NISSAN INTELLIGENT KEY® (if so
equipped)
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

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.
CAUTION
Listed below are conditions or occur-
rences which will damage the Intelli-
gent Key:
• Do not allow the Intelligent Key,
which contains electrical compo-
nents, to come into contact with wa-
ter or salt water. This could affect the
system function.
• Do not drop the Intelligent Key.
• Do not strike the Intelligent Key
sharply against another object.
• Do not change or modif y the Intelli-
gent Key.
• Wetting may damage the Intelligent
Key. If the Intelligent Key gets wet,
immediately wipe until it is com-
pletely dry.
• Do not place the Intelligent Key for an
extended period in an area where
temperatures exceed 140°F (60°C).
• Do not attach the Intelligent Key with
a key holder that contains a magnet.
