Look up Nissan key learning procedure and reset fobs. I had similar on my Silverado, key simply stopped working, and it fixed it every time. That would be the first step. If it does not help, then yes, sure, keylees entry does have fuses but they will be for door locks and for trunk.
Btw, pop fobs open completely and check buttons area. It goes oxydized and simple cleaning with pencil eraser does the trick.
