The GMC Envoy is an SUV from the GMC marque of General Motors. The Envoy nameplate reappeared in the GMC line of vehicles from 2002 through 2009 as a standalone model until the unibody 5-seat Terrain and 7-seat Acadia crossovers replaced the standard and XL models, respectively; the Envoy sold alongside the Acadia from 2007-09. The GMC Envoy has keyless entry remote fob smart keys that are onboard programmable, which means a person can program the keyless entry remote fob smart key with no special equipment other than the keyless entry remote fob smart key programming instructions.
