The Saturn Vue is a compact crossover SUV that was sold by General Motors' Saturn marque, and at one time was Saturn's best-selling model. Some model years of the Saturn Vue have keyless entry remote fob smart keys that are onboard programmable,meaning 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. Other model years of the Saturn Vue, however, are not on-board programmable and require special equipment in order to program the keyless entry remote fob smart key.
