Structure of key contains on the blank of key (1) at least one flat part (11), at least one part of a coded access and the cylinder lock (5) to lock off. To completion, to the part of the coded access, the key on flat part (11) further comprises at least one groove (12) with a hole in the flat part (11), a flexible element (2) fitted in the groove (12) and pressure element (3) determined into the groove (12) and moved by the flexible element (2). The pressure element (3) includes a front pressure edge (31) overlapping the hole. When is the pressure element (3) moved by flexible element (2), the front pressure edge (31) provides the pressure force outwards from the hole or the front pressure edge (31) is compressed so that it moves inward. The cylinder lock (5) has a lock pin module (7), fitted to the position corresponding to the front pressure edge (31), to move the pressure element (3) or that it was moving by element (3), in order to create safeguard mechanism so as to achieve thief-resistant effect. |
