■ Effective range (areas within which the electronic key is detected)
When starting the engine or changing engine switch modes
The system can be operated when the electronic key is inside the vehicle.
(The electronic key is not detected when it is on the floor or on the instru-
ment panel.)
■ Battery-saving function
The battery-saving function will be activated in order to prevent the electronic
key battery and the battery from being discharged while the vehicle is not in
operation for a long time.
■ Electronic Key Battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping
the electronic key from receiving radio waves.
When locking or unlocking the doors

■ Conditions affecting operation
The smart entry & start 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 entry & start system, wireless remote control
and engine immobilizer system from operating properly.
(Ways of coping: P. 668)
● When the electronic key battery is depleted
● Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility 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 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 pers onal digital assistants (PDAs)
• Digital audio players
• Portable game systems
● If window tint with a metallic content or metallic objects are attached to the
rear window
● When the electronic key is placed near a battery charger or electronic devices

2023-2. Opening, closing and locking the doors
HILUX_OM_OM0K321E_(EE)
■ Note for the entry function
● Even if the electronic key is within the effective range (detection areas)
when locking or unlocking the doors, the system may not operate properly if
the electronic key is too close to the window or outside door handle, near
the ground, or in a high place.
● 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 recep-
tion conditions, it may be detected by the antenna outside the cabin and the
doors 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 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.
● 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.)
● Pulling the outside door handle while pressing the lock/unlock button on the
outside door handle may prevent the doors from being unlocked. In this
case, return the door handle to the original position, press the lock/unlock
button again, and check that the doors unlock before pulling the door handle
again.
● Unlocking the vehicle may take more time if another electronic key is within
the effective range.
■ When the vehicle is not driven for extended periods
● To prevent theft of the vehicle, do not leave the electronic key within 2 m
(6 ft.) of the vehicle.
● The smart entry & start system can be deactivated in advance. Ask any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer for details.
■ 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 vehicle.
Depending on the position and holding condition of the electronic key, the key
may not be detected correctly and the system may not operate properly. (The
alarm may go off accidentally, or the door lock prevention function may not
operate.)

■ If the smart entry & start system does not operate properly
● Locking and unlocking the doors: Use the mechanical key. (P. 668)
● Starting the engine: P. 669
■ 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 when the engine
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. 599)
• The smart entry & start 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.
● To avoid serious deterioration, do not leave the electronic key within 1 m (3
ft.) of the following electrical 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 “KEY LEFT INSIDE VEHICLE”/“Key left inside vehicle” is shown on the
multi-information display (if equipped)
An attempt was made to lock the doors using the smart entry & start system
while the electronic key was still inside the vehicle, or an attempt was made
to lock either front door by opening a door and putting the inside lock button
into the lock position, then closing the door by pulling on the outside door
handle with the electronic key still inside the vehicle.
Retrieve the electronic key from the vehicle and lock the doors again.
