The Infiniti QX70
(formerly called the Infiniti FX
until 2013) is a mid-sized
/ lengthened compact luxury crossover SUV
. The nameplates FX35 and FX45 refer to the two available engines. Some model years of the Infiniti FX45 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 are not onboard programmable and require special equipment in order to program the keyless entry remote fob smart key.
