About Murano Keys
The table below is our verified key reference for the Nissan Murano — 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 |
|---|---|---|---|---|
| Murano | 2009–2014 | Intelligent Key smart-proximity | Philips Crypto 2 / Hitag 2 / ID46 / PCF7952 | DA34 emergency insert |
| Murano | 2009–2014 | KR55WK49622 | 315 MHz | 285E3-1AA7B |
| Murano | 2015–2023 | Intelligent Key smart-proximity | Hitag AES / ID4A / NXP PCF7953M, NCF29A1M | DA34 emergency insert |
| Murano | 2015–2023 | KR5S180144014 (2015–2018) → KR5TXN7 (2019–2024) | 433 MHz | 285E3-5AA3D / 285E3-9UF7B |
Security System & Immobilizer
Nissan’s NATS immobilizer dates to the late 1990s, evolving from early transponders through ID46 chips to the Intelligent Key proximity system that made push-button start mainstream.
On the Murano specifically, the immobilizer families we see are: Philips Crypto 2 / Hitag 2 / ID46 / PCF7952, 315 MHz, Hitag AES / ID4A / NXP PCF7953M, NCF29A1M, 433 MHz. 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.

Nissan Murano Key FAQ
I lost the only key to my Murano. 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 Murano call.
Will a hardware-store copy start my Murano?
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.
My Murano is older — do you still stock keys for it?
Yes. We carry blanks and chips going back to the 2009–2014 generation (intelligent key smart-proximity), and a code-cut fresh key usually turns a worn lock better than any copy of your worn key.
