Before driving
Using the mechanical key
Take out the mechanical key.
The mechanical key can only be
inserted in one direction, as the key
only has grooves on one side. If the
key cannot 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 mechanical 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. 4 1 7 )
nCard key
lThe mechanical key that is stored inside the card key should be used only if a
problem arises, such as when the key does not operate properly.
lIf 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.

nWhen required to leave a key to the vehicle with a parking attendant
Turn the trunk opener main switch off and lock the glove box as circumstances
demand. (→P. 4 3 , 2 5 1 )
Remove the mechanical key for your own use and provide the attendant with the
electronic key only.
nKey number plate
Keep the plate in a safe place such as your wallet, not in the vehicle. In the event that
a mechanical key is lost, a new key can be made at your Lexus dealer using the key
number plate. (→P. 4 1 6 )
NOTICE
nTo prevent key damage
Observe the following.
lDo not drop the keys, subject them to strong shocks or bend them.

lDo not get the keys wet or wash them in an ultrasonic washer etc.
lDo not attach metallic or magnetic materials to the keys or place the keys close to
such materials.
lDo not disassemble the electronic keys.
lDo not place the keys near objects that produce magnetic fields, such as TVs,
audio systems, glass top ranges, or medical electrical equipment, such as low-fre-
quency therapy equipment.

the battery falls out or if the battery was
removed because the key got wet, rein-
stall the battery with the positive termi-
nal facing the Lexus emblem.

NOTICE
nPrecautions for handling the card keys
lDo not apply excess force when inserting the mechanical key to the card key.
Doing so may damage the card key.
lIf 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,
immediately 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.
lDo 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.
lIf the battery cover is frequently removed, the battery cover may become loose.
lWhen 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 rap-
idly.
lThe surface of the card key may be damaged, or its coating may peel off in the
following situations.

28
1-2. Opening, closing and locking the doors and trunk
nOperation signals
A buzzer sounds and the emergency flashers flash to indicate that the doors have
been locked/unlocked. (Locked: Once; Unlocked: Twice)
nConditions affecting operation
The smart access system with push-button start uses weak radio waves. In the fol-
lowing situations, the communication between the electronic key and the vehicle
may be affected, preventing the smart access system with push-button start from
operating properly:
(Ways of coping: →P. 4 1 7 )
lWhen the electronic key battery is depleted
lNear a TV tower, electric power plant, gas station, radio station, large display,
airport or other facility that generates strong radio waves or electrical noise
lWhen carrying a portable radio, cellular phone, cordless phone or other wire-
less communication devices
lWhen the electronic key is in contact with, or is covered by the following metal-
lic objects

1-2. Opening, closing and locking the doors and trunk
nBattery-saving function
In the following circumstances, the entry function is disabled in order to prevent the
vehicle and electronic key batteries from discharging.
lWhen the entry function has not been used for a month or more
lWhen the electronic key has been left within approximately 3 ft. (1 m) of the
vehicle for 10 minutes or more
The system will resume operation when
lThe vehicle is locked using the door handle lock switch.
lThe vehicle is locked/unlocked using the wireless remote control function.
(→P. 36 )
lThe vehicle is locked/unlocked using the mechanical key. (→P. 41 7 )
nElectronic key battery depletion
lThe standard battery life is 1 to 2 years. (The card key battery life is about a year
and a half.)
lThe battery becomes depleted even if the electronic key is not used because
the key always transmits radio waves. If the smart access system with push-but-
ton start or the wireless remote control does not operate, or the detection area
becomes smaller, the battery may be depleted. Replace the battery when nec-
essary.
(→ P. 345)

the following electrical appliances that produce a magnetic field.
