Then the pliers are placed horizontally or vertically on the lock cylinder and, if necessary, locked. An attempt is made to place the pliers as close as possible to the door leaf or to the ceiling of the lock. Then the handle of the pliers is jerked to the right and left or up and down.

In one embodiment, the area of the forend screw hole is reinforced by very hard or very elastic materials or material combinations.
