The Infiniti M45 was designed in 2000 at the Nissan Technical Center (NTC) in Atsugi, Japan. It was sold from model year 2003 until 2010. Some model years of the Infiniti M45 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 Infiniti M45 are not onboard programmable and require special equipment in order to program the keyless entry remote fob smart key.
