FAQ - About our nightlatch

Unlike traditional nightlatches that sit on the surface of the door, our lock is fully morticed into the door, providing enhanced security. Additionally, our deadbolt mechanism is much more secure than a latch. While a latch is a passive locking mechanism that can be bypassed in under 30 seconds, a deadbolt offers a much stronger barrier against forced entry.

Yes, the auto-deadbolt nightlatch has a snib button below the bolt that can be moved up to temporarily disable the automatic deadbolt, allowing easy access when you're coming in and out of the house.

Yes, all Finfort locks can be keyed alike. This means that two or more locks—whether on the same door or different doors—can be operated with a single key, providing added convenience and security. Additionally, the Auto-Deadbolt Nightlatch can be keyed to the Manual Deadbolt in our Dual and Triple Door Lock Sets, offering a seamless locking experience across multiple locks.

A door pull is a plate that can be fitted to either the internal or external side of the door. If you don't have an internal door handle, we recommend using one door pull. If you have a door knob on the external side, a door pull isn't necessary, but you may choose to add one for aesthetic purposes.

The main difference lies in the type of cylinder, which changes how the door is opened. The Auto-Deadbolt Nightlatch is opened with traditional keys, while the Smart Auto-Deadbolt Nightlatch offers the added convenience of smart technology, allowing you to control and monitor access remotely via your smartphone. Both products feature the same mechanical automatic deadbolting functionality. Additionally, the traditional cylinder in the Auto-Deadbolt Nightlatch can be swapped out for a smart cylinder at any time in the future.

Robert Jones

A truly excellent lock
We were looking for a deadbolt nightlatch for our bed and breakfast property as part of the refurbishment of our entrance. It not only had to be stylish, but also simple for guests to use - easy to close without difficulty. This led us to Finfort. We are absolutely delighted with the lock and it really ticks all the boxes. Using high quality materials it really looks the part. A far more elegant solution to more traditional nightlatches and enhances the door.

George Petrides

Contemporary Door Lock
As an architect I have been in the construction business for over 40 years and this lock is the only one that is appropriate for a contemporary door. Being fully morticed it avoids the unsightly interior box which most escape locks have. Beautifully engineered and easy to fit. Full support was available from the Finfort team.
