REKEYABLE LOCK CYLINDER WITH ENHANCED TORQUE RESISTANCE

摘要

A rekeyable lock cylinder with a cylinder body and a plug assembly. The lock cylinder includes a plurality of key followers and a corresponding plurality of racks disposed in the plug assembly. The lock cylinder includes means for blocking rotation of the plug assembly with respect to the cylinder body to prevent unlocking of the rekeyable lock cylinder with an unauthorized object. In some embodiments, the blocking means is configured such that torqueing the plug assembly with an unauthorized object applies force to the blocking means without translating such force to the plurality of racks. This type of arrangement enhances torque resistance of the lock cylinder against attempted forced entry.
