The 2006–2013 Impala uses the same key setup, so everything on this page applies to those years too. The full picture is on the Chevrolet Impala key guide.

2009 Chevrolet Impala: key facts

Same key system as the 2006–2013 Impala

Chevrolet kept the Impala's key system unchanged across 2006–2013, so everything about replacing a 2009 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 Impala 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.
