window or outside door han-

dle, near the ground, or in a high

place when the doors are locked

or unlocked.

• The electronic key is on the instru-

ment panel, luggage cover or

floor, or in the door pockets or

glove box when the EV system is

started or power switch modes 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

wave reception conditions, it may

be detected by the antenna out-

side 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, the

doors may be locked or unlocked

by anyone. However, only the

doors detecting the electronic key

can be used to lock or unlock the

vehicle.

●

Even if the electronic key is not

inside the vehicle, it may be possi-

ble to start the EV system if the

electronic key is near the window.

●

The doors may unlock if a large

amount of water splashes 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

locked after approximately 60 sec-

onds if the doors are not opened

and closed.)

●

If the wireless remote control is

used to lock the doors when the

electronic key is near the vehicle,

there is a possibility that the door

may not be unlocked by the entry

function. (Use the wireless remote

control to unlock the doors.)

●

Touching the door lock sensor

while wearing gloves may delay or

prevent lock operation. Remove

the gloves and touch the lock sen-

sor again.

●

When the lock operation is per-

formed using the lock sensor, rec-

ognition signals 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 within

the effective range, the door may

190

4-2. Opening, closing and locking the doors

lock and unlock repeatedly. In that

case, follow the following correc-

tion procedures to wash the vehi-

cle:

• Place the electronic key in a loca-

tion 6 ft. (2 m) or more away from

the vehicle. (Take care to ensure

that the key is not stolen.)

• Set the electronic key to battery-

saving mode to disable the smart

key system. (

P.188)

●

If the electronic key is inside the

vehicle and a door handle

becomes wet during a car wash, a

message may be shown on the

multi-information display and a

buzzer will sound outside the vehi-

cle. To turn off the alarm, lock all

the doors.

●

The lock sensor may not work

properly if it comes into contact

with ice, snow, mud, etc. Clean

the lock sensor and attempt to

operate it again.

●

A sudden approach to the effec-

tive range or door handle may pre-

vent the doors from being

unlocked. In this case, return the

door handle to the original position

and check that the doors unlock

before pulling the door handle

again.

●

If there is another electronic key in

the detection area, it may take

slightly longer to unlock the doors

after the door handle is gripped.

■

When the vehicle is not driven

for extended periods

●

To prevent theft of the vehicle, do

not leave the electronic key within

6 ft. (2 m) of the vehicle.

●

The smart key system can be

deactivated in advance. (



P.569)

●

Battery-saving mode can reduce

the power consumption of elec-

tronic keys. (

■

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

system from the outside of the vehi-

cle.
Depending on the position and hold-

ing condition of the electronic key,

the key may not be detected cor-

rectly and the system may not oper-

ate properly. (The alarm may go off

accidentally, or the door lock pre-

vention may not operate.)

■

If the smart key system does

not operate properly

●

If the doors cannot be locked or

unlocked, perform the following.

• Bring the electronic key close to

the door handle and perform a

lock or unlock operation.

• Use the wireless remote control.
If the doors cannot be locked or
unlocked by perform the above, use
the mechanical key. (



P.539)

However, if the mechanical key is
used while the alarm system is set,
the warning will sound. (

P.69)

●

If the EV system cannot be

started, refer to P.540

WARNING

■

Caution regarding interfer-

ence with electronic devices

●

People with implantable car-

diac pacemakers, cardiac

resynchronization therapy-

pacemakers or implantable car-

dioverter defibrillators should

keep away from the smart key

system antennas. (



P.187)

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.

●

User of any electrical medical

device other than implantable

cardiac pacemakers, cardiac

resynchronization therapy-

pacemakers or implantable car-

dioverter 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

for disabling the entry function.
