The 2017–2024 Ridgeline uses the same key setup, so everything on this page applies to those years too. The full picture is on the Honda Ridgeline key guide.

Same key system as the 2017–2024 Ridgeline

Honda kept the Ridgeline's key system unchanged across 2017–2024, so everything about replacing a 2018 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 Honda Ridgeline 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 Honda programming in general on our Honda key page.
