About 370Z Keys
Verified key reference for the Nissan 370Z — 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 |
|---|---|---|---|---|
| 370Z | 2009–2020 | Intelligent Key smart-proximity | Philips Crypto 2 / Hitag 2 / ID46 / PCF7952 | DA34 emergency insert |
| 370Z | 2009–2020 | KR55WK49622; early KR55WK48903 | 315 MHz | 285E3-1ET5D |
Security System & Immobilizer
Nissan’s NATS immobilizer evolved from early transponders through ID46 chips to the Intelligent Key proximity system.
On the 370Z specifically we see: Philips Crypto 2 / Hitag 2 / ID46 / PCF7952, 315 MHz. A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Nissan 370Z Key FAQ
I lost the only key to my 370Z. 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.
Will a hardware-store copy start my 370Z?
On transponder-era cars it opens doors and nothing else — the chip must be programmed to the immobilizer, which is what we do curbside.
