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.
