Hyundai Sonata Key Replacement in Gaithersburg
Hyundai Sonata key systems vary by model year and trim. Keyed ignition and push-to-start versions exist, so a key that looks similar may not be the right match for your vehicle. We confirm the exact key using the year, trim, and VIN before we proceed.
Our mobile locksmith comes to your car, and the key cutting machine is in the service van. That means the key work happens on site rather than at a storefront. For more about our broader Hyundai key replacement service, visit the Hyundai service page.
Model year and trim vary — keyed ignition
Some Sonata versions use a keyed ignition. The correct replacement depends on your vehicle’s year and trim, so we check the VIN before identifying the key.
Model year and trim vary — push-to-start
Other Sonata versions use push-to-start keys. The matching key depends on the specific vehicle; we use the year, trim, and VIN to confirm what it needs.
