Door Locks

We can repair or fit new door locks from our high quality range of accredited locks.


Why Choose Us

Door locks, multi point mechanisms, levers, springs and ball bearings over time will wear and eventually malfunction or break. This is inevitable especially to a locking mechanism of a main entrance or exit door.

Typically, SheffLOCK have found that many people in the past have had door locks replaced unnecessarily when all that needed was to repair or replace certain parts of the external door lock.

SheffLOCK’s approach is to ensure we provide you with the most cost effective solution to the problem whilst enabling the door lock to once again provide a smooth operation along with maximum security.

Layered Protection

If your door is not locking smoothly we advise a quick test that can be undertaken by yourself and only takes a few seconds: At the said door that is not locking smoothly, open the door. Whilst open, lift the door handle up (this should engage the multi point locking mechanism at the side of the door).

Door Lock Alignment

It is important to correct alignment problems. SheffLOCK who will know exactly how to realign your door. Attempting to resolve the problem yourself without the required knowledge and experience can quickly make the situation a lot worse.

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.

Laminated double glazing

It is advised that large rear facing doors and large windows are fitted with laminated glass double glazed panels.

This helps keep the glass panels in one piece if they are struck hard to prevent the glass from shattering into small pieces. Although the glass panel will show signs of damage it will prevent anyone from entering your house. We started SheffLOCK as a burglary prevention company because we know that the majority of victims of burglary are receiving either completely wrong Burglary prevention advice, outdated information or simply not receiving any advice at all.
