A non-circular spring cage extends through the first aperture, and the spring cage includes a second aperture. A spring cage spindle at least partially extends through the second aperture, and the spring cage spindle extends from the spring cage and includes a third aperture. A key cylinder is received in the third aperture. A handle including a fourth aperture receives the key cylinder and the spring cage spindle, and a fastener is received by the handle. The fastener is configured to couple the handle to the spring cage spindle and inhibit movement of the handle with respect to the spring cage spindle.
