摘要：
A turnable lock cylinder (10) operable with driver (15u) und tumbler (15l) pins when positioned by a key (16) at a shear line (18) in which shearable assembly pins (15a-e) are assembled in the cylinder (10) and thereafter sheared to form such driver (15u) and tumbler (15l) pins for operation thereon. Each assembly pin (15a-e) is selectively weakened at a plurality of locations (17a-h) which correspond with notched depth heights of the family of keys capable of insertion in the keyhole. Such weakening (17a-h) is controlled so that pin shearing can be accomplished by application of rotational or linear forces applied to any part of the cylinder (10) except the key (16).
