Abstract (en)

The invention provides a system for closing a cylinder insert, a key for the system and a blank key intended for making an target key or duplicates thereof. The system for closing a cylinder insert comprises a key 1 and a cylinder insert 2. A second end 32 of a locking element 3 and a guiding channel 14 which has the form of an undercut groove, form a matchingly shaped slideable connection. The parallel longitudinal lines that define the profile of the second end 32 of the locking element 3 are inclined at an angle β, different than 0° relative to the insertion direction of the key 1, and the parallel longitudinal lines that define the guiding channel profile 14 made in the shank 12 of the key 1 are inclined at an angle α, different than 0° relative to the insertion direction of the key 1, and the angles α and β are in the same plane and may have various values, and only in the case when α = β it is possible to insert the key 1 into the key channel 23 of the cylinder insert 2 to the full depth and to unlock the locking element 3.
