SUBSTANCE: lock system with double-sided keys, which have code rows on flat sides, and with response cylinders with pins. On flat sides of keys, near key tips, there is a concave groove provided, which interacts with a convex groove on the movable coupled part in cylinders. The coupled part is installed as capable of displacement in direction of the axis x of the keys. Such concave groove provides for the possibility to insert the key for full depth due to adjacency of the specified concave groove along the entire surface to the convex shape of the coupled part. The concave groove, starting from the key tip, in direction of the axis x of the key, at first has the first inclination (N1), and then the second inclination (N2) relative to the key axis. The second inclination is more than the first inclination. The concave groove has a section, which is rounded in a concave manner around the axis x. The coupled part by means of the key moves in the direction x into the locking or switching position jointly with a connecting part, which is installed as capable of motion with geometric closure into the locking or the switching element. The rotation of the specified locking or switching element takes place as the key inserted for the full depth is turned, and causes activation of the locking or switching function.
