The Nissan Altima is a mid-size car manufactured by Nissan. The very first Altima rolled off the assembly line on June 15, 1992, as a 1993 model. Some model years of the Nissan Altima 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 Nissan Altima are not onboard programmable and require special equipment in order to program the keyless entry remote fob smart key.
