The 2016–2018 Sorento uses the same key setup, so everything on this page applies to those years too. The full picture is on the Kia Sorento key guide.

2018 Kia Sorento: key facts

Key type: Mechanical (no chip)
Push-to-start: No
Transponder chip: 47 (Hitag 3) — smart-key trims only
Programming: OBD
All keys lost: We can originate new keys on site

Base trims: turn-key with NO immobilizer (theft class list). US smart-key fob TQ8-FOB-4F06 (95440-C6000) is listed as Hitag 3 / ID47 by US vendors, but transpondery.com lists ID46 or DST80 for early global UM cars — we confirm by fob part number before quoting.

Same key system as the 2016–2018 Sorento

Kia kept the Sorento's key system unchanged across 2016–2018, 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 Kia Sorento 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 Kia programming in general on our Kia key page.
