The Infiniti Q45 was a full-size luxury car sold by Nissan's Infiniti marque from 1989 until 2006. It is a rear wheel drive, four-door sedan powered by a V8 engine. Exports of the Q45 ceased after 2006. Some model years of the Infiniti Q45 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.
