A trim attachment and method comprises a door lever/knob which is assembled to a spindle housing of a lock assembly by sliding the door lever/knob over the spindle. A retaining mechanism within the door lever/knob automatically engages the spindle to couple the door lever/knob to the spindle when the door lever/knob is properly positioned on the spindle. The spindle and door lever/knob have mating exterior and interior ribs providing torque transfer between the spindle and door lever/knob. An aperture is provided in the door lever/knob to depress a portion of the retaining mechanism to release the retaining mechanism, allowing the door lever/knob to be removed. The improved knob/lever trim attachment and methods provide an easily assembled and manufactured, aesthetically pleasing, and easily replaceable assembly for a door lock assembly.
