[s-cars] Re-keying 95.5 and up side cut lock cylinders

[Joshua van Tol]

Does anyone know how to re-key a side cut lock cylinder, as used in a 
1995.5 S6? Some know nothing former mechanic put in the old style lock, 
so I've got a new lock cylinder here, ready to install, but I've got to 
figure out how to re-key it to match the existing keys. I've been able 
to get the end piece that turns the ignition switch out by driving out 
the roll pin, but I can't for the life of me figure out how to 
disassemble the lock cylinder.

Any clues?
