The 2025–2026 Odyssey uses the same key setup, so everything on this page applies to those years too. The full picture is on the Honda Odyssey key guide.
2026 Honda Odyssey: key facts
- Key type
- Smart / proximity key
- Push-to-start
- Yes
- Transponder chip
- Varies by trim — we confirm by VIN
- Programming

- All keys lost
- Depends on trim — call to confirm
Catalogs carry the ID47 smart-key listing through 2026, but we have not verified these newest model years individually — confirmed by VIN and current tool coverage before quoting.
Same key system as the 2025–2026 Odyssey
Honda kept the Odyssey's key system unchanged across 2025–2026, so everything about replacing a 2026 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 Odyssey 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.
