FROM £35


Cylinder locks, also known as barrel-style locks or anti-snap locks, have an internal mechanism that works with a set of pins that align to the correct position when operated with a key.

They provide great security to your doors and home, but every now and then, they do need replacing or upgrading. Some of the most common reasons are:

Faulty or damaged locks – the lock has become unreliable or difficult to operate, mainly due to wear or damage
Moved into a new home or business address – have the peace of mind knowing you are the only ones with keys to your new doors
• Keyless entry – upgrade your lock to a Smart Lock
Keyed Alike – change your locks so that multiple locks can be opened with one key
Upgrade locks to BS3621 – insurance companies often require locks to conform to British Standard 3621
Lost keys
• Burglary damage
