What is a Night Latch?

Traditional night latches are often found on the exterior doors of period properties. When the door closes, the night latch automatically engages with a keep on the door frame to lock the door. 

From the outside, a key is used to unlock the door, and from the inside, it's operated with a turn lever or in some instances a snib button. A snib button engages a deadlock mechanism to provide additional overnight security - when the snib is engaged, the key cannot unlock the door from the outside.
