Cylindrical lock has body with axial opening in which with possibility of rotation rotary cylinder is placed, with long channel for flat key, and split stopper discs, those are placed between the body and the rotary cylinder in disc niches at the side of the key channel, at the side of the last one they have rods going into it. In the zone where the surfaces of split are placed, between the body and the rotary cylinder, splits are arranged as sections of circle with radius equal to the radius of rotary cylinder. The flat key for the cylindrical lock has long slot in zigzag-like shape, on the concave cylindrical surface of the flat side of the key. Such structure of cylindrical lock simplifies its design and complicates the structure of the key.
