<p>The invention relates to a disc tumbler cylinder lock and a key for it. T he key according to the invention comprises a groove (6) that is transverse to the key shank (2). The groove comprises a bottom section (6A) and side se ctions (6B) that are transverse to the bottom section between the bottom sec tion and the outer surface (2A) of the key shank. The bottom section of the groove is the key's main driving surface used to transfer turning force to t he disc tumbler cylinder lock. This reduces wear on the O-surfaces of the ke y because the O-surfaces do not transfer the majority or any of the key turn ing force to the disc tumbler cylinder lock.</p> |
