Locks: Your essential buying guide
Start with the door type, how often it is used and the level of security you need. A front door may suit a mortice or multi-point lock, while a shed or cupboard may need a simpler padlock or cam lock. Always check the lock matches the door material and any existing fittings.
Check the measurements of the current lock and the available space on the door, including the backset, cylinder size and fixing points where relevant. If you are replacing like for like, compare the old lock with the product details carefully so the new lock lines up properly.
A key lock is useful when you want straightforward access with a physical key, while a combination lock removes the need to carry one. The better choice depends on who needs access, how often the lock will be used and whether you need shared access for more than one person.
It helps to choose locks that work with your existing door furniture, cylinders, handles and security features. A well-matched setup can make everyday use easier and reduce compatibility problems, especially on external doors or gates.
Before buying, identify the current lock type, measure it carefully and note how it is fixed in place. It is also worth checking whether you need a keyed-alike option, extra keys or a particular finish to suit the door and surrounding hardware.
Choosing the right lock is about more than just security. The best option will suit the door, the way it is used and the level of access you need, while also fitting neatly with your existing fittings. Use the sections below to narrow down the right style before you buy.
Different spaces need different kinds of locks. A main entrance, internal door, cabinet, gate or storage area all call for different levels of protection and access.
Think about how often the lock will be opened and closed, who needs access and whether the lock will be exposed to weather or heavy use.
The most common buying mistake is choosing a lock that does not match the existing door or fitting. Measure carefully and compare the current lock type with the product details.
Look at the fixing method, size, handedness where relevant and any part that needs to line up with the door or frame. This is especially important when replacing a lock rather than fitting a new one.
Keyed locks are a practical choice when you want simple, familiar access. Combination locks can be useful where several people need entry without sharing keys.
For doors and gates, consider whether the lock needs to work alongside handles, latches or cylinders. The smoother the fit with the rest of the hardware, the easier it will be to use day to day.
If more than one person needs entry, consider whether the lock allows straightforward shared access. That might mean extra keys, a keyed-alike setup or a combination style.
For locations that are used frequently, ease of operation matters as much as security. A lock that is awkward to open can quickly become frustrating in regular use.
The finish of a lock can help it blend with the door and surrounding fittings. This is particularly useful for visible areas such as front doors, gates and furniture.
A neat match between the lock and the rest of the hardware gives a more consistent look while still keeping the focus on security and practical use.
