The 2015–2020 Fit uses the same key setup, so everything on this page applies to those years too. The full picture is on the Honda Fit key guide.

2018 Honda Fit: key facts

Key type: Remote-head key
Push-to-start: No
Transponder chip: G (ID47, Hitag 3)
Programming: OBD
All keys lost: We can originate new keys on site

LX keeps a keyed ignition (MLBHLIK6-1T G-chip remote-head key); EX and above use the KR5V1X smart fob (ID47) with push-button start — pushToStart reflects the keyed base trim. There was no 2014 US model year.

Same key system as the 2015–2020 Fit

Honda kept the Fit's key system unchanged across 2015–2020, 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 Fit 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.
