We always put the needs of our customers first, which is why we offer a same-day emergency locksmith callout service. Our van has been purpose built and we carry a range of locks and equipment suitable for securing homes and business premises in Sheffield and surrounding areas.



“Stephen turned up at the time we had arranged…fitted the new locks quickly and supplied the most secure locks that are available.”
“Stephen explained which locks were available for my door and the difference between them. He arrived when he said he would, fitted my new lock and is a very polite professional gentleman.”
