The invention relates to a method for producing a flat key whose key shaft is provided on at least one face with profiles that serve as main and/or supplementary guiding grooves and/or with certain features. One or both faces are provided with base profiles (6), and a first undercut (1) is produced in one or more of these base profiles (6) the direction axis of which is different from the direction axis of the corresponding base profile (6). At least one base profile (6) that has a first undercut (1) is provided with a second undercut (4) which extends from the first undercut (1) and whose direction axis is different from the direction axis of the first undercut (1) and equal or different from the direction axis of the base profile (6). |
