Hyundai Kona Key Replacement
Hyundai Konas have been on Dallas–Fort Worth roads since the 2018 era, and across 2 key generations this model has used 2 different key systems — smart-proximity (gas); transponder (mechanical-key variant). Whichever yours is, DFW Keys 4 Cars cuts and programs it at your location, 24/7: spare keys, lost-everything replacements, fob programming, and lockouts. Call (214) 717-6398.
About Kona Keys
The table below is our verified key reference for the Hyundai Kona — model years, key types, and the transponder/immobilizer family each generation uses. Generations overlap at boundary years, so we always confirm the exact part by VIN before dispatching.
| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |
|---|---|---|---|---|
| Kona | 2018–2023 | Smart-proximity (gas) | Texas DST AES 128-bit (Smartra 3) — confirm by VIN | HY18R (emergency insert) |
| Accent / Veloster / Kona | 2019–2023 | Transponder (mechanical-key variant) | Philips Crypto 3 / ID47 / Hitag 3 | HY18R |
Security System & Immobilizer
Hyundai moved from ID46-era transponders and flip keys to Hitag3 ID47 smart keys, with the newest models on ID4A encryption. Chip family determines the programming path, and we match it by VIN.
On the Kona specifically, the immobilizer families we see are: Texas DST AES 128-bit (Smartra 3) — confirm by VIN, Philips Crypto 3 / ID47 / Hitag 3. A key that is cut correctly but not programmed to this system will turn the locks and never start the engine — programming is the half of the job that matters.

Hyundai Kona Key FAQ
I lost the only key to my Kona. What now?
We come to the vehicle, verify ownership, cut a new key from the VIN, and program it on-site. No tow, no dealer wait — this is our most common Kona call.
Will a hardware-store copy start my Kona?
It will open the doors and nothing else on transponder-era cars — the chip inside the key must be programmed to the immobilizer, which is the part we do curbside.
