The de Ville was originally a trim level and later a model of General Motors' Cadillac marque. The first car to bear the name was the 1949 Coupe de Ville, a prestige trim level of the Series 62 luxury coupe. 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. The last model to be formally known as a De Ville was the 2005 Cadillac DeVille, a full-size sedan, the largest car in the Cadillac model range at the time. Although this vehicle is no longer produced, ProgramYourRemote.com will continue to provide the keyless entry remote fob smart key programming instructions and information.
