APPLIED VEHICLES: 2015 Q50 and Q50 Hybrid (V37)

SERVICE INFORMATION
If it appears for ONLY ONE OF the Intelligent Keys that all “RKE” lock/unlock/panic/trunk button functions of
that specific Intelligent Key do not work
BUT
The doors will lock and unlock when pressing either front door request switch while using that particular
Intelligent Key (see Figure 1 below)
Hands-free functions such as request switch
will operate as designed
Figure 1
AND
All the other Intelligent Keys for that vehicle function normally
THEN
That specific Intelligent Key may have become De-synchronized with the vehicle.
NOTE:
 Intelligent Key De-synchronization may occur if the Intelligent Key is not used for extended periods of
time or if key was not operating due to low battery condition and the battery has been replaced.
 Do NOT replace the BCM, Intelligent Key, or any other parts if an Intelligent Key only needs to be resynchronized.

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.

To test Intelligent Key synchronization:
1. Place the incident Intelligent Key outside the vehicle. (Minimum distance 10 feet) to avoid detection of the
Key by the vehicle. See Figure 2 below.

NOTE: Steps 2a, b, & c MUST be done in close time and sequence together in order for test to be performed
correctly.
2a. Open the door, enter the vehicle, and then close the door. Then immediately perform step 2b.

At this time, due to no Intelligent Key in or around the vehicle, the BCM will activate only the ignition
switch antenna.
Ignition switch antenna will become active
and will transmit a signal to detect any
Intelligent Key in range.
Figure 3
2b. WITHIN 30 SECONDS of step 2 above, FIRST have an associate hand the Intelligent Key to you, THEN
immediately perform step 2c.
Have an associate deliver the incident Key
WITHOUT HAVING TO OPEN THE DOOR.
Figure 4
2c. Place the Intelligent Key next to the Ignition Button as shown in Figure 5 below (emblems align with center
of buttons). Do not depress the Ignition Button.
Place Intelligent Key next to Ignition Button
and wait for tones.
Figure 5

If two short tones are heard the Intelligent Key had become De-synchronized. The Intelligent Key is
now re-synchronized and should now function normally. See step 4/Figure 6 (next page).

If no tones are heard and the Intelligent Key buttons still do not work refer to ASIST or the applicable
Electronic Service Manual for further diagnosis.
3. At this time, the Combination Meter information area will display the PUSH BRAKE AND START BUTTON
TO DRIVE welcome screen (Figure 7, next page).
