A lock assembly for a keyed knob includes an insert, a cylinder assembly and a retainer. The insert is inserted into the knob after the retainer is attached thereto. The insert is inserted from the rear of the knob and attached thereto. The cylinder assembly is then inserted into the front of the insert until the retainer engages the cylinder assembly to secure the cylinder assembly into the insert. The cylinder assembly is readily removed by pressing on a step portion of the retainer with a tool inserted through the rear of the knob.
