I am having the same problem right now and it is 2018 I have a 07 M35 and I could not find the part anywhere I was able to get it started only for it to not start again luckily I had it at home and it has been sitting for the last 2 months. I found the part on Ebay but now I am hearing that I will have to take the car to the dealership because it still will have to be reprogrammed. I called Infiniti and they told me parts and labor would be 1785. I do not know how much they will charge just to reprogram. I guess I will have to call. I messaged a mechanic online and he told me that it would not have to be reprogrammed does anyone know if this is true or not?
I believe it has to be preprogrammed. Without calling a dealership, I would assume it is their standard "reprogramming charge" be it keys or any other items that communicate to enable the car to start. Approx $125 around here.
It would be worthwhile to call a locksmith as well, but their costs are usually pretty high (almost as much as the dealer) from my recent inquiries.
As for the parts and saving on labor, see if going over these 3 threads gives you any ideas:

If you go the replace-at-home route, let me know and I'll describe a way to trick the car into starting with the "new" parts for that one trip to the dealer to get it programmed.
