The 2005–2009 Mustang uses the same key setup, so everything on this page applies to those years too. The full picture is on the Ford Mustang key guide.

Same key system as the 2005–2009 Mustang

Ford kept the Mustang's key system unchanged across 2005–2009, so everything about replacing a 2008 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 Ford Mustang 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 Ford programming in general on our Ford key page.
