The 2018–2021 Tundra uses the same key setup, so everything on this page applies to those years too. The full picture is on the Toyota Tundra key guide.

Same key system as the 2018–2021 Tundra
Toyota kept the Tundra's key system unchanged across 2018–2021, so everything about replacing a 2019 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 Toyota Tundra 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 Toyota programming in general on our Toyota key page.
