The M3 sidebar differs from previous models because it has small grooves cut out where the slider arms fit into. Functionally, it is the same as other Medeco sidebars; pin tumblers are properly rotated by the correct key and the sidebar legs can interface with the gates on each pin-tumbler.

The M3 slider is a spring-biased component located under the sidebar. In its default state, the slider arms block the sidebar from retracting. A protrusion on the right side of the key pushes the slider into the correct position and allows the sidebar to retract. Sliders and M3 keys may be master keyed to allow a variety of protrusions to properly position the slider, but the final resting position of the slider is always the same.
