Hyundai Sonata key replacement and programming
Sonata moved to a Smart Key on upper trims earlier than Elantra, and later generations made push-button start common across the range.
Sonata key systems by model year
Year ranges follow Sonata generations and are approximate. Trim, build date and factory options can change the system within a year, so we confirm it from your VIN before dispatch.

Lost every Sonata key?
If no working key remains, we can make and program a new key for many Hyundai vehicles at the car. The job depends on whether your vehicle has an immobilizer and which key system it uses, so we confirm both from your VIN first.
What to send for a Sonata key quote
- Model year, from the registration or title
- Turn-key ignition or push-button start
- Whether any working key remains
- A photo of the key or ignition, if you have one
Most Sonata calls we take are in Burbank and nearby Glendale; we work wherever the vehicle is parked. Glendale service area
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.
