Latch bolt is automatically deadlocked when door is closed. Double throw dead bolt is locked by key only. Unlocking of both latch bolt and dead bolt is by either key or electronically. Alternatively, the lock can be set up so that the deadbolt is not opened electronically by removing a small lever inside the lock (clearly explained in the lock instructions). The lock forend and strike plate are a satin brass finish. The lock is supplied without euro profile cylinder - order suitable length double or key and turn cylinder separately.
