Nightlatches Explained – Choosing the Right Front Door Lock

A nightlatch is one of the most popular front door locks used throughout the UK, offering convenience, security and ease of use for residential properties. Commonly referred to as a "Yale lock", a nightlatch automatically secures the door when it closes, making it an excellent choice for homeowners, landlords and property managers.

At Garrison Locks, we stock a wide range of nightlatches suitable for timber entrance doors, including traditional, deadlocking, non deadlocking nightlatches and British Standard models from leading manufacturers.

What is a Nightlatch?

A nightlatch is a surface-mounted lock fitted to the inside face of a door. It is operated using a key from the outside and a knob or lever from the inside.

Unlike a mortice lock, which is installed inside the door, a nightlatch is fixed to the door surface, making installation straightforward and ideal for replacing an existing lock.

Most nightlatches automatically engage when the door closes, providing everyday security without the need to manually lock the door.

Types of Nightlatches

Traditional Nightlatches

A traditional nightlatch automatically locks when the door closes and can usually be held open using the internal snib, making it convenient when regular access is required.

These are ideal for:

• Houses
• Flats
• Internal entrance doors
• Utility rooms

Deadlocking Nightlatches

Deadlocking nightlatches offer increased protection by preventing the latch from being forced back using common methods such as carding or other forced-entry techniques.

Many models include an internal deadlocking function, providing greater resistance against unauthorised entry.

British Standard Nightlatches

For higher levels of security, British Standard nightlatches are independently tested to meet recognised security standards and are often recommended by insurers for external timber doors. These models offer enhanced resistance against drilling, picking and forced attack.

Why Choose a Nightlatch?

Nightlatches remain one of the most popular front door locks because they provide:

• Automatic locking when the door closes
• Quick and convenient operation
• Reliable everyday security
• Straightforward installation
• Ideal replacement for existing locks
• A range of security levels to suit different properties

Many homeowners choose to install a mortice deadlock alongside a nightlatch to provide an additional layer of front door security.

Choosing the Right Nightlatch

Before purchasing a nightlatch, consider:

• Door thickness
• Backset size
• Security rating
• Left or right-hand operation (where applicable)
• Internal escape requirements
• Insurance requirements

Choosing the correct model ensures smooth operation and the right level of protection for your property.

Finishes to Match Your Door Furniture

Nightlatches are available in a variety of finishes to complement your existing door furniture, including:
