What type of lock do i have on my door?

The two most common locks types you will find in your door are the Mortice lock shown in the pictures directly to the right and the cylinder style (Rim) lock and key in the picture below. The shaft of the key of the Mortice lock is usually long with a protruding end at a right angle to the shaft.  The profile of the cylinder lock or Rim Cylinder is shorter and grooved on the flat edge.


Wooden doors you will find that a night latch has been installed so you will have a Rim Cylinder (small Yale type key) Also installed may be a Mortice Sash/Deadlock this will have a much larger type key as above.

Can my lock be repaired?

In most cases a repair is not a suitable option. Think about your security and insurance. Will you still be covered? Get in touch or check your insurance details.

Are my locks suitable for home insurance?

Without an inspection of both front and back locks and looking at your policy I cannot tell you for sure. However, we do offer a security check of your home at minimal cost. If you then decide to change your locks you will not be charged for the call out.  Most cases the insurance company will need you to install (wood doors) B/S 3621 approved mortice lock.
