Same key system as the 2015–2022 Colorado

Chevrolet kept the Colorado's key system unchanged across 2015–2022, so everything about replacing a 2021 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 Colorado 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.
