Same key system as the 2018–2020 Traverse

Chevrolet kept the Traverse's key system unchanged across 2018–2020, 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 Chevrolet Traverse 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 Chevrolet programming in general on our Chevrolet key page.
