The Chevrolet Traverse is a seven or eight seat, full-size crossover SUV built on the GM Lambda platform that underpins the GMC Acadia and Buick Enclave. The 2009 Chevrolet Traverse debuted at the 2008 Chicago Auto Show and arrived at every dealer in October 2008. Some model years of the Chevrolet Traverse have keyless entry remote key fobs that are onboard programmable, which means a person can program the keyless entry remote key fob with no special equipment other than the keyless entry remote key fob programming instructions. While other model years of the Chevrolet Traverse are not on-board programmable and require special equipment in order to program the keyless entry remote fob smart key.
