  • - tongs.
Use for making a new key directly to the castle itself. This method in the practice of emergency works is called the indentation. It is the most efficient, economical and provides both duplicate and lock opening. The method of indentation is suitable for locks of lever type, device, with pins and cylindrical locking devices.
Take a billet (blank) for a key corresponding to a specific locking device (as an example, consider the cylinder lock). Insert the blank into the lock cylinder, being careful not to exert too much effort. Now grab the head blanks tongs with soft sponges; sponges should be parallel to each other.
Inserted into the cylinder billet turn fully to the right without much effort; otherwise you can break or bend the workpiece. Several times push the workpiece up and down. It is necessary to obtain the ingot of the future key distinct prints.
Proceed to the next cycle. Carefully turn the workpiece to the left. Now remove it from the cylinder. After these actions you will see on the workpiece well enough visible traces from the pins.
Treat yourself with a file or needle file the appropriate sections places where there are traces of markings (print pins).
Repeat the process of marking as long as the cutouts formed by the processing of needle files, will not become the necessary size and depth. Those areas on the workpiece that do not have distinct traces of the markings must not be processed. Areas where the cylinder needs to be a circuit, make perfectly smooth.
During processing of the workpiece needle files remove in a single pass only a small amount of metal. Better then to make another pass than to prevent irreparable marriage work. Work to duplicate it will go a bit slower, but decreases the likelihood that the workpiece will be spoiled.
From time to time insert the blank into the lock cylinder and then pressed. Repeat the operation until then, until the key becomes is unlock the lock.
