About QX55 Keys
Verified key reference for the Infiniti QX55 — 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 |
|---|---|---|---|---|
| QX55 | 2022–2025 | Smart key (Intelligent Key, push-button) | Hitag AES ID4A (PCF7953-class) | NSN14 (DA34) |
Security System & Immobilizer
Infiniti runs Nissan’s NATS immobilizer and standardized Intelligent Key proximity fobs early.
On the QX55 specifically we see: Hitag AES ID4A (PCF7953-class). A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Infiniti QX55 Key FAQ
I lost the only key to my QX55. 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 QX55 is push-to-start — can you program that outside the dealer?
Yes. Late models (2022–2025) use a proximity smart key on Hitag AES ID4A (PCF7953-class) — we carry the fobs and the programmer, and we cut the emergency blade.
