Kia Optima / K5 key replacement and programming
Kia sold this mid-size sedan as Optima through 2020 and as K5 from 2021. The name change came with a redesign, so an Optima key won’t fit a K5.

Important compatibility notice — final key compatibility must be confirmed
The key images, vehicle models, and year ranges shown on this page are provided as a general identification guide and may not apply to every vehicle. The manufacturer may use different key systems within the same model year depending on trim level, production date, manufacturing location, ignition type, and factory equipment. Final compatibility must be confirmed using the vehicle’s VIN, ignition type, existing key or fob, and vehicle information before service. The images are representative examples and do not guarantee an exact visual match.
A current registration or title and matching government-issued photo identification must be verified before automotive key, lock, or immobilizer service is performed.
