BMW X3 Keyless Entry Remote Fob Smart Key Programming Instructions

The BMW X3 is a compact executive/entry-level luxury crossover marketed by German automaker BMW since 2003. Based on the BMW 3 Series platform, and now in its second generation, BMW markets the crossover as a Sports Activity Vehicle, the company's proprietary descriptor for its X-line of vehicles. Onboard manual keyless entry remote fob smart key programming is available on some model years of the X3, meaning that programming can be done using programming instructions only, while other years will require special equipment along with the programming instructions to program keyless entry remote fob smart keys.
