Happy Customer

Chris came today explaining the workings of the handles and anti snap locks. He was very efficient and knowledgeable of his trade, fitted four handles and locks within an hour explaining the operating system as he continued.Being ex police we fell confident trusting his expertise, very happy with the handles and locks feeling much more secure in our home.

Jonathon Streets
Atempted break-in

After an attempted break-in via snapping my euro cylinder lock, ShefLOCK turned up within two hours (I'm based in east Doncaster) and fitted Ultion Locks and secured by design handles. Very thorough with their explanations and careful with installation including cleaning up after themselves.

Recent Articles

We have gained a vast amount of security knowledge with over 40 years of police experience. There is so much to talk about so we have put our experience on paper in bite size, easy to read pages.

Burglary Prevention Advice

We often speak to customers who were victims of a burglary over 20 years ago, who remember the details of such an incident, recalling what an awful experience it was and wanting to do all they can to prevent such an event occurring again.

The facts are that Burglary is and always will be a real concern for all of us. We started SheffLOCK as a burglary prevention company because we knew that the vast majority of victims of burglary and the public as a whole are receiving either completely wrong Burglary prevention advice, outdated information or simply not receiving any advice what so ever.
