The 2007–2019 Sentra uses the same key setup, so everything on this page applies to those years too. The full picture is on the Nissan Sentra key guide.

Same key system as the 2007–2019 Sentra

Nissan kept the Sentra's key system unchanged across 2007–2019, so everything about replacing a 2015 key — blanks, programming, and what happens if every key is lost — matches the rest of that run. The full year-by-year breakdown lives in our Nissan Sentra key guide.

What drives the price is the key type, whether you still have a working key, and where the car is parked. There's more on Nissan programming in general on our Nissan key page.
