A lock set with a quick changeability has a plug (20), a cylinder (30), a seat (70), a ring (60) and a sliding cover (80). The plug (20) is mounted in the cylinder (30) and has multiple first holes (23) in which multiple lower pins (40) are inserted. The cylinder (30) has a chamber (31) into which the plug (20) is inserted and a lug (301). Multiple second holes (33) are defined in the lug (301) and multiple upper pins (50) and springs (51) are inserted into the second holes (33). Multiple openings (32) are defined in a lower inner wall of the cylinder. The sliding cover (80) abuts the lower inner wall of the chamber (31) and ha s multiple orifices (81) in rows defined therein. Hence, it is easy for a user to change a corresponding key (10).
