Opening, closing and locking the doors

■When electronic key function stops

If the position of the electronic key has not changed for a certain amount of time such as when the electronic key is left some where, the function of the electronic key stops to reduce depletion of the battery.

■Conditions affecting operation

The smart key system uses weak radio waves. In the following situations, the communication between the electronic key and the vehicle may be affected, preventing the smart key system, wireless remote control and engine immobilizer system from operating properly.

  • 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 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
    • Metallic wallets or bags
    • Coins
    • Hand warmers made of metal
    • Media such as CDs and DVDs
  • 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 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
  • When the electronic key is placed near a battery charger or electronic devices
  • When the vehicle is parked in a pay parking spot where radio waves are emitted

If the doors cannot be locked/unlocked using the smart key system, lock/unlock the doors by performing any of the following:

  • Bring the electronic key close to either front door handle and operate the entry function.
  • Operate the wireless remote control.

If the doors cannot be locked/unlocked using the above methods, use the mechanical key.

If the engine cannot be started using the smart key system.

■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 compartment or floor, or in the door pockets or glove box when the engine is started or engine 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 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 electronic 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.
  • The doors may unlock or lock 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 seconds 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.)
  • If the doors have been locked from outside of the vehicle and are then not unlocked using the wireless remote control or smart key system, the engine cannot be started using the smart key system.

    (However, if the doors have been locked from inside the vehicle, the engine can be started using the smart key system.) If it is necessary to start the engine, it can be started using the procedure in "If the electronic key dose not operate properly".

  • Touching the door lock or unlock sensor while wearing gloves may prevent lock or unlock operation.
  • When the lock operation is performed using the lock sensor, recognition 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 lock and unlock repeatedly. In that case, follow the following correction procedures to wash the vehicle:
    • Place the electronic key in a location 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.
  • 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 vehicle.

    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 handle operation or a handle operation immediately after entering the effective range may prevent the doors from being unlocked. Touch the door unlock sensor and check that the doors are unlocked 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.
  • Fingernails may scrape against the door during operation of the door handle. Be careful not to injure fingernails or damage the surface of the door.

■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.
  • Setting the electronic key to battery- saving mode helps to reduce key battery depletion.

■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 key system does not operate properly

  • Locking and unlocking the doors
  • Starting the engine

■Customization

Some functions can be customized.

■If the smart key system has been deactivated in a customized setting

  • Locking and unlocking the doors: Use the wireless remote control or mechanical key.
  • Starting the engine and changing engine switch modes.
  • Stopping the engine.

WARNING

■Caution regarding interference with electronic devices

  • People with implantable cardiac pacemakers, cardiac resynchronization therapy- pacemakers or implantable cardioverter defibrillators should keep away from the smart key system antennas. The radio waves may affect the operation of such devices. If necessary, the entry function can be disabled. Ask your Toyota dealer for details, such as the frequency of radio waves and timing of the emitted radio waves. Then, consult your doctor to see if you should disable the entry function.
  • Users of any electrical medical device other than implantable cardiac pacemakers, cardiac resynchronization therapy- pacemakers or implantable cardioverter defibrillators should consult the manufacturer of the device for information about its operation under the influence of radio waves.

    Radio waves could have unexpected effects on the operation of such medical devices.

Ask your Toyota dealer for details on disabling the entry function.
