Which Key Does the Hyundai Ioniq Actually Use?
Depending on your trim year and package, the Ioniq uses one of three key types: a basic Plastic Head Key, a Remote Flip Key, or a proximity-based Smart Key — each with different button counts (4, 5, or 7 buttons) and operating frequencies of 433 or 434 MHz. We stock all seven documented variants for this model, so there's no guessing or waiting on a special order. If you're unsure which format your Ioniq requires, our tech can verify on-site by VIN before cutting or programming anything. Learn more about how programming differs by key type on our key fob programming page.
What Happens If You've Lost All Ioniq Keys?
Losing every key to your Ioniq is a worst-case but fully solvable situation — it does require an all-keys-lost programming procedure, which takes more time than adding a spare to an existing working key. Our mobile units in Las Vegas carry the specialized equipment to perform this procedure on-site, including for Smart Key trims that require secure pairing through the vehicle's immobilizer system. You will not need to tow the car to a Hyundai dealer; we come to your location 24 hours a day across the Las Vegas valley. Check our 24-hour locksmith page if you need immediate dispatch.
What Changes the Price and How to Get It Done Fast
Our Ioniq key parts start at roughly $4 for the component alone, but the all-in installed price — cutting, programming, and on-site labor — is shown above and is firm with no hidden fees. The main factors that affect total cost are key type (Smart Key systems require more programming steps than a Flip Key), whether you have a working key to add to, and time of service. To move fastest, have your VIN and proof of ownership ready when you call; our tech can pre-stage the correct blank for your specific FCC ID before arriving.
