If you lose your keys
New genuine keys can be made by your Toyota dealer using the ot her key

smart key system) and the key number stamped on your key number plate.

When bringing a key with wireless remote control function onto an aircraft,
make sure you do not press any buttons on the key while inside the aircraft
cabin. If you are carrying the key in your bag etc., ensure tha t the buttons are
not likely to be pressed accidentally. Pressing a button may cause the key to
emit radio waves that could interfere with the operation of the aircraft.

ing situations:
● When the wireless key battery is depleted
● Near a TV tower, electric power plant, gas station, radio stati on, large dis-

Key battery depletion
Vehicles with a smart key system
● The standard battery life is 1 to 2 years.
● If the battery becomes low, an alarm will sound in the cabin wh en 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. 455)
• The smart key system or the wireless remote control does not o perate.
• 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 3 ft. (1
m) of the following electrical appliances that produce a magnet ic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Table lamps
• Induction cookers
Vehicles without a smart key system
If the wireless remote control function does not operate, the b attery may be
depleted. Replace the battery when necessary. ( P. 455)
■ Precautions when disconnecting the battery (vehicles with a sma rt key
system)
● In some cases, it may not be possible to unlock the doors using the smart
key system immediately after the battery has been disconnected. Use the
wireless remote control or the mechanical key to lock or unlock the doors.
● The engine may not start on the first attempt after reconnectin g the battery
but will start normally after the second attempt. This is not a malfunction.
● The engine switch mode is memorized by the vehicle. When the ba ttery is
reconnected, the system will return to the mode it was in befor e the battery
was disconnected. Before disconnecting the battery, turn the en gine switch
off.
If you are unsure what mode the engine switch was in when the b attery was
disconnected, be especially careful when reconnecting the batte ry.

NOTICE
■To prevent key damage
● Do not drop the keys, subject them to strong shocks or bend them.

lems (vehicles with a smart key system)
Take your vehicle with all the electronic keys provided with your vehicle to
your Toyota dealer.
