Passive leaf lock for mounting in or on a passive leaf of a two-leaf door, having a lock housing formed as a lock case or lock frame, in which a lock mechanism and an electric door opener device is mounted, wherein the lock mechanism comprises: • an upper locking rod connection device, to which an upper locking rod is connectable or is connected, and/or a lower locking rod connection device, to which a lower locking rod is connectable or is connected, and • an actuation connection device, to which an actuation device, which has a manual or motorised actuator, is connectable or is connected for actuating the lock mechanism, - wherein the electric door opener device comprises: • a door opener latch, which is moveably mounted in the lock housing in such a way that, in the closed position of the door, the door opener latch interacts with a lock latch or a bolt of an allocated active leaf lock, • an electric blocking device, which has an electric actuator, which is formed as an electric coil or an electromagnet, and a blocking member on the output side, which interacts with the door opener latch directly or via an interposed door opener gear, which is formed from a gear element or from a plurality of interacting gear elements, in such a way that the door opener latch is switchable into a blocking position and into a release position, • a mechanical unlocking means, which, in the closed position of the door, is actuatable via the actuation device and/or a separate unlocking handle, - wherein the door opener latch interacts with the electric blocking device and the mechanical unlocking means in such a way that the door opener latch is switchable from its blocking position into its release position on the one hand by electrically changing the energisation of the electric blocking device and on the other hand mechanically by actuating the mechanical unlocking means, characterised in that the mechanical unlocking means interacts with the electrically switchable actuator of the electric blocking device in such a way that, by actuation of the mechanical unlocking means, the electric actuator is displaced and the door opener latch is thus switched mechanically into the release position. • an upper locking rod connection device, to which an upper locking rod is connectable or is connected, and/or a lower locking rod connection device, to which a lower locking rod is connectable or is connected, and • an actuation connection device, to which an actuation device, which has a manual or motorised actuator, is connectable or is connected for actuating the lock mechanism, - wherein the electric door opener device comprises: • a door opener latch, which is moveably mounted in the lock housing in such a way that, in the closed position of the door, the door opener latch interacts with a lock latch or a bolt of an allocated active leaf lock, • an electric blocking device, which has an electric actuator, which is formed as an electric coil or an electromagnet, and a blocking member on the output side, which interacts with the door opener latch directly or via an interposed door opener gear, which is formed from a gear element or from a plurality of interacting gear elements, in such a way that the door opener latch is switchable into a blocking position and into a release position, • a mechanical unlocking means, which, in the closed position of the door, is actuatable via the actuation device and/or a separate unlocking handle, • a door opener latch, which is moveably mounted in the lock housing in such a way that, in the closed position of the door, the door opener latch interacts with a lock latch or a bolt of an allocated active leaf lock, • an electric blocking device, which has an electric actuator, which is formed as an electric coil or an electromagnet, and a blocking member on the output side, which interacts with the door opener latch directly or via an interposed door opener gear, which is formed from a gear element or from a plurality of interacting gear elements, in such a way that the door opener latch is switchable into a blocking position and into a release position, • a mechanical unlocking means, which, in the closed position of the door, is actuatable via the actuation device and/or a separate unlocking handle, - wherein the door opener latch interacts with the electric blocking device and the mechanical unlocking means in such a way that the door opener latch is switchable from its blocking position into its release position on the one hand by electrically changing the energisation of the electric blocking device and on the other hand mechanically by actuating the mechanical unlocking means,
