How to Reprogam the Switchblade Key
 

I want to thank Jared for the following link. Jack Daniels Audi wanted $128
to reprogram my fob, after I replaced the batteries.

That is one of the dumbest thingI have ever heard a dealership charge someone... it explains how to reprogram it in the audi manual.

What is in the manual doesn't always work. After changing batteries
the memory in the fob might get wiped out. This link works. I printed
it and added it to my owner's manual.
