Window Will Not Lock, or the Handle Has Broken?
HD Locksmiths Bournemouth repairs and replaces window locks, handles and mechanisms across Bournemouth, on uPVC, aluminium and timber windows. A window that will not lock is nearly always a hardware fault and not a glass fault, so the fix is a repair rather than a new window.
Typical complaints: a handle that is loose or spins, a handle that turns but locks nothing, and a window stuck shut. There is no call-out charge.
Lock Fault or Window Fault?
The quickest way to narrow down a window lock fault costs nothing. If the window opens normally and it is safe, open it fully and work the handle gently with the sash standing free; stop if the handle or key requires force.
If it locks fine with the sash open
The mechanism is probably working, and the issue may be how the locking points meet the keeps. A sash dropped on worn hinges is a common reason, and the keeps may need adjustment. Inspection confirms whether realignment is the answer or another part contributes.
If it fails when the sash is open too
The fault is more likely inside the hardware, with the handle, spindle, gearbox or locking strip each a candidate. Inspection identifies the affected part, and if it needs replacing we discuss compatible options before work starts.
Never force a stiff handle or key, and stop using the window if a part loosens, bends or needs excessive effort.
Why the check helps: a window locking system has several connected parts, and a problem in one can affect the handle, the sash or the locking points. The result you obtain helps establish whether an adjustment, replacement of an individual part or a compatible replacement mechanism is needed. A window that will not lock or close can leave a home in Bournemouth less secure, but it may not need replacing, because the fault could involve the handle, the mechanism or how the window sits in the frame.
When calling, let us know if the window has become stuck, is hard to close or has stopped locking securely. We use that information to help us assess the problem and organise an inspection.

Parts That Fail on a uPVC Window
When a window stops locking, the hardware is the first place to look. On a uPVC window that hardware comes down to four groups of parts, each with its own way of failing.
The handle and the spindle
The handle is simply the part you turn, joined by a square metal spindle to the mechanism in the sash. If fixings work loose, the spindle wears or the handle is damaged inside, the lock may not operate. Where the fault stops there, that component may be the only replacement needed.
The gearboxes
Sitting behind the handle, the gearbox carries the handle's movement to the locking mechanism. When faulty, it makes the handle stiff, lets it spin without engaging or stops the locking points moving. It is replaced separately or with the strip, as the design dictates, matching the existing dimensions and mechanism.
The espagnolette strip
The espagnolette ("espag") is a metal strip on the edge of the opening sash, carrying the locking points that engage the frame; a related shootbolt system is found on some windows. If it becomes bent, worn or jammed, it may prevent the window from opening or locking. Compatibility with the window’s dimensions and existing hardware must be ensured when choosing the replacement.
Hinges and keeps
Friction hinges support the sash and affect how it sits in the frame; keeps are the metal components receiving the locking points. Worn hinges or wrongly positioned keeps stop it closing and locking smoothly. Problems with the wider window may require a window specialist.
Next, tell us whether it is stuck, difficult to close or unable to lock, what the handle or key does, and the open-sash result if completed safely. From your description, we price the work on the call; it stands unless the job differs on site, with changes explained before we start. The agreed adjustment, repair or replacement follows, tested with you where practical. Window-lock work suits a planned appointment; where an accessible window cannot be secured, call about current urgent availability.

What Is the Window Doing?
Window lock faults show themselves in a handful of ways, and naming yours helps us understand the problem before anyone visits. Behind them sit three broad causes: faulty handles, failed mechanisms and windows no longer aligned with the frame, and each still needs inspecting before the work is confirmed.
When the handle is loose, wobbly or spins
Loose fixings, a worn spindle or internal handle damage are the usual causes. Swapping the handle can be enough to restore normal operation, although the locking mechanism should be checked before that is confirmed.
The handle turns but the window will not lock
The spindle, gearbox or locking strip may have a fault, so the handle moves but the locking points stay put. The window looks closed while remaining unsecured; avoid leaving an accessible window like this.
A window stuck shut that will not open
A jammed gearbox, handle or locking strip can stop the sash from opening. Avoid forcing the handle or pulling at the frame, which places more strain on the hardware. It needs inspecting to find the jam and a safe opening method.
When the window will not close properly
Look to a dropped or misaligned sash, worn hinges or keeps in the wrong place. Adjustment may put it right without replacing the lock. Keep forcing it closed and the locking hardware takes extra strain.
When the key will not turn in the handle
The key may be worn or damaged, or the handle's small internal lock may have failed. Test an undamaged spare if you have one, without forcing either key. Some windows accept a complete new locking handle with new keys.

Lost Your Window Key?
You may not need a locksmith to replace a lost window key. Many locking window handles use common, identifiable key patterns rather than a key unique to your window, so if the handle and pattern can be identified, a replacement key may well be available. A code stamped on a surviving key or on the handle can help pin down the right one, though availability depends on the handle, the key pattern and the supplier. Resist trying a similar-looking key: it may not match the internal pattern and could damage the handle.
Replacing the whole locking handle makes more sense when the correct key cannot be sourced, when the existing lock is damaged or unreliable, when the handle itself has stopped working, or when you want keys you can no longer account for to stop operating the window. A compatible replacement handle can be supplied with matching new keys, so the old ones simply stop working.
No New Window Is Needed
Glazing firms replace windows. Locksmiths repair the hardware that locks them. It is worth knowing the difference, because a window that will not lock, open or close properly may not need replacing at all; the correct service depends on whether the fault lies in the locking hardware or in the window's wider structure.
Usually a hardware job
- A handle that is loose, broken or spinning
- A key or handle that no longer operates the locking points
- A stiff or jammed gearbox or locking mechanism
- Locking points that fail to engage the frame
- A minor alignment problem affecting the lock
These may be fixed with an adjustment, a repair or a compatible replacement component.
Usually another trade
- Damaged glass or a damaged sealed unit
- A frame that is cracked or badly distorted
- Structural damage to the opening sash
- Misalignment severe enough to fall outside the locksmith's scope
- A problem that repairing the lock would not resolve
A glazier normally handles glass and sealed units, and a window specialist may be required where the frame or sash needs structural work. If you are unsure, we assess the fault and explain whether it is within our window-lock service; when another trade is more suitable, we tell you before any work is agreed.

Locksmith pricing
How Much Does a Window Lock Repair Cost?
Window lock repairs are priced by the fault, not by a flat rate. A reliable price depends on the problem, the affected part and the work required, since a loose handle, an alignment problem and a failed locking mechanism can each involve different parts and labour. Usually a handle swap costs least, a gearbox more and a full espagnolette replacement most, and all three are normally far cheaper than a new window.
| Factor | Why it matters |
|---|---|
| Type of fault | An alignment adjustment is different work from repairing a jammed mechanism |
| Component | Handle, gearbox or wider locking mechanism can change the price |
| Compatible parts | Older or discontinued hardware may take longer to identify or need a suitable alternative |
| Number of windows | Several windows can be considered together |
Window not locking properly? Describe how the window is behaving, let us know the number of windows affected and provide clear photographs if asked. The open-sash check shows whether an adjustment may solve the problem, which helps. We price the repair on the call from what you describe; that figure holds unless the job differs on site, and we explain any change and agree the work before starting. We work through lock and alignment problems on uPVC, aluminium and timber windows and explain the repair and replacement options. No call-out charge, at any hour. In short, you pay for the work carried out, any parts needed, and VAT; rates outside Monday to Friday, 7am to 6pm, are higher, but the call-out itself is never charged.

Home Insurance and Your Window Locks
Insurance is a good reason not to leave a faulty window lock for later. Some home-insurance policies specify key-operated locks or other security measures for accessible windows, commonly ground-floor windows and those reachable from a flat roof, balcony or extension. Consult your policy wording or seek confirmation from your insurer about which requirements apply to you, as these can differ. Tell us if the window will not lock, the key has stopped turning or the handle no longer operates the mechanism, and share the written requirement when you contact us. The work may be an adjustment, a repair or a compatible replacement component, depending on the fault. We will assess the window and explain whether a suitable key-operated locking handle or window lock can be fitted, though only your insurer can confirm that the installation meets your policy.

Frequently Asked Questions
Does a broken window lock mean I need a new window?
In most cases, no. What normally fails is the hardware: the handle, the spindle or the locking mechanism behind it. If the glass, frame and sealed unit are in good order, replacing or adjusting those parts may be all that is needed, at well below the cost of a new window. Inspection shows which applies, including the rarer cases where another window specialist should take over.
How do I know if it is the lock or the window itself?
Operate the lock with the window standing open. If the handle moves freely, the hardware is probably working and the issue is how the sash meets the frame, such as worn hinges or keeps needing adjustment. If the handle is still loose, stiff or doing nothing, the fault lies in the hardware. Do the check only if the window opens normally and safely.
My window handle is loose and spins. Is that expensive to fix?
Usually it is not. The likely causes are a worn spindle, fixings that have worked loose or damage inside the handle, and a new handle is one of the more affordable fixes on a window, sometimes the only one needed. We confirm by checking the locking mechanism as well, and the call-out itself is never charged.
Can I get a replacement key for my window lock?
Usually you can try. Availability of a compatible replacement key for your window varies, but identification may be helped by a key code, the handle model or a manufacturer's marking. Avoid forcing a similar-looking key, which could damage the handle. Replacing the locking handle may be the more appropriate option when you want missing keys to stop working, when the lock has suffered damage or when a suitable key is unavailable.
Do my window locks affect my home insurance?
They can do. Some policies specify key-operated locks on windows that are accessible, such as ground-floor windows or those reachable from a flat roof, balcony or extension. Insurers and properties differ, so read your policy wording or ask your insurer to confirm. A broken window lock is therefore worth fixing promptly for insurance as well as security reasons.
My window is stuck shut. Can you open it without breaking anything?
Normally, yes. A sash stuck in the locked position usually has a jammed mechanism or a worn espagnolette strip, and it can generally be freed without harming the window. An inspection confirms the jam and how to open it safely. Forcing the handle adds strain and can crack the frame, so call us before you try.
Can you do several windows in one visit?
Yes, and it is usually the sensible way to do it. Windows of the same age tend to fail around the same time, so if one handle or mechanism has gone, others are often close behind. Tell us how many windows need attention when you call, so the work can be considered together, and we can tell you which genuinely need work now and which are fine.
Should I call a locksmith or a glazier?
Problems with the window handle, spindle, lock, multipoint locking mechanism or the way the sash engages the frame are reasons to call a locksmith. A glazier is generally better for broken glass, a damaged sealed unit or misting trapped between the panes, and structural problems with the sash or frame may need a window specialist. If we find the real problem is the frame or glazing, we will tell you rather than fit hardware that will not solve it.
