Abstract
A cylinder lock-key combination including a cylinder housing, a key and a plug which has a circular-cylindrical barrel surface and which is rotatable in an opening in the housing. The barrel surface of the housing includes a key recess whose width exceeds its depth, and a plurality of code pin channels are preferably disposed in several rows. Code pin tumblers present in the code pin channels co-act with one or more blocking elements, such as pins or side bars, disposed in channels intended to this end. The blocking elements block rotation of the plug when one side surface of an inserted key presents wrong code surfaces. There is provided in this way a compact lock construction, which also enables the use of many code pins.
