A reader called to ask what the correct replacement remote transmitter is for a 2010 Nissan Armada with factory keyless entry. Before giving her an answer, we had to ask if she had a keyed ignition or push-button start. She answered that she has a keyed ignition and a stand-alone keyfob. The correct replacement remote for this application is a 4-button keyfob with FCC ID KBRASTU15 and Nissan part number 28268-ZE10A or 28268-ZE10B.
The system that uses this part is user-programmable.
