About Nexo Keys
Verified key reference for the Hyundai Nexo — model years, key types, and the transponder/immobilizer each generation uses. Boundary years can overlap; we confirm the exact part by VIN before dispatching.
| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |
|---|---|---|---|---|
| Nexo (FCEV) | 2019–2021 | Smart-proximity (FCC TQ8-FOB-4F20) | Philips ID47 / Hitag 3 | HY18R (emergency insert) |
Security System & Immobilizer
Hyundai moved from ID46-era transponders and flip keys to Hitag3 ID47 smart keys, with ID4A on the newest models.
On the Nexo specifically we see: Philips ID47 / Hitag 3. A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Hyundai Nexo Key FAQ
I lost the only key to my Nexo. 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.
My Nexo is push-to-start — can you program that outside the dealer?
Yes. Late models (2019–2021) use a proximity smart key on Philips ID47 / Hitag 3 — we carry the fobs and the programmer, and we cut the emergency blade.
