The BMW 4 Series is a range of coupé, convertible and fastback models manufactured by the German automaker BMW since 2013. It was unveiled at the North American International Auto Show in January 2013 in Detroit. Onboard manual keyless entry remote fob smart key programming is not available on the BMW 4 Series, meaning that special equipment, and not just programming instructions, will be needed to program your keyless entry remote fob smart key.
