NISSAN INTELLIGENT KEY®
Your vehicle can only be driven with the
Intelligent Keys which are registered to
your vehicle’s Intelligent Key system com-
ponents and NISSAN Vehicle Immobilizer
System components.Never leave these keys in the vehicle.
As many as four Intelligent Keys can be
registered and used with one vehicle. The
new keys must be registered prior to use
with the Intelligent Key system and NISSAN
Vehicle Immobilizer System of your vehicle.
It is recommended that you visit a NISSAN
dealer for this service. Since the registra-
tion process requires erasing all memory in
the Intelligent Key components when reg-
istering new keys, be sure to take all Intelli-
gent Keys that you have to the NISSAN
dealer.
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 recom-
mended that you visit a NISSAN dealer for
duplicates by using the key number.
NISSAN does not record 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.

If an Intelligent Key is lost or stolen, NISSAN
recommends erasing the ID code of that
Intelligent Key from the vehicle. This may
prevent the unauthorized use of the Intelli-
gent Key to operate the vehicle. For infor-
mation regarding the erasing procedure, it
is recommended that you visit a NISSAN
dealer.
Mechanical key

cal 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 doors and glove box.
For additional information, refer to “Doors”
in this section and “Storage” in the “Instru-
ments and controls” section of this manual.

NISSAN VEHICLE IMMOBILIZER
SYSTEM KEYS
You can only drive your vehicle using the
Intelligent Keys which are registered to the
NISSAN Vehicle Immobilizer System com-
ponents in your vehicle.
The mechanical key can be used for all the
locks.
Never leave the keys in the vehicle.
Additional or replacement keys:
If you still have a key, the key number is not
necessary when you need extra NISSAN
Vehicle Immobilizer System keys. Your ex-
isting key can be duplicated without know-
ing the key number. As many as four
NISSAN Vehicle Immobilizer System keys
can be used with one vehicle. You should
bring all NISSAN Vehicle Immobilizer Sys-
tem keys that you have to the NISSAN
dealer for registration. This is because the
registration process will erase the memory
of all key codes previously registered into
the NISSAN Vehicle Immobilizer System. Af-
ter the registration process, these compo-
nents will only recognize keys coded into
the NISSAN Vehicle Immobilizer System
during registration. Any key that is notgiven to the dealer at the time of registra-
tion will no longer be able to start your
vehicle.

∙ To help avoid risk of injury or deaththrough unintended operation of the
vehicle and/or its systems, including
entrapment in windows and/or inad-
vertent door lock activation, do not
leave children, people who require the
assistance of others and/or pets un-
attended in your vehicle. Additionally,
the temperature inside a closed ve-
hicle on a warm day can quickly be-
come high enough to cause a signifi-
cant risk of injury or death to people
and pets.

In such cases, correct the operating condi-
tions before using the Intelligent Key func-
tion or use the mechanical key.
Although the life of the battery varies de-
pending on the operating conditions, the
battery’s life is approximately two years. If
the battery is discharged, replace it with a
new one.
When the Intelligent Key battery is low, an
indicator illuminates in the vehicle informa-
tion display. For additional information, re-
fer to “Vehicle information display” in the
“Instruments and controls” section of this
manual.
Since the Intelligent Key is continuously re-
ceiving radio waves, if the key is lef t near
equipment which transmits strong radio
waves, such as signals from a TV and per-
sonal computer, the battery life may be-
come shorter.
For additional information, refer to “Battery
replacement” in the “Do-it-yourself ” section
of this manual. As many as four Intelligent Keys can be
registered and used with one vehicle. For
information about the purchase and use of
additional Intelligent Keys, it is recom-
mended that you visit a NISSAN dealer.
