 There are six positions available for discs, at 18° increments between 0° and 90°.  The discs are numbered 1 – 6, with corresponding cuts on the key.  The 1-cut is the deepest cut and does not rotate the disc.  The 6-cut leaves the key uncut, and the #6 disc rotates the plug once the sidebar retracts.

 The ABUS Plus works by using angled bitting cuts on the key to rotate discs. The key is inserted and rotated 90°; the angled cuts on the key in rotate the discs in the lock. When all the discs are rotated to the correct position, the sidebar falls into the true gates and the plug can be rotated. Washers are placed between discs to ensure that the key rotates each disc individually.
 There are six positions available for discs, at 18° increments between 0° and 90°.  The discs are numbered 1 – 6, with corresponding cuts on the key.  The 1-cut is the deepest cut and does not rotate the disc.  The 6-cut leaves the key uncut, and the #6 disc rotates the plug once the sidebar retracts.
 False gates are included on the discs with the intention of increasing the difficulty of [[Lockpicking|lockpicking]] and decoding.
