ABSTRACT:
A removable core (15) for a lockset (10) has a core removal ring (35') which is provided with a gap therein which prevents the lock from being picked by turning the core removal ring with an elongate wire having a wedge-shaped end. One of the end edges of the core removal ring (35') defining the gap is positioned in substantial registration with a keyway (18) at an approximate 6 o'clock position. The other end edge of core removal ring (35') normally resides at an approximate 3 o'clock position.
