The locking-unlocking mechanism locks and unlocks the lockset in response to rotation of the key within the lock core. The throw member includes an outer perimeter edge, a blade extending toward the locking-unlocking mechanism, and a channel extending around the outer perimeter edge. The body also includes a pin that extends into the channel so that when a key is rotated in the lock core, the lock core and throw member rotate relative to the pin. This rotation causes the throw member to move from an inactive position disengaged from the locking-unlocking mechanism to an active position where the blade engages the locking-unlocking mechanism.
