The 2025–2026 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.
2026 Kia Sorento: key facts
- Key type
- Smart / proximity key
- Push-to-start
- Yes
- Transponder chip
- 4A (NXP Hitag AES)
- Programming
- OBD
- All keys lost
- Depends on trim — call to confirm
Push-button start with the 4A Hitag-AES smart key per catalogs (transpondery.com lists the MQ4 through 2026), but we confirm the fob part number and current all-keys-lost tool coverage per job. OBD programming; a Kia PIN may be required.
Same key system as the 2025–2026 Sorento
Kia kept the Sorento'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 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.
