IF YOU CONFIRM
All “hands free” functions of the Intelligent Key (I-Key) do not work. For example, the doors will not lock or
unlock when pressing either front door request switch.
NOTE:

The issue of all I-Key “hands free” functions not working may occur intermittently or all the time.

The message “No Key Detected” or similar may show on the Vehicle Information Display (located
in the combination meter).

All I-Key remote button functions (door lock/unlock, etc.) WILL work normally when all I-Key
“hands free” functions are NOT working.
ACTION
1. Inspect the I-Key’s battery on its negative contact side.
2. If excessive scratching is found (see example on the next page), replace the battery.
3. Verify all I-Key functions (both “hands free” and remote) work properly after battery replacement.
NOTE: Do NOT replace the BCM, I-Key, or other parts for the issue described under IF YOU CONFIRM,
should it occur.

a described condition may apply to a particular vehicle, DO NOT assume that it does. See your Infiniti dealer to determine if this
applies to your vehicle.
