This specification describes a lock where a key sets a multiplicity of elements such as disks, levers or others. After setting the elements, the key and the key slot (through which the key enters the lock) is moved out of contact with the elements and is subsequently completely isolated from them. The fence or any other component that co-acts with the previously set elements to open the lock cannot be brought into contact with them until the above isolating action has been completed.
