The Roadmaster was an automobile built by the Buick division of General Motors. Roadmasters produced between 1936 and 1958 were built on Buick's longest non-limousine wheelbase and shared their basic structure with entry-level Cadillac. At that time, there was no need for keyless entry remote fob smart key programming instructions, as the keyless entry remote fob smart key option was not yet available. Between 1946 and 1957 the Roadmaster served as Buick's flagship, and when it was resurrected for the 1991 through 1996 model years it was the marque's largest vehicle. Although the Buick Roadmaster is no longer produced, ProgramYourRemote.com will continue to provide the keyless entry remote fob smart key programming instructions and information.
