About NSX Keys
Verified key reference for the Acura NSX — 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 |
|---|---|---|---|---|
| NSX | 1997–2005 | Transponder | Megamos ID13 | older Honda keyway |
| NSX | 2017–present | Smart key (proximity) | Hitag3 ID47 | HON66 |
Security System & Immobilizer
Acura runs Honda’s immobilizer architecture — ID46-era transponders through current Smart Entry proximity fobs.
On the NSX specifically we see: Megamos ID13, 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.
Which key does your year have?
- 1997–2005: Transponder — Megamos ID13 (older Honda keyway)

Acura NSX Key FAQ
I lost the only key to my NSX. 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 NSX is push-to-start — can you program that outside the dealer?
Yes. Late models (2017–present) use a proximity smart key on Hitag3 ID47 — we carry the fobs and the programmer, and we cut the emergency blade.
