NISSAN VEHICLE IMMOBILIZER
SYSTEM KEYS
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 not
given to the dealer at the time of registra-
tion will no longer be able to start your
vehicle.
CAUTION
Do not allow the immobilizer system
key, which contains an electrical tran-
sponder, to come into contact with wa-
ter or salt water. This could affect sys-
tem 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
driving. 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 uninten-
tionally opening the doors, and will
help keep out intruders.
• Before opening any door, always look
for and avoid oncoming traffic.
DOORS
3-4Pre-driving checks and adjustments

WARNING
• Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
• The Intelligent Key transmits radio
waves when the buttons are pressed.
The FAA advises the radio waves may
affect aircraf t navigation and com-
munication systems. Do not operate
the Intelligent Key while on an air-
plane. Make sure the buttons are not
operated unintentionally when the
unit is stored for a flight.
• Never leave the Intelligent Key in the
vehicle when you leave the vehicle.
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 environ-
ment and/or conditions may affect the In-
telligent Key system 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.
The Intelligent Key is capable of receiving
and transmitting radio waves. The Intelli-
gent Key system transmits weak radio
waves from various distances. Environ-
mental conditions may interfere with the
operation of the Intelligent Key system un-
der the following operating conditions:
• When operating near a location where strong radio waves are transmitted, such
as a TV tower, power station and broad-
casting station.
• When in possession of wireless equip- ment, such as a cellular telephone, trans-
ceiver, 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 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, a
yellow indicator illuminates with the mes-
sage “Key Battery Low” in the vehicle infor-
mation display. For additional information,
see “Vehicle information display warnings
and indicators” (P. 2-26).
Since the Intelligent Key is capable of 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, see “Battery re-
placement” (P. 8-21).
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.

The light blinks only when you press any
button on the Intelligent Key. The light illu-
mination only signifies that the key fob has
transmitted a signal. You may look and/or
listen to verif y that the vehicle has per-
formed the intended operation. The num-
ber of blinks identifies each registered key
(i.e. 1 blink = 1st key,...,4 blinks = 4th key) for
your own identification purposes. If the light does not blink, your battery may
be too weak to communicate to the ve-
hicle. If this occurs, the battery may need to
be replaced. For additional information re-
garding the replacement of a battery, see
“Battery replacement” (P. 8-21).
