The 2000–2004 Pathfinder uses the same key setup, so everything on this page applies to those years too. The full picture is on the Nissan Pathfinder key guide.

Nissan kept the Pathfinder's key system unchanged across 2000–2004, so everything about replacing a 2003 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 Pathfinder 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.
