1-2. Opening, closing and locking the doors
RX350/270_EE
■Security feature
If a door is not opened within approximately 30 seconds after the vehicle is
unlocked, the security feature automatically locks the vehicle again.
■Battery-saving function
If the vehicle is parked for a long period of time, the battery-saving function is acti-
vated in order to prevent the vehicle battery from being discharged and the elec-
tronic key battery from being depleted.
●In the following circumstances, unlocking the vehicle using the entry function
may take longer than usual:
• When the entry function has not been used for 5 days or more
• When the electronic key has been left within approximately 2 m (6 ft.) of the
vehicle for 10 minutes or more
●If the entry function has not been used for 14 days or more, the vehicle cannot
be unlocked by a door other than the driver's door. To unlock the vehicle, grip
the driver's door handle or use the wireless remote control or the mechanical
key.
The system will resume operation when:
●The vehicle is locked using the lock sensor.
●The vehicle is locked/unlocked using the wireless remote control function.
(→P. 5 3 )
●The vehicle is locked/unlocked using the mechanical key. (→P. 5 9 1 )

■Conditions affecting operation
The smart entry & start system uses weak radio waves. In the following situations,
the communication between the electronic key and the vehicle may be affected,
preventing the smart entry & start system, wireless remote control and immobilizer
system from operating properly.
(Ways of coping: →P. 5 9 1 )
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas station, radio station, large display,
airport or other facility that generates strong radio waves or electrical noise
●When carrying a portable radio, cellular phone, cordless phone or other wire-
less communication device
●When the electronic key is in contact with, or is covered by the following metal-
lic 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 another wireless key (that emits radio waves) is 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 rear
window

1-2. Opening, closing and locking the doors
RX350/270_EE
■Note for the entry function
●Even when the electronic key is within the effective range (detection 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 unlocked.
• The electronic key is on the instrument panel, luggage cover or floor or in the
glove box.
●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 con-
ditions, 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, 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.
●The doors may lock or unlock if the electronic key is within the effective range
and a large amount of water splashes on the door handle, such as in the rain or
in a car wash. The doors will automatically be locked after approximately 30
seconds if a door is 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.)

■If the smart entry & start system does not operate properly
●Locking and unlocking the doors: Use the mechanical key. (→P. 5 9 1 )
●Starting the engine: →P. 5 9 2
■Electronic key battery depletion
●The standard battery life is 1 to 2 years. (The card key battery life is about a year
and a half.)
●If the battery becomes low, an alarm will sound in the cabin when the engine
stops. (→P. 5 6 3 )
●As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms indicate
that the electronic key battery may be depleted. Replace the battery when nec-
essary. (→P. 5 0 1 )
• The smart entry & start system or the wireless 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 magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Induction cookers
• Table lamps
■When the electronic key battery is fully depleted
→P. 5 0 1
■Customization
Settings (e.g. smart entry & start system) can be changed.
(Customizable features →P. 6 2 2 )
