The 2021–2024 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.

2022 Kia Sorento: key facts

Key type: Smart / proximity key
Push-to-start: Yes
Transponder chip: 4A (NXP Hitag AES)
Programming: OBD
All keys lost: We can originate new keys on site

Most trims: push-button start with a 4A Hitag-AES smart key. The 2021-2022 Sorento still appears in the Hyundai/Kia theft class list, which covers turn-key cars without immobilizers — base turn-key cars exist and need no transponder programming; we confirm per VIN. Smart-key OBD programming may require a Kia PIN depending on the tool. Catalogs also list a Texas AES ID75 variant for some MQ4 fobs, so we confirm the fob part number.

Same key system as the 2021–2024 Sorento

Kia kept the Sorento's key system unchanged across 2021–2024, so everything about replacing a 2022 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.
