A non-deadlocking Yale type nightlatch lock is typically fitted to a wooden door. From the outside of the door you would use a Yale type key to open the lock by turning the key to retract the latch on internal Yale type lock body. However, if you are inside the door you can always open this lock using the finger turn mechanism to retract the latch, hence it is not deadlocking and insurance companies would not consider it to be a high security lock.
A deadlocking Yale type nightlatch lock is also typically fitted to a wooden door. From the outside of the door you would use a Yale type key to open the lock by turning the key to retract the latch on internal Yale type lock body. However, as the name suggests it can also be deadlocked using the key. Some models deadlock by turning the external key ant-clockwise a full turn and removing the key, which then locks the internal finger turn preventing the door from being opened from either side without the key. Other models have an additional keyhole on the internal lock body of the door that can be deadlocked in a similar way, preventing the door from being opened from either side without the key
