Operation of each component
IS300h_EE(OM53C61E)
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. 544)

■Card key (if equipped)
●The card key is not waterproof.
●The mechanical key that is stored inside the card key should be used only if a problem
arises, such as when the card 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 still difficult to pull it out, use a coin etc.
■When required to leave the vehicle’s key with a parking attendant
Set the luggage security system (→P. 145) on and lock the glove box (→P. 414) as cir-
cumstances demand.
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 any authorized Lexus dealer or repairer,
or another duly qualified and equipped professional using the other 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.

tery falls out or if the battery was removed
because the key got wet, reinstall the battery

■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 hybrid system is
stopped. (→P. 5 2 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 elec-
tronic key battery may be depleted. Replace the battery when necessary. (→P. 4 7 1 )
• The smart entry & start system 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 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
• Table lamps
• Induction cookers
■Replacing the battery
→P. 4 7 1
■Confirmation of the registered key number
The number of keys already registered to the vehicle can be confirmed. Ask any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped professional for
details.
■If a wrong key is used
The key cylinder rotates freely to isolate inside mechanism.

If the electronic key remains lost, the risk of vehicle theft increases significantly. Visit
any authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional immediately with all remaining electronic keys and the card key that were
provided with your vehicle.
■Handling the card key
●Do not apply excess force when inserting the mechanical key into the card key. Doing
so may damage the card key.
●If the battery or card key terminals get wet, the battery may corrode.
If the key is dropped into water, or if drinking 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 and pull it.) If the battery is corroded, have any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional 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 battery cover may become loose.
●When installing the battery, make sure to check the direction of the battery.
Installing the battery in the wrong direction 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 and keys.
• The card key is scraped with a sharp object, such as the tip of a mechanical pencil.
• The surface of the card key is wiped with thinner or benzene.
