About G80 Keys
Verified key reference for the Genesis G80 — 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 |
|---|---|---|---|---|
| Genesis G80 (1st gen, DH carryover) | 2017–2020 | Smart proximity key | Hitag3 ID47 | SY5DHFNA433 family (“G80 2015+”) — confirm by VIN |
| Genesis G80 (2nd gen, RG3) | 2021–2025 | Smart proximity key (6-btn) | Hitag3 ID47 | FCC TQ8-FOB-4F36, PN 95440-T1010, 434 MHz |
| Genesis G80 (2nd gen, RG3) | 2022–2025 | Smart proximity key (8-btn) | Hitag3 ID47 | FCC TQ8-FOB-4F53, PN 95440-T1210, 434 MHz |
Security System & Immobilizer
Every Genesis-brand smart key runs the Hitag3 ID47 family; newer models add Digital Key phone credentials that still depend on an enrolled physical fob.
On the G80 specifically we see: Hitag3 ID47. A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Genesis G80 Key FAQ
I lost the only key to my G80. 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 G80 is push-to-start — can you program that outside the dealer?
Yes. Late models (2022–2025) use a proximity smart key on Hitag3 ID47 — we carry the fobs and the programmer, and we cut the emergency blade.
Do you still stock keys for older G80s?
Yes — back to the 2017–2020 generation (smart proximity key), and a fresh code-cut key beats any copy of a worn original.
