SUBSTANCE: invention relates to locking system with cylindrical lock and flat key. Locking system with cylindrical lock comprises cylindrical core installed with possibility of rotation in housing and containing locking slot and core pins, which are made with possibility of movement into locking slot, note here that at least one pin of the core has a reading ledge at its end directed towards the locking slot and extending towards the locking slot. Locking system also comprises a flat key for locking a cylindrical lock, comprising at least one coded side surface extending along the longitudinal length of the flat key and having control points located along the longitudinal length. At least one milled recess is formed in at least one control point, configured to receive the reading protrusion when the flat key is inserted into the locking slot. Flat key has a recess to receive the protruding part of the core pin when the flat key is inserted into the locking slot. Locking system is designed so that when the flat key is pulled out of the locking slot, the core pin is lifted to a sufficient distance so that the projecting part can completely come out of the recess.
