Operation of each component
To take out the mechanical key, push
the release button and take the key out.
The mechanical key can only be
inserted in one direction, as the key only
has grooves on one side. If the key can-
not be inserted in a lock cylinder, turn it
over and re-attempt to insert it.
After using the mechanical key, store it
in the electronic key. Carry the mechan-
ical key together with the electronic key.
If the electronic key battery is depleted
or the entry function does not operate
properly, you will need the mechanical
key. ( P. 547)

tronic key only.

■When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not press any but-
tons on the electronic key while inside the aircraft cabin. If you are carrying an electronic
key in your bag etc., ensure
that the buttons are not likely to be pressed accidentally.
Pressing a button may cause the electronic key to emit radio waves that could interfere
with the operation of the aircraft.
■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 is stopped.

even if the electronic key is not used. The following symptoms indicate that the elec-
tronic key battery may be depleted. Replace the battery when necessary. ( P. 492)
• The smart access system with push-button start 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 3 ft. (1 m) 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
●Battery-saving mode can reduce the power consumption of electronic keys that are not
used for long periods of time. ( P. 127)

related problems
Take your vehicle with all the electronic keys provided with your vehicle to your Lexus
