Immobilizer handshakes and key fob registration protocols are controlled by the BCM non-volatile EEPROM memory and secure cryptographic rolling codes, preventing unauthorized programming without factory diagnostic equipment.
How to Fix It:
-
Perform Professional Key Programming: Take the vehicle and all available key fobs to an authorized Nissan dealer or certified automotive locksmith equipped with Nissan CONSULT diagnostic software to program new fobs securely.
-
Purge Lost Keys: Ensure the technician erases lost or stolen key transponder IDs from the BCM memory during the programming session so missing fobs can no longer start the vehicle.
-
Test All Fob Functions: Verify that door lock/unlock requests, trunk release, panic alarm, and push-button ignition functions operate correctly for every newly registered key fob before leaving the service center.
