Hyundai Sonata Key System Overview

The Hyundai Sonata (2012-2026) has used multiple key technologies across its production years. Earlier model years feature transponder chip keys that must be cut to the correct profile and programmed to match the vehicle's immobilizer. Newer versions use smart key proximity fobs with push-button start. This model supports Transponder Key, Smart Key, Key Fob. The process: cut the blade, pair the chip to your Hyundai Sonata, verify start and lock functions, done. Usually under 30 minutes.
