The method and mechanism of the present invention aims, via the rotation button 9 caulked on the spindle 6, at the blockage and immobilisation of the moving latch bolts of the lock which are the moving latch bolt 2 actuated by the knob 3 and the moving latch bolt 4 of the cylinder 5 actuated by the key. In this way, the lock may be forced even by its own key. Said lock mechanism is placed at the inner side of the door so that no access thereto is allowed. |
