The Infiniti QX70 (called the Infiniti FX from 2003 through 2013) is a mid-size luxury crossover SUV produced by the Nissan-owned Infiniti luxury vehicle brand. Some model years of the Infiniti FX35 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.
