The Buick Enclave is a full-size luxury crossover SUV launched in May 2007 as a 2008 model by the Buick division of General Motors. The Buick Enclave, GMC Acadia, and Chevrolet Traverse all share the GM Lambda platform. Some model years of the Buick Enclave have 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. However, other model years of the Buick Enclave are not onboard programmable and require special equipment in order to program the keyless entry remote fob smart key.
