Lock Not Working Properly? We Repair It Rather Than Replace It
L.M.N Locksmiths Lancing repairs faulty door locks, handles and door alignment across Lancing, and says so plainly when a repair is all that is needed. If the door will not secure, ring now; if it still locks, book a weekday visit.
The faults we are called to most: a key that is stiff or will not turn, a handle that has gone floppy or will not lift, a door that has dropped or sticks, and a lock that spins without catching. There is no call-out charge. If a repair does not make sense for your lock, lock replacement is the alternative.
Is It the Lock, or Is It the Door?
Two very different faults can feel the same from the handle side. Open the door all the way, operate the key and handle with the door standing free, and the result will usually tell you which one you have.
If the lock works fine with the door open
That points to the door rather than the lock. When the key turns and the handle moves more freely in this position, the locking points have probably stopped meeting the frame correctly. Hinges that have moved, or a keep or strike plate sitting out of place, are the usual causes. The keeps and strike plates are there to receive the latch, bolt or locking points when the door shuts, so even a small drop puts them out of line. A serviceable lock may need nothing more than adjustment.
If the lock still fails with the door open
That points inside the lock. The cylinder, latch, gearbox or another internal component may have a fault.
| Symptom with the door open | Probable cause |
|---|---|
| Works more easily | Door alignment, hinges or keep position |
| Still fails | Lock component or internal mechanism |
What the repair looks like depends on the lock. A Euro cylinder, common on uPVC, composite and aluminium doors, can often be replaced on its own, even though a stiff key in one could also be alignment or another part. A mortice lock lives inside the edge of a timber door (and similar cases appear on many internal doors), with the latch, bolt, case or alignment all possible culprits. A nightlatch is surface-mounted on timber and can fail at the rim cylinder, latch, body or door position; some of its parts are replaceable individually. A multipoint system secures uPVC and composite doors at several points, so the affected part must be identified first. And a loose handle, worn spindle or faulty latch can often be repaired or replaced without a new lock.
Resist the urge to force anything: it puts more load on the key, cylinder and mechanism. Stop if the key bends, a part is loose or the door is damaged.
If you cannot tell what has failed, ask us to inspect the lock and door, or go to.
Common Door and Lock Faults We Repair
Some lock problems announce themselves loudly, others creep up over weeks. In each of the cases below an inspection is the step that shows whether adjustment, repair or a replacement component is needed.
A floppy handle, or a handle that will not lift
A handle that hangs loose often has worn fittings or a damaged spindle; one that refuses to lift on a multipoint door may have a mechanism fault. We work out which and repair it.
A stiff key, or a key that will not turn
Door alignment, a worn cylinder, an internal mechanism fault, pressure on the locking points and a worn key can all make a key stiff. Do not force it: stop, and get it checked.
A lock that turns freely without locking
The key rotates freely and the bolt stays put. The door may look secure and not be, so this should be dealt with rather than lived with.
A door that has dropped, sticks or will not close
As hinges wear or the door moves, the latch and locking points stop meeting the keeps. Adjustment of the door, hinges or keeps usually brings it back.
A lock that is broken or has been forced
We inspect the lock, door and frame and repair or replace as needed, but after a break-in none of this starts until the police give permission.

Why Forcing a Sticking Lock Costs You More
Here is something the trade knows well and rarely tells customers: forcing a sticking lock is how a small repair becomes a large one. A key that will not turn easily or a handle that resists is warning you, and adding pressure strains the key, cylinder, handle and internal mechanism further.
Left to carry on, the gearbox in a multipoint mechanism can finally break, frequently leaving the door locked shut. The price climbs in steps: alignment adjustment is normally least expensive, a replacement mechanism is more, and opening a jammed door before replacing the mechanism is the most costly route of all. The original cause may have been nothing worse than alignment or a loose fitting, and continued force only made it harder to repair.
A key starting to bend, a loose handle or an inability to secure the door are reasons to stop operating the lock. Have the lock inspected to establish the cause before additional work becomes necessary.
When repair or adjustment usually works: the door is out of line but the lock is serviceable; the handle, spindle or latch has developed a repairable fault; alignment or a loose fitting is causing the stiffness; a single replaceable component has failed while the rest of the locking system is fine; or the keeps or strike plate need adjusting. Normal operation may return after that component is repaired or adjusted, without replacing the entire lock.
When replacement usually makes more sense: the lock is damaged beyond secure repair; compatible parts cannot be found; forced entry has made it unsuitable; lost or stolen keys should no longer open it; it no longer meets your security requirements; or your insurer has confirmed that a different lock type or standard is required.
Choosing a suitable solution requires consideration of both the fault and the lock’s condition. Read our lock repair vs replacement guide.

Alignment, Handle and Door Repairs
Many of the "lock repairs" we are asked about in Lancing turn out to be door repairs. Alignment, worn fittings and keeps that are out of position all affect how a lock works, and once a door stops sitting correctly in its frame, it presses on the locking system.
Signs to look for include a key that is difficult to turn with the door shut, a handle that is getting harder to lift, a door that has to be pushed or pulled before it will lock, and a latch or locking points that no longer engage smoothly. Remember that a door which closes but does not lock cleanly is a security weakness, not merely a nuisance.
What we do about it: - Adjust flag hinges on uPVC doors, raising, lowering or shifting them laterally, which may restore the door's position and reduce strain on the lock. - Replace hinges that have worn. - Reposition keeps and strike plates. They receive the latch, bolt or locking points when the door shuts, and if they no longer line up with the lock, moving a suitable one can restore engagement while the lock remains serviceable. - Refit or replace handles and spindles, since a loose or awkward handle may involve worn fittings, a damaged spindle or the connection to the mechanism. - Correct doors that have dropped or warped, using toe and heeling where needed: in plain terms, repacking the door within the frame so it sits level again.
Normal use may be restored by addressing the specific fault, without needing an entirely new locking system. Before anyone replaces your lock, arrange a check if opening the door alters its operation.

What Affects the Cost of Lock Repair
We do not publish a single repair price, because a quick keep adjustment and a replacement mechanism are very different jobs. What we do promise is a price on the call, worked out from your description, and no call-out charge. The figure depends on:
- Which component has failed.
- Whether the fix is an adjustment, which is normally the least expensive outcome, or a part replacement.
- Your door type.
- The time of day.
Charges: You pay for the work carried out, any parts needed, and VAT. After hours: Rates outside Monday to Friday, 7am to 6pm, are higher, but the call-out itself is never charged.

Do You Actually Need to Repair or Replace?
Some lock problems are an emergency; most are not. Blocked access or an insecure property makes the job urgent, but after a break-in we must wait for police permission before working at the entry point. That covers a door that cannot be locked, a lock or entrance damaged in an attempted break-in, a broken key that stops you entering or securing the property, a door stuck open, a door locked shut when you need access, and being locked out by a lock fault.
Everything else can usually be booked for a convenient time: a stiff key that still works, a handle that is loose while the door stays secure, a door that sticks but still locks, a lock that is getting difficult but still secures, or a door that needs alignment to lock smoothly. Arrange an inspection before it gets worse and the door can no longer be secured.
Whether we then repair or replace depends on the fault. Alignment problems, worn latches, loose handles, stiff cylinders and a lone failed part on a sound door usually call for repair. An obsolete lock with no parts, a forced door, keys that are unaccounted for or an insurer requesting a specific standard usually call for replacement. Adjusting is the job when adjusting is all a lock needs, and a good locksmith will not sell you more.
When you call, explain how your lock and door are behaving if anything here is unclear.
What affects the cost?
Service required, time of attendance, lock and door type, labour and parts.

Frequently Asked Questions
How do I know if it is the lock or the door?
The open-door test settles it. With the door fully open, operate the lock. Works easily? Then the lock is fine, and the door has dropped or the keeps have moved out of line with the locking points. Still stiff or not engaging? Then the fault lies within the lock itself. Most of the time, that result tells us what kind of repair is needed before anyone visits.
Can a door lock be repaired, or does it always need replacing?
It does not always need replacing. Many common faults, including loose handles, stiff cylinders, worn latches and doors out of alignment, are usually repairable. A replacement is more sensible when the lock is obsolete and its parts are not made any more, when the door has been forced, or when your insurer has asked for a specific standard.
My key is stiff. Should I use WD40?
Not as a lubricant. WD40 is a cleaner and water displacer rather than a lasting lubricant, and over time it can draw dirt into the cylinder. A dry graphite lubricant is the better choice for a lock cylinder. If the key is still stiff after lubricating, something is worn or misaligned, and it is worth getting it checked, because stiff locks usually fail completely before long.
My uPVC door handle is getting harder to lift. Is that urgent?
Get it looked at before it fails. Stiffness like this usually comes from the multipoint mechanism being forced against keeps that are no longer aligned. With every forced lift the gearbox is strained further, and eventually it snaps, often with the door locked shut. An alignment adjustment while the mechanism still works costs far less than replacing a failed gearbox and entering a jammed door.
Do you repair doors as well as locks?
Yes. When a lock misbehaves, the door is often the real cause. We adjust hinges, and uPVC flag hinges in particular can be raised, lowered and moved laterally; we also replace worn hinges, refit handles and spindles, and reposition keep plates so the locking points meet them properly. Do not ignore a door that closes but will not lock cleanly, as it is a security issue.
How much does a lock repair cost in Lancing?
It depends on whether the job is an adjustment or a replacement part, which component has failed, the door type and the time of day. An adjustment is normally the least expensive outcome. There is no call-out charge, and the price is agreed on the phone from what you describe. It holds unless the job on site turns out different, and then you are told before any work begins.
Should I call a locksmith, a carpenter or a handyman?
For locks, mechanisms and how a door engages with its frame, a locksmith. A handyman or carpenter can rehang a door, but will not usually be equipped to diagnose a multipoint mechanism or source the correct replacement parts, which vary a great deal by manufacturer. Not sure which applies to you? Describe the problem when you ring and we will tell you honestly.
Can you repair a lock that has been forced or damaged in a break-in?
Yes, frequently, although the extent of the damage decides it. When the police say work may begin, we check the lock, door and frame together, since break-in strain usually spreads beyond the lock. If a secure repair is impossible, we can replace it, secure the property and advise whether an upgraded cylinder would be sensible.
