Abstract

Motor vehicle lock with a ratchet, latch, actuation lever, internal actuation chain, external actuation chain and a control, the ratchet having an engagement position in which it holds the latch in the closed position, and a raised position in which the latch is released, the ratchet being movable from the engagement position into the raised position by the actuating lever, the control having different operating states and depending on the state, the ratchet is actuatable via the actuation lever by the internal actuation chain from an inside door handle and/or by the external actuation chain from an outside door handle or not at all. In the base state, the internal actuation chain and the external actuation chain are coupled to the actuation lever and the internal actuation chain and/or the external actuation chain can be decoupled from the actuation lever by the control depending on the operating state.
