SERVICE INFORMATION
When replacing or adding an Intelligent Key, it is very important to make sure the correct Intelligent Key is
selected from the parts department.

A running change was made that will help identify the correct Intelligent Key.

Beginning in late 2017 and early 2018 the last five digits of the Intelligent Key part number is marked
on the Intelligent Key under the mechanical key.
 See page 2 for location images of this part number addition.
NOTE:

A correct Intelligent Key may or may not have the last five digits of the part number as shown on
page 2.

The above running change was applied as a “help” to identify the correct Intelligent Key for a given
vehicle, but the actual part number listed in the parts catalog did not change.

Make sure to use the electronic parts catalog to confirm the correct Intelligent Key for a given vehicle.
Infiniti Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are properly trained
individuals who have the equipment, tools, safety instruction, and know-how to do a job properly and safely. NOTE: If you believe that
a described condition may apply to a particular vehicle, DO NOT assume that it does. See your Infiniti retailer to determine if this
applies to your vehicle.

Intelligent Key Registration Tips

Only an Intelligent Key that has never been initialized/registered can be initialized/registered, and to
one vehicle only.

Once an Intelligent Key has been initialized/registered to one vehicle, it cannot be initialized/registered
to another vehicle.
Examples:
 If a new Intelligent Key is “borrowed” from the parts department and is initialized/registered to a
vehicle “for testing purposes”, it cannot later be sold for use on another vehicle since it cannot be
reinitialized/reregistered again.
 An Intelligent Key cannot be “borrowed” from a known good vehicle for testing purposes.

Two (2) quick tones will be heard when an Intelligent Key has been successfully initialized/registered
via the ignition switch.

More than two tones are heard when an Intelligent Key has not been initialized/registered via the
ignition switch.

The two most common reasons why an Intelligent Key will not initialize (more than two tones heard)
are:
 The Intelligent Key is registered to another vehicle.
 The wrong Intelligent Key (one that is incorrect for the vehicle application) is being used.
