Method for preventing unauthorized unlocking of a code unit of a device of a lock variety

摘要

A method for unauthorized unlocking of code unit devices of a lock variety by manipulating coding elements is largely performed all over the world. This practice also relates to unauthorized detection of worksites of dividing dials having a digital mark up with numbers and symbols, by means of visual methods. The inventive method makes it possible to exclude a manipulation for obtaining signals perceptible for aural and touch reception which can be used for the unauthorized unlocking of code units by means of blocking an alternate access to code elements accompanied by blocking a riegel, and also by using the digital mark up having neither numbers no symbols which place the dividing dials in an operative position using signals perceptible for organ of touch only.
