The best locks for your doors

keys in door

The security of your home is your number one priority, after all you’re not just protecting the possessions you’ve worked hard for, but the people who live in it. That’s why it makes sense to install CCTV systems and burglar alarms you can rely on, but it’s just as important to have strong doors with high quality locks. Having a good door with a good lock can act as an immediate target to opportune thieves who are looking for an easy haul, but with lots of locks and door security devices to choose from, which is right for you?

A good lock needs a good door

A lock is only as secure as the door it’s attached to, as if the door itself isn’t strong enough, then professional criminals will easily be able to open it using brute strength and their housebreaking tools, without having to turn their attention to the lock. For that reason, your doors should always be tough and in good condition, and that applies to external and internal doors. Timber internal doors not only look great, but they are also very strong and long lasting, and can’t easily be forced to yield. Whether you like traditional four panelled doors, or contemporary styled doors painted white, criminals won’t like them if you pair them with a suitable lock.

Mortice locks

Mortice locks are traditionally associated with exterior and interior timber doors and windows, and they can be either sash locks or deadlocks. If you opt for a mortice sash lock, look for one that has five levers rather than three, as that makes it stronger and more secure.


Latches are used on both interior and exterior doors to keep them closed, and a nightlatch works by locking the door as soon as it’s slammed shut. It can be opened with the aid of a key and provides an added level of security, but most people would combine it by adding it to a door that already has a mortice lock rather than using it on its own.

Rim cylinder

A rim cylinder lock is another kind of lock that is used alongside a nightlatch, and together they can make your timber doors even more secure. The cylinder itself fits inside a brass barrel which is then inserted into a purpose made hole in the door. It’s easy for a joiner or locksmith to create this hole on a wooden door, which is another reason why timber doors can often be much more secure than PVCu alternatives.
