About Envoy Keys
The table below is our verified key reference for the GMC Envoy — 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 |
|---|---|---|---|---|
| Envoy | 2001–2006 | Mechanical / non-transponder | VATS-PassKey (no chip) | B102 / B106 |
| GMC ENVOY | 2001-2006 | VATS / PassKey Anti Theft System | ||
| Envoy | 2006–2009 | Transponder | Philips Crypto 2 / Hitag2 / ID46 (PCF7936AS) | B111 (HU100) |
| GMC ENVOY | 2006-2009 | Transponder Philips Crypto 2 / Hitag2 / ID46 ⇆ PCF7936AS / JMA : TP12GM / SILCA: T14 / CN3 |
Security System & Immobilizer
GMC trucks follow GM’s security ladder — VATS, PassLock, PK3/PK3+ transponders, ID46 Circle+ keys, and modern proximity fobs — each with its own programming path our equipment covers.
On the Envoy specifically, the immobilizer families we see are: VATS-PassKey (no chip), Philips Crypto 2 / Hitag2 / ID46 (PCF7936AS). 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.

GMC Envoy Key FAQ
I lost the only key to my Envoy. 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 Envoy call.
Will a hardware-store copy start my Envoy?
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 Envoy is older — do you still stock keys for it?
Yes. We carry blanks and chips going back to the 2001–2006 generation (mechanical / non-transponder), and a code-cut fresh key usually turns a worn lock better than any copy of your worn key.
