Kia Optima/K5 Key System Overview

The Kia Optima/K5 (2013-2026) 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. We cut the key, program the chip to your Kia Optima/K5's computer, test door locks, ignition, and trunk, then hand you a working key.
