The "M" nameplate has been used on various mid-luxury cars from the Infiniti luxury division of Nissan. Following a redesign in 2006, the M series was reborn as the V6-powered M35 and V8-equipped M45. The M35 was finally succeeded by the redesigned M37 for the 2011 model year. Models do not have keyless entry remote fob smart keys that are onboard programmable and therefore require special equipment in order to program the keyless entry remote fob smart key.
