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. 550)
■Panic mode
■Card key
●The mechanical key that is stored inside the card key should be used only in an emer-
gency, such as when the key does not operate properly.
●If it is difficult to take out the mechanical key, push down the lock release button using a
pen tip etc. If it is difficult to pull it out, use a coin etc.
Using the mechanical key
When is pressed for longer than about
one second, an alarm will sound intermittently
and the vehicle lights will flash to deter any per-
son from trying to break into or damage your
vehicle.
To stop the alarm, press any button on the elec-
tronic key.
●To store the mechanical key in the card key,

LX570_OM_OM60T33U_(U)3-1. Key information
●The card key is not waterproof.
■When required to leave the vehicle’s key with a parking attendant
Lock the glove box as circumstances demand. (
P. 429)
Remove the mechanical key for your own use and provide the attendant with the elec-
tronic key only.
■If you lose your mechanical keys
New genuine mechanical keys can be made by your Lexus dealer using another
mechanical key and the key number stamped on your key number plate. Keep the plate
in a safe place such as your wallet, not in the vehicle.
■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. (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.
●As the electronic key always receives ra dio waves, the battery will become depleted
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. 507)
• 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
●If the battery cover is not installed and the bat-
tery falls out or if the battery was removed
because the key got wet, reinstall the battery
with the positive terminal facing the Lexus
emblem.

NOTICE
■Handling the card keys
●Do not apply excess force when inserting the mechanical key to the card key.
Doing so may damage the card key.
●If the battery or card key terminals get wet, the battery may corrode and the card key
may stop working.
If the key is dropped into water, or if drin
king water etc. is spilled on the key, immedi-
ately remove the battery cover and wipe the battery and terminals.
(To remove the battery cover, lightly grasp it and pull.) If the battery is corroded, have
your Lexus dealer replace the battery.
●Do not crush the battery cover or use a screwdriver to remove the battery cover.
Forcibly removing the battery cover may bend or damage the key.
●If the battery cover is frequently removed, the cover may become loose.
●When installing the battery, make sure to check the direction of the battery.
Installing the battery in the wrong directio n may cause the battery to deplete rapidly.
●The surface of the card key may be damaged, or its coating may peel off in the follow-
ing situations:
• The card key is carried together with hard objects, such as coins or keys.
• The card key is scraped with a sharp object, such as a tip of mechanical pencil.
• The surface of the card key is wiped with thinners or benzene.
■Carrying the electronic key on your person
Carry the electronic key 3.9 in. (10 cm) or mo re away from electric appliances that are
turned on. Radio waves emitted from electric appliances within 3.9 in. (10 cm) of the
electronic key may interfere with the key, causing the key to not function properly.
■In case of a smart access system with push-button start malfunction or other key-
related problems
Take your vehicle with all the electronic keys provided with your vehicle, including the
card key, to your Lexus dealer.
■When an electronic key is lost
If the electronic key remains lost, the risk of vehicle th eft increases significantly. Visit
your Lexus dealer immediately with all rema ining electronic keys and the card key that
