Audi S4 Keyless Entry Remote Fob Smart Key Programming Instructions

The Audi S4 is the high performance variant of Audi's compact executive car A4. The original Audi S4, built from 1991 until 1994, was a performance-oriented version of Audi's 100 saloon/sedan. All subsequent S4s since 1997 have been based on the Audi A4; and as the A4 has evolved from one generation to the next, so has the S4. Onboard manual keyless entry remote fob smart key programming is not available on the S4, meaning that special equipment, and not just programming instructions, will be needed to program a keyless entry remote fob smart key to the Audi S4.
