The Buick LeSabre is a full-size upscale car made by the Buick division of General Motors from 1959-2005. For many years, the LeSabre was considered the entry level full-size Buick, carrying the lowest base price in the Buick lineup. Some model years of the Buick LeSabre 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 LeSabre are not onboard programmable and require special equipment in order to program the keyless entry remote fob smart key.
