Claim:
A mogul cylinder assembly comprising: a generally-cylindrical lock housing mogul having a front surface and a principal axis and having a cylinder bore disposed therein having a principal axis parallel to, and offset from, the principal axis of the lock housing mogul and an inner surface, a first driver pin bore extending radially from, and orthogonal to, the principal axis of the cylinder bore, a second driver pin bore extending radially from, and orthogonal to, the principal axis of the cylinder bore and orthogonal to the first pin bore, and a third driver pin bore extending radially from, and orthogonal to, the principal axis of the cylinder bore, wherein the first driver pin bore is disposed counterclockwise from the second driver pin bore radially about the principal axis of the cylinder bore and the third driver pin bore is disposed clockwise from the second driver pin bore radially about the principal axis of the cylinder bore; a cylinder blank disposed within the cylinder bore and having a principal axis aligned to the principal axis of the cylinder bore, a first pass key pin bore aligned to the first driver pin bore of the lock housing mogul, a second pass key pin bore aligned to the second driver pin bore of the lock housing mogul, and a third pass key pin bore aligned to the third driver pin bore of the lock housing mogul; a first driver pin disposed within the first driver pin bore; a first pass key pin, having a conical shaped end, disposed within the first pass key pin bore; a second driver pin disposed within the second driver pin bore; and a second pass key pin, having a conical shaped end, disposed within the second pass key pin bore; a first hardened dowel pin disposed between the first driver pin bore and an escutcheon of the lock housing mogul and a second hardened dowel pin disposed between the escutcheon and the first driver pin bore and axially and laterally staggered relative to the first dowel pin.
