Pro tip #1: You go to Nissan for parts. You DO NOT go to Nissan to work on or service your car (DIY)
Pro tip #2: If you do need Nissan to do something on your car (key or BCM program etc), first thing to state over the phone is what you need done on your car. If they won't touch "imports" (lol @ hypocrite), go to a Nissan Dealership that will.
