Claim:
A method for re-keying a lockset comprising: providing a lockset having a look cylinder body, a first axis, and a plug assembly, the plug assembly including a guide bar and a plurality of first pin members and a plurality of second pin members, each of the first pin members being coupled to an associated one of the second pin members to inhibit relative movement therebetween along the first axis; inserting a first key with a first key profile to the plug assembly to align the second pin members in a predetermined orientation; rotating the plug assembly relative to the lock cylinder body to maintain the second pin members in the predetermined orientation; moving the guide bar parallel to the first axis; moving the guide bar transverse to the first axis to uncouple the first pin members from the second pin members to permit relative movement therebetween along the first axis; removing the first key from the plug assembly; inserting a second key with a second key profile to the plug assembly to reposition at least one of the first pin members relative to a respective one of the second pin members along the first axis, the second key profile being different than the first key profile; re-coupling each of the first pin members to the associated one of the second pin members.
