I found a really nice 2017 Sentra S with 65k miles and purchased it. The dealership only had one key and it’s a regular key not a key fob. I had a 2012 Sentra a couple years ago and it had a fob. I assume this 2017 should have a fob. I’m wondering how to get one? I’ve seen them for sale on Amazon but I’d need programming and as I have no original I’m not sure what to do. If I buy a blank fob set from Amazon could it be programmed somehow at my Nissan dealer even though I don’t have a fob now? Did they sell any 2017 with keys only?

Any direction on what I should do would be very appreciated. Thank you.
