SERVICE INFORMATION
If the Intelligent Key is stored within 15 feet of the vehicle, the BCM may continue to “ping” the Intelligent Key,
keeping it awake. Keeping the Intelligent Key awake may result in discharging its battery in a much shorter
period of time than normal (premature battery discharge).
Example: The Intelligent Key should not be stored in a lock box or other storage container attached to the
outside of the vehicle.
To prevent premature Intelligent Key battery discharge, store the Intelligent Key more than 15 feet from the
vehicle.
If unable to store the Intelligent Key more than 15 feet from the vehicle (for example, when a vehicle is on
display in the showroom), the following steps will prevent the BCM from continuing to “ping” the Intelligent Key:

Disable the welcome light function using the on-board methods outlined in this bulletin, or

Disable the welcome light function using the CONSULT-III plus methods outlined in this bulletin.
NOTE: If an Intelligent key is routinely stored within 15 feet of a vehicle while it is in dealer inventory, the
Intelligent Key battery should be replaced before the vehicle is delivered to the customer. This will ensure the
customer receives Intelligent Keys without premature discharge. Intelligent Key batteries replaced for this
reason are not covered under warranty.
Infiniti Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are properly trained

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.
