Definitions

  • the invention relates to a blank, a security key and a locking system with security keys and associated cylinders and a method for producing the security key from a blank according to the preamble of the independent claims.

  • the second tumbler is non-rotationally symmetrical, but positively guided and segmented with different shapes of two outer and one inner segment, wherein the outer segments of the second tumbler correspond to two additional grooves at the coding point of the second kind in the key. With the coding of the second kind, an additional turnstile with respect to the shear line can be effected.
  • safe operation over a long period of use and insensitivity to wear should be achieved, and rational, cost-effective mass production should be possible.
  • the new design should also require no additional space on the key with multiple coding rows. It should be covered with only one type of blank a whole market area and unauthorized key copies by a locksmith should be prevented.
  • This new blank block code system for example, is based on the previous block code system and additionally has new features, properties and functions with which the stated objects are achieved, as is also shown and explained with the figures.

This significantly increases the security of the locking system and also prevents counterfeiting and unauthorized key copies.
