The invention relates to a cylinder core (1) which can be mounted in a rotatable manner in a locking device, in particular of a storage compartment or of a glove compartment of a motor vehicle, and has a head region (6), which has a key channel (2) into which a key can be introduced, and a retaining region (7), which adjoins the head region (6) and is formed with a control means (8) which, when the cylinder core (1) is rotated about its axis of rotation (11), moves an arresting means, which is arranged in the locking device, for a closing and/or opening operation. The invention provides for the cylinder core (1) to have at least two material bodies (6, 7, 8), wherein a first material body (6, 7) is configured with the head region (6), which contains a first plastic, and a second material body (7, 8) is designed with the control means (8), which contains a second plastic, the second plastic having a higher strength than the first plastic.
