Why Choose Us

key safes are one of our front line products to help remove the threat of burglars tampering with windows that have one lock levers.

Modern casement windows have multipoint locks similar to new doors.

Fitting two key safes is recommended so the window cannot be levered from a corner. This gives your windows the same protection as new multipoint lock windows.

Layered Protection

The unfortunate reality is that inadequate locks and handles, fitted as standard to the majority of windows installed everyday, are sadly unaware of how vulnerable to burglary they are.

Clean Design

key safes come in a variety of colours including white, brown and gold to give your windows that professional clean look. Fitting screws are hidden away under the protection of the metal window lock.

New Features

The humble key safe has been transformed over the years to provide a simple way of locking your window. The new easy cam feature makes it quick and easy to get access in case you need to open the window quickly.

key safe Fitting

Every window presents different obstacles to overcome to make sure the key safe secures your window and at the same time, easily accessible so you can remove the locking cam.

Why are they not standard?

It has been found that single locking windows have been found to be vulnerable to levering so modern windows now have multi-locking pin along the window edge. key safes make older windows secure to the same level.

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.

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of victims of burglary and the public as a whole are receiving either completely wrong Burglary prevention advice, outdated information or simply not receiving any advice what so ever.
