INFINITI INTELLIGENT KEY
Your vehicle can only be driven with the Intel-
ligent Keys which are registered to your vehi-
cle’s Intelligent Key System components and
INFINITI Vehicle Immobilizer System
components.Never leave the keys in the vehicle.
As many as four Intelligent Keys can be reg-
istered and used with one vehicle. The new
keys must be registered prior to use with the
Intelligent Key System and INFINITI Vehicle
Immobilizer System of your vehicle. It is rec-
ommended that you visit an INFINITI retailer
for this service. Since the registration process
requires erasing all memory in the Intelligent
Key components when registering new keys,
be sure to take all Intelligent Keys that you
have to an INFINITI retailer.A key number plate is supplied with your keys.
Record the key number and keep it in a safe
place (such as your wallet), not in the vehicle.
If you lose your keys, it is recommended that
you visit an INFINITI retailer for duplicates by
using the key number. INFINITI does not re-
cord key numbers so it is very important to
keep track of your key number plate.
A key number is only necessary when you
have lost all keys and do not have one to
duplicate from. If you still have a key, it can be
duplicated without knowing the key number.
CAUTION
Be sure to carry the Intelligent Key with
you when driving. The Intelligent Key is a
precision device with a built-in transmit-
ter. To avoid damaging it, please note the
following:
– The Intelligent Key is water resistant;
however, wetting may damage the In-
telligent Key. If the Intelligent Key gets
wet, immediately wipe until it is com-
pletely dry.
– Do not bend, drop or strike it against
another object.
– If the outside temperature is below 14°F
(-10°C), the battery of the Intelligent
Key may not function properly.LPD2848

–Do not place the Intelligent Key for an
extended period in a place where tem-
peratures exceed 140°F (60°C).
– Do not change or modify the Intelligent
Key.
– Do not use a magnet key holder.
– Do not place the Intelligent Key near an
electric appliance such as a television set
or a personal computer.
– Do not allow the Intelligent Key to come
into contact with water or salt water,
and do not wash it in a washing machine.
This could affect the system function.
If an Intelligent Key is lost or stolen, INFINITI
recommends erasing the ID code of that In-
telligent Key from the vehicle. This may pre-
vent the unauthorized use of the Intelligent
Key to operate the vehicle. For information
regarding the erasing procedure, it is recom-
mended that you visit an INFINITI retailer.
Mechanical key
The Intelligent Key contains the mechanical
key.
To remove the mechanical key, release the
lock knob on the back of the Intelligent Key.
To install the mechanical key, firmly insert it
into the Intelligent Key until the lock knob
returns to the lock position.
Use the mechanical key to lock or unlock the
driver's door and glove box if they are
equipped with a key cylinder.
CAUTION
Always carry the mechanical key installed
in the Intelligent Key slot.
For additional information, see “Doors”
(P. 3-4) and “Storage” (P. 2-50).
Valet hand-off
When you have to leave a key with a valet,
give them the Intelligent Key itself and keep
the mechanical key with you to protect your
belongings.
To prevent the glove box from being opened
during valet hand-off, follow the procedure
below.
1. Remove the mechanical key from the In- telligent Key.
2. Lock the glove box with the mechanical key.
3. Hand the Intelligent Key to the valet and keep the mechanical key with you.
For additional information, see “Storage”
(P. 2-50).

INFINITI VEHICLE IMMOBILIZER
SYSTEM KEYS
Additional or replacement keys:
If you still have a key, the key number is not
necessary when you need extra INFINITI Ve-
hicle Immobilizer System keys. Your existing
key can be duplicated without knowing the
key number. As many as four INFINITI Ve-
hicle Immobilizer System keys can be used
with one vehicle. You should bring all
INFINITI Vehicle Immobilizer System keys
that you have to the INFINITI retailer for
registration. This is because the registration
process will erase the memory of all key
codes previously registered into the INFINITI
Vehicle Immobilizer System. After the regis-
tration process, these components will only
recognize keys coded into the INFINITI Ve-
hicle Immobilizer System during registration.
Any key that is not given to the retailer at the
time of registration will no longer be able to
start your vehicle.
CAUTION
Do not allow the immobilizer system key,
which contains an electrical transponder,
to come into contact with water or salt
water. This could affect system function. When the doors are locked using one of the
following methods, the doors cannot be
opened using the inside or outside door
handles. The doors must be unlocked to open
the doors.
WARNING
• Always have the doors locked while driv-
ing. Along with the use of seat belts, this
provides greater safety in the event of an
accident by helping to prevent persons
from being thrown from the vehicle. This
also helps keep children and others from
unintentionally opening the doors, and
will help keep out intruders.
• Before opening any door, always look for
and avoid oncoming traffic.
• To help avoid risk of injury or death
through unintended operation of the ve-
hicle and/or its systems, including en-
trapment in windows or inadvertent
door lock activation, do not leave chil-
dren, people who require the assistance
of others or pets unattended in your ve-
hicle. Additionally, the temperature in-
side a closed vehicle on a warm day can
quickly become high enough to cause a
significant risk of injury or death to
people and pets.

Lockout protection
When any door is open and the power door
lock switch is moved to the lock position, all
doors will lock. If the Intelligent Key is left in
the vehicle after the door is closed, all doors
will unlock automatically and a chime will
sound.
These functions help to prevent the Intelli-
gent Key from being accidentally locked in-
side the vehicle.
AUTOMATIC DOOR LOCKS
• All doors lock automatically when the ve-hicle speed reaches 15 mph (24 km/h).
• All doors unlock automatically when the transmission is placed in the P (Park) posi-
tion or when the ignition switch is placed in
the OFF position depending on the option
selected in the “Comfort & Convenience”
options of the “Settings” menu.
NOTE:The Auto unlock features can be changed
using “Comfort & Convenience” options in
the “Settings” menu of the lower touch-
screen display. For additional information,
refer to the separate INFINITI InTouch™
Owner’s Manual.
CHILD SAFETY REAR DOOR
LOCK
Child safety locks help prevent the rear doors
from being opened accidentally, especially
when small children are in the vehicle.
The child safety lock levers are located on the
edge of the rear doors.
When the lever is in the LOCK position, the
door can be opened only from the outside.
WARNING
• Radio waves could adversely affect elec-
tric medical equipment. Those who use a
pacemaker should contact the electric
medical equipment manufacturer for the
possible influences before use.
• The Intelligent Key transmits radio
waves when the buttons are pressed.
The FAA advises the radio waves may
affect aircraft navigation and communi-
cation systems. Do not operate the Intel-
ligent Key while on an airplane. Make
sure the buttons are not operated unin-
tentionally when the unit is stored for a
flight.
• Before leaving the vehicle, engage the P
(Park) position and check that the elec-
tronic parking brake warning light is illu-
minated to confirm that the electronic
parking brake is applied. The electronic
parking brake warning light will remain
on for a period of time after the driver’s
door is locked.

INFINITI INTELLIGENT KEY SYSTEM
3-6Pre-driving checks and adjustments

•Make sure to engage the P (Park) posi-
tion and apply the parking brake when
parking your vehicle, riding on or off the
vehicle or loading luggage. Failure to do
so could cause the vehicle to move or roll
away unexpectedly and result in serious
personal injury or property damage.
The Intelligent Key system can operate all the
door locks using the remote control function
or pushing the request switch on the vehicle
without taking the key out from a pocket or
purse. The operating environment and/or
conditions may affect the Intelligent Key sys-
tem operation.
Be sure to read the following before using the
Intelligent Key system.
CAUTION
• Be sure to carry the Intelligent Key with
you when operating the vehicle.
• Never leave the Intelligent Key in the ve-
hicle when you leave the vehicle. The Intelligent Key is always communicating
with the vehicle as it receives radio waves.
The Intelligent Key system transmits weak
radio waves. Environmental conditions may
interfere with the operation of the Intelligent
Key system under the following operating
conditions:
• When operating near a location where
strong radio waves are transmitted, such as
a TV tower, power station and broadcast-
ing station.
• When in possession of wireless equipment, such as a cellular telephone, transceiver or
a CB radio.
• When the Intelligent Key is in contact with or covered by metallic materials.
• When any type of radio wave remote con- trol is used nearby.
• When the Intelligent Key is placed near an electric appliance such as a personal
computer.
• When the vehicle is parked near a parking meter.
In such cases, correct the operating condi-
tions before using the Intelligent Key function
or use the mechanical key. Although the life of the battery varies de-
pending on the operating conditions, the bat-
tery’s life is approximately two years. If the
battery is discharged, replace it with a new
one.
When the Intelligent Key battery is low, a
“Key Battery Low” indicator illuminates in the
vehicle information display. For additional in-
formation, see “Vehicle information display
warnings and indicators” (P. 2-21).
Since the Intelligent Key is continuously re-
ceiving radio waves, if the key is left near
equipment which transmits strong radio
waves, such as signals from a TV and per-
sonal computer, the battery life may become
shorter.
For additional information, see “Battery re-
placement” (P. 8-22).
CAUTION
Listed below are conditions or occurrences
which will damage the Intelligent Key:
• Do not allow the Intelligent Key, which
contains electrical components, to come
into contact with water or salt water.
This could affect the system function.
• Do not drop the Intelligent Key.
Pre-driving checks and adjustments3-7

•Do not strike the Intelligent Key sharply
against another object.
• Do not change or modify the Intelligent
Key.
• Wetting may damage the Intelligent
Key. If the Intelligent Key gets wet, im-
mediately wipe until it is completely dry.
• Do not place the Intelligent Key for an
extended period in an area where tem-
peratures exceed 140°F (60°C).
• Do not attach the Intelligent Key with a
key holder that contains a magnet.
• Do not place the Intelligent Key near
equipment that produces a magnetic
field, such as a TV, audio equipment and
personal computers.
If an Intelligent Key is lost or stolen, INFINITI
recommends erasing the ID code of that In-
telligent Key from the vehicle. This may pre-
vent the unauthorized use of the Intelligent
Key to operate the vehicle. For information
regarding the erasing procedure, it is recom-
mended that you visit an INFINITI retailer.
OPERATING RANGE
The Intelligent Key functions can only be used
when the Intelligent Key is within the speci-
fied operating range from the door handle
request switch or the one touch unlock sen-
sor
O1. When the Intelligent Key battery is dis-
charged or strong radio waves are present
near the operating location, the Intelligent
Key operating range becomes narrower, and
the Intelligent Key may not function properly.
The operating range is within 31.5 in (80 cm)
from each request switch or one touch unlock
sensor
O1.
If the Intelligent Key is too close to the door
glass, handle or rear bumper, the request
switches or the one touch unlock sensor may
not function.
If any of the front doors are recently closed
and locked, you must wait 2 seconds before
you can unlock the door with the one touch
unlock sensor. Pulling the handle within 2
seconds of locking the door will allow you
time to confirm that the door has been locked
without accidentally unlocking the door with
the one touch unlock sensor.
If you pull the door handle with your gloved
hand, the one touch unlock sensor operation
may not function.
When the Intelligent Key is within the operat-
ing range, it is possible for anyone, even
someone who does not carry the Intelligent
Key, to push the request switch or the one
touch unlock sensor to lock/unlock the door
within range.
