The cylinder lock comprises a cylinder shell (19) and a key plug (20) rotationally mounted in the cylinder shell to provide a shear line between the cylinder shell and the key plug. A key slot (11) extends into the key plug (20) parallel to its rotational axis for receiving a key blade (1). At least one locking tumbler (23a-23e) includes an elongated body portion (23ab-23eb) guided in a complementary, transverse cavity (33a-33e) in the key plug (20). - A fence (29) blocks the locking tumbler and is shaped so that rotational positioning of the locking tumbler with a properly shaped key blade allows the fence to clear the shear line. The locking tumblers each also have a finger (23af-23ef), which projects transversely outwardly form the longitudinal axis of the elongated body portion, so as to pivot abut the longitudinal axis (B) of the elongated body portion during rotation of the latter. blade to effect rotational positioning of the elongated body portion of the locking tumbler.
