The M4 uses five or six pin-tumblers that provide axial rotation to interface with a sidebar. It uses standard, [[Security_pins|mushroom]], and barrel drivers.

The M4 sidebar differs from previous models because it has small grooves cut out where the side pins fit into. Once side pins are properly lifted by the correct side bitting and shuttle pin on the key, and pin tumblers are properly rotated by the correct key, the sidebar legs can interface with the gates on each pin-tumbler.

The M4 side pins are spring-biased components located to the left of the sidebar. In their default state, the side pins block the sidebar from retracting. A movable element on the right side of the key lifts the single Lift Pin into the correct position. Side milling on the key moves the three Finger Pins into the correct position. There are three different Finger Pins, with true gates at different heights, and false gates.
