A lockout padlock for securing a switch of an industrial plant comprises a lock housing composed of plastic, a hoop, a lock cylinder that has a cylinder housing and a rotatable cylinder core, and a key, with the cylinder core being rotatable between a locked position in which the hoop is locked or lockable to the lock housing and an unlocked position. The lock cylinder has a plurality of tumblers, with each tumbler being movable between a respective release position and a respective blocking position. The plurality of tumblers comprise a plurality of pin tumblers that are spring-loaded in the direction of their respective blocking positions. The plurality of tumblers furthermore comprise a plurality of supplementary tumblers that are not spring-loaded and that are freely movably supported between their respective release positions and their respective blocking positions.

A tubular lock assembly has a tubular lock, a cover, and a disassembling unit. The tubular lock has an annular keyhole and a cover screw hole enclosed by the keyhole. The cover is detachably assembled with the tubular lock, and has a covering board segment, a screw rod segment, and a first fitting segment. The covering board segment covers the keyhole. The screw rod segment is detachably screwed in the cover screw hole of the tubular lock. The first fitting segment is formed on the covering board segment. The disassembling unit has a second fitting segment. The second fitting segment corresponds in shape and size with the first fitting segment of the cover, such that the second fitting segment is adapted to engage with the first fitting segment, and the disassembling unit is capable of rotating the cover.

A key that controls a lock with a cylindrical plug, the key having a shank the body of which has an external, rounded surface and forms a hollow, partially enclosed profile. The external rounded surface is shaped for turning the key in the lock cavity of the lock, while at least in the end part of the lateral section of the shank, an open cavity is created for inserting an arm of the validating lever of the lock. At least a part of the shank is U-shaped or V-shaped fitted with at least one open coding track and/or at least one coding channel with a shaped coding surface.
