GMC Envoy key types & programming facts
2002-2009 GMC Envoy models use a conventional metal ignition key and a separate 3‑button keyless entry remote that must be programmed to the vehicle.

Programming does not normally require special diagnostic equipment but all remotes must be programmed in the same session.

- standard metal ignition key (non-transponder) with separate keyless-entry remote fob (2002-2009)

How we validate this guide
Year coverage comes from our consolidated vehicle programming dataset. Route-level programming status is reviewed against internal route sheets and available manufacturer, security-access, and professional tool references. Exact button sequences are marked source-verified only when we have year/equipment-specific support; where a year is labeled “route verified, steps vary,” we confirm the exact fob, trim, and prompts before programming.
