	The 6000 uses six pin-tumbler pins and five sidebar [[Side pin\|~~finger~~ pins]]. To open the lock, all pin-tumblers must be aligned at the [[shear line]] and all ~~finger~~ pins must be properly aligned with the sidebar legs. Balanced pin stacks are used to resist attack from [[comb pick]]s as well as reduces wear on the springs. Driver pins come in four sizes and use a modified spool design which is combined with counter-milling in the plug chambers to provide high pick resistance. There are nine depths for pin-tumblers, allowing for 531,441 (9<sup>6</sup>) theoretical key [[differs]] for the pin-tumbler portion of the lock. The [[MACS]] for this lock is five depths, giving the 6000 around 160,000 real key differs. [[Master keying]] is available using traditional pin-tumbler master pins available in eight sizes.

The [[MACS]] for this lock is five depths, giving the 6000 around 160,000 real key differs. [[Master keying]] is available using traditional pin-tumbler master pins available in eight sizes.

	Unlike many other sidebar locks, the Twin 6000 ~~finger~~ pins are identical. Cuts are made on the sidebar directly and ~~finger~~ pins must be raised to match these positions. All ~~finger~~ pins use serrations above and below the true gate to provide manipulation resistance. Rekeying of the sidebar portion of the lock is only possibly when the sidebar is physically replaced or flipped upside-down. This interaction between ~~finger~~ pins and sidebar gates frustrates traditional [[decoding]] attacks that attempt to measure the range of movement of the ~~finger~~ pins. There are five depths available for ~~finger~~ pins, giving the Twin 3,125 theoretical sidebar differs (5<sup>5</sup>). There are 2,800 real sidebar differs, using 1400 sidebars that can be flipped in either orientation. Keys blanks are stamped with a three digit indirect sidebar bitting code and sometimes an additional two digit keyway code.		Unlike many other sidebar locks, the Twin 6000 side pins are identical.

	To provide resistance against [[destructive entry]], the 6000 uses hardened steel pins in the front of the plug and near the sidebar and third and fourth pin-stacks. In addition, driver pins are made of stainless steel to frustrate drilling of the pin stacks.
