Infiniti QX56 Key Replacement
Infiniti QX56s have been on Dallas–Fort Worth roads since the 2004 era, and across 2 key generations this model has used 2 different key systems — transponder (04–07) → smart key (08–10); smart key (intelligent key, push-button). Whichever yours is, DFW Keys 4 Cars cuts and programs it at your location, 24/7: spare keys, lost-everything replacements, fob programming, and lockouts. Call (214) 717-6398.
About QX56 Keys
The table below is our verified key reference for the Infiniti QX56 — model years, key types, and the transponder/immobilizer family each generation uses. Generations overlap at boundary years, and trim levels (keyed vs. push-to-start) can differ within the same year, so we always confirm the exact part by VIN before dispatching.
| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |
|---|---|---|---|---|
| QX56 (1st gen) | 2004–2010 | Transponder (04–07) → smart key (08–10) | Philips ID46 (PCF7936) | NSN14 (DA34) |
| QX56 (2nd gen) | 2011–2013 | Smart key (Intelligent Key, push-button) | Philips ID46 (PCF7952A) | NSN14 (DA34) |
Security System & Immobilizer
Infiniti runs Nissan’s NATS immobilizer and was among the first to standardize Intelligent Key proximity fobs — all programmable on-site with current equipment.
On the QX56 specifically, the immobilizer families we see are: Philips ID46 (PCF7936), Philips ID46 (PCF7952A). 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.
Which key does your year have?
- 2004–2010: Transponder (04–07) → smart key (08–10) — Philips ID46 (PCF7936) (NSN14 (DA34))
- 2011–2013: Smart key (Intelligent Key, push-button) — Philips ID46 (PCF7952A) (NSN14 (DA34))

Infiniti QX56 Key FAQ
I lost the only key to my QX56. 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 QX56 call.
My QX56 is push-to-start. Can you really program that outside the dealer?
Yes. Late-model QX56s (2011–2013) use a proximity smart key on the Philips ID46 (PCF7952A) system — our trucks carry the fobs and the programmer. We cut the emergency blade too.
