20090078012 | METHOD FOR REKEYING A REKEYABLE LOCK CYLINDER - This invention is to provide a method for rekeying a rekeyable lock cylinder. The first step of entire rekeying process is to insert a first user key into a keyhole of a sliding block of a plug assembly and turn the first user key to rotate the plug assembly, then a thrust is added to the first user key to move the sliding block of the plug assembly, thereby disengaging a plurality of upper locking pieces and a plurality of lower locking pieces within a plurality of lower pin sets. Next, after pulling out the first user key from the keyhole, a second user key is inserted into the keyhole of the sliding block and turned to restore the sliding block as to reengage the upper locking pieces and the lower locking pieces. Finally, the second user key is pulled out to complete the entire rekeying process. Accordingly, the present invention may provide advantages of widely lowering rekeying cost and enhancing convenience in use, because lock replacement may be completed as soon as rekeying another user key only without replacing lock cylinder. | 03-26-2009 |
