<p>The invention relates to a flat key for cylinder locks, which has on the side faces control grooves and, if appropriate, further control elements, such as indentations on the key bit for pin tumblers, control faces on the key spine and longitudinal ribs and longitudinal grooves in the key insertion direction. The flat key according to the invention is characterised in that on at least one of the two side faces (3) there are at least three control grooves (9, 10, 11), in that at least one of the control grooves (10) is made deeper than the other control grooves (9, 11), and in that the two shallow control grooves (9, 10) extend approximately parallel to one another. …<??>Furthermore, the invention relates to a cylinder lock for flat keys, which is characterised in that, on at least one side of the key channel (34) and approximately parallel to this, there are at least one control element (30) with a control member (37) engaging into the shallow control groove (9, 11) of the flat key (3) and at least one control element (29) with a control member (35) engaging into the deep control groove (10) of the flat key, and in that there is at least one blocking element (26) which, in an appropriate position of the control elements (29, 30), can be brought into the release position for the rotation of the cylinder core (23) in relation to the cylinder housing (22). …<IMAGE>… </p> |
