The 2011–2016 Elantra uses the same key setup, so everything on this page applies to those years too. The full picture is on the Hyundai Elantra key guide.

2016 Hyundai Elantra: key facts

Key type: Mechanical (no chip)
Push-to-start: No
Transponder chip: ID46 (PCF7936/PCF7952) on immobilizer-equipped trims
Programming: NONE
All keys lost: We can originate new keys on site

On Hyundai's official anti-theft software-update list (2011-2022 Elantra): base turn-key trims shipped with NO immobilizer, so any properly cut metal copy starts the car. Limited/push-button trims do carry an ID46 smart-key immobilizer and program via OBD. We confirm trim on the vehicle.

Same key system as the 2011–2016 Elantra

Hyundai kept the Elantra's key system unchanged across 2011–2016, so everything about replacing a 2016 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 Hyundai Elantra 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 Hyundai programming in general on our Hyundai key page.
