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.

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.

Which key does your year have?

  • 2001–2006: Mechanical / non-transponder — VATS-PassKey (no chip) (B102 / B106)

Our Envoy Key Services


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.

How fast can you reach my Envoy in DFW?

We dispatch the nearest mobile unit across the whole metroplex, 24/7. Call (214) 717-6398 with your location and we’ll give you an honest ETA.
