Claim:
Lock device with a key ( 10 ) and with a lock cylinder ( 30 ), comprising a spatially fixed cylinder housing ( 31 ) with a plurality of platelet tumblers, wherein the platelet tumblers are radially shiftable relative to a cylinder axis ( 39 )during insertion of the key ( 10 ) into an axial key channel ( 38 ) of the cylinder core ( 32 ) in order to sort the platelet tumblers on a cross-section of the cylinder core ( 32 ), wherein the key ( 10 ) has an edge profile with several planar outer faces ( 12 , 13 ) running at an angle to each other, wherein a control track extends in a longitudinal direction ( 29 ) of the key on an outer face and exhibits a pair of sensing positions ( 18 , 19 ) for each of the platelet tumblers engaging the control track, wherein the sensing positions are disposed opposite to each other in a key cross-section ( 11 ), wherein for a coding the position of the sensing position pairs ( 18 , 19 ) of the control track in the successively following key sensing positions ( 14 . 1 to 14 . 5 , 50 . 1 to 15 . 5 ) varies in a direction ( 16 , 17 ) perpendicular to the key longitudinal direction ( 29 ), and wherein for an analogous counter coding the platelet tumblers are located parallel to the cross-section of the cylinder core ( 32 ) and engage a corresponding sensing position pair ( 18 , 19 ) of the control track when the key ( 10 ) is inserted, characterized in that at least two types ( 40 , 50 ) of platelet tumblers are disposed in the cylinder core ( 31 ), wherein the platelet tumblers can be shifted in two radial directions ( 41 , 51 ) different from each other, since the platelet tumblers of a first type ( 40 ) can be shifted ( 41 ) parallel to a first outer face ( 12 ) of the key ( 10 ) and the platelet tumblers of a second type ( 50 ) can be shifted ( 51 ) parallel to a neighboring second outer face ( 13 ), wherein a first control track ( 21 ) of the first type ( 40 ) of the platelet tumblers is positioned at the first outer face ( 12 ) of the key ( 10 ) and a second control track ( 22 ) of the second type ( 50 ) is positioned at the second outer face ( 13 ), wherein counter sensing positions ( 42 ) of the platelet tumblers of the first type ( 40 ) engage the first control track ( 21 ) and the counter sensing positions ( 52 ) of the second type ( 50 ) engage the second control track ( 22 ), wherein the key ( 10 ) has a multi-edge profile with several planar outer faces ( 12 , 13 ), each of the outer faces ( 12 , 13 ) having control tracks, and wherein the control tracks are formed either as a control groove ( 21 ) or as a control rib ( 22 ), and wherein the first control track and the second control track ( 21 , 22 ) mainly have a constant track breadth apart from an initial section ( 20 ) at the free end of the key.
