 What Type of Door Lock Do You To Replace or Change?

The most common lock types usually found on residential/commercial properties are the below three types of door locks:

1.  Nightlatch (often referred to as a Yale type lock)

For this type of door lock, even though there are many different types of nightlatch, and different back sets / dimensions, the same principal in most cases applies.

  • Pull or ‘slam’ door shut (door is latch locked) and requires a key to open from outside
  • On the inside the latch part of the lock is retracted usually by operating a small lever or handle.
  • Used on front/back and other entrance doors

This type of lock is normally fitted into the door and is usually operated by a longer brass or silver flag type key with teeth on the end in a symmetrical pattern.

  • Ranges in security usually ranging between 2 lever and 5 lever British Standard.
  • This standard is preferred by insurance companies as it means the lock has been tested against popular types of attack for a certain period of time. Which should ensure your property or business is secure if attacked.

Mortice Sash Lock

If you have handles on your mortice style lock this lock type is referred to as a sash lock, the handles operate the latch on the lock which keeps the door shut when pushed or pulled closed)

Mortice Deadlock

A deadlock does not have a handle and is always operated by a key, opened from one of both sides by key.
