Help with locks, latches and door hardware
This service is for practical problems such as a stiff lock, a latch that no longer catches, worn handles, loose escutcheons or a lock that needs replacing as part of improving a door. The first step is to understand whether the fault sits in the lock case, cylinder, keeps, hinges, frame alignment or surrounding door furniture. Treating only the visible symptom can leave the underlying problem unresolved. We therefore look at how the complete door closes and operates before setting out the work. Where access is urgent or there is an immediate security concern, explain that when enquiring so the team can confirm whether the request is within scope and what options are available.
Choosing a suitable replacement
Locks and cylinders are not interchangeable simply because they look similar. Door material, existing cut-outs, backset, fixing positions, handle set and the way the door meets the frame all influence what can be fitted neatly. Photographs of both sides of the door, the edge and the existing lock are useful when preparing the visit. If replacement parts are required, measurements and compatibility should be checked rather than guessed. The aim is a tidy fit with smooth operation, not a forced substitute that weakens the door or leaves exposed gaps.
A careful installation process
Before drilling or removing hardware, the operative checks the door movement and records the current arrangement. The replacement is positioned, secured and tested repeatedly with the door open and closed. Keeps may need measured adjustment if the door has moved with age or seasonal conditions. The finished lock should engage without excessive force and the handles or thumbturn should return properly. Keys, supplied components and any maintenance guidance are handed over at completion. Electrical access control, alarms and specialist high-security systems may require a dedicated security contractor and should be described accurately at quotation stage.

CAREFUL PROPERTY WORK
Doors often need more than a new lock
Doors often need more than a new lock
A lock can appear faulty when loose hinges, swelling, movement in the frame or damaged timber prevents alignment. Correcting those contributing issues can be more useful than repeatedly changing a latch. Related door repairs can be discussed as part of the same enquiry, while structural damage, fire-door certification questions and complex communal-entry systems need the relevant specialist input. Sharing clear photographs and noting whether the door is timber, uPVC, composite or metal helps establish the right next step.
Information that improves the first assessment
Include whether the problem affects entry, exit or only locking; whether the key turns; whether the handle moves; and when the fault began. Photographs taken square-on help show the handles, cylinder and door edge. If the door is part of a managed block, confirm who controls the specification and whether matching hardware is required. This detail separates a mechanical lock issue from movement in the door or frame and reduces the risk of arriving with an unsuitable part.
Looking after newly fitted hardware
Do not force a key or handle that becomes stiff. Keep the door and frame under observation, especially after seasonal weather changes, and follow the lock manufacturer's maintenance guidance rather than applying an unsuitable lubricant. Retain product and key information. If the door begins to drag, address the alignment before the extra load damages the latch or cylinder.

LOCKSMITH FAQ
Before You Book
Useful answers for planning the work.
Can you replace a lock without changing the whole door?
Often, yes. It depends on the condition of the door and frame and whether a compatible lock or cylinder is available. The existing cut-out and alignment must be assessed first.
Why does my latch work when the door is open but not when it is closed?
That usually points to alignment between the latch and keep, sometimes caused by hinge movement, seasonal swelling or frame movement. The door should be checked before parts are replaced.
Should I provide the replacement lock?
You can, but the dimensions and compatibility need to be correct. Send photographs and any product details before the appointment, or ask for the required specification to be confirmed.
Do you work on communal or electronic access systems?
Describe the system when enquiring. Electronic access control, alarm-linked hardware and managed communal entrances may need a specialist contractor or authorisation from the building manager.
What information helps with a locksmith enquiry?
Include the door material, the problem, whether access is currently possible, and clear photographs of both faces, the edge, frame and existing hardware.
