Guardian Lock Ltd

Custom Lock Design. Precision Engineered. British Built.

Based in Willenhall, the historic heart of UK lock manufacturing, Guardian Lock Ltd has been designing and producing high-quality locks and latches since 1981. As the last independent lock manufacturer in the Willenhall area, we are proud to continue the town’s long-standing legacy of British lockmaking.

We specialise in custom-engineered solutions – from a single bespoke lock to full-scale projects – tailored to meet unique customer requirements.

With the components sourced and manufactured in the UK, we maintain strict quality control and consistent supply. Our trusted brands – Imperial, Benton, and Worrall – now offer over 400 lock types, backed by in-house design expertise and 100% product inspection.

As a BSI registered manufacturer, we’re proud to support security professionals and leading brands with British-made locks that deliver performance and peace of mind.

Imperial Locks – where quality is quite literally locked in.
