A lock and a cooperating key combination is disclosed. The lock comprises a stator and a rotor with a keyway. The key comprises a penetrating portion for insertion in the keyway. The penetrating portion includes at least one combination surface and at least one movable element that can be extended beyond at least one surface of the key, adding height to said at least one surface of the key and for cooperation with at least one first control element for controlling rotation of the rotor. At least one second control element for controlling the rotation of the rotor is provided in the lock opposite the first control element with the keyway in between, the second control element comprising an additional internal spring operated pin acting solely as a pusher pin. The second control element cooperates with an aperture located on the opposite surface of the key, behind the movable element when the key is inserted in the keyway.
