How Much Does Lock Repair Cost In 2026?
Lock repair in the UK costs £70–£150 inc VAT for a typical job, climbing to £90–£180 in London and the South East. Most household lock faults — a stiff cylinder, a dropped uPVC handle, a latch that will not catch, or a misaligned door — are resolved in under an hour, which keeps them near the middle of that range.
The main driver is what has failed and whether it needs a part. Adjusting a strike plate, freeing a sticky lock, or realigning a door is often labour only. Replacing a worn gearbox in a uPVC multi-point mechanism, a broken euro cylinder, or a failed mortice lock spring means a part on top of the labour. Time of day matters too: an evening or weekend call-out carries an out-of-hours premium.
Here is what lock repair typically costs across the UK:
| Repair | Rest of UK | London & South East |
|---|---|---|
| Minor adjustment (alignment, sticking latch) | £70 – £110 | £90 – £140 |
| Cylinder or handle repair/replacement | £90 – £150 | £120 – £180 |
| uPVC multi-point mechanism repair | £120 – £250 | £160 – £320 |
| Out-of-hours repair | £110 – £200 | £150 – £260 |

Lock Repair Cost By Lock Type
Different locks fail in different ways, and the parts vary in price. This breakdown shows typical costs by lock type:
| Lock type | Common fault | Typical repair (rest of UK) |
|---|---|---|
| uPVC euro cylinder | Sticking, key won't turn | £80 – £150 |
| uPVC multi-point mechanism | Handle drops, won't lock | £120 – £250 |
| Mortice lock (wooden door) | Worn, seized, key jams | £90 – £170 |
| Night latch (Yale-type) | Latch won't catch, worn | £70 – £140 |
| Window or patio lock | Stiff, misaligned | £70 – £130 |
| Door alignment / strike plate | Door dropped, won't close | £70 – £120 |
Where the broken key has damaged the cylinder, or the mechanism is worn out, a repair may tip into a full replacement.
What Affects The Cost Of Lock Repair?
1. The Type Of Lock
A basic night latch is cheap to work on. A uPVC multi-point mechanism, with its gearbox, hooks and rollers, is more complex and its parts cost more — the most common driver of a higher bill.
2. The Fault
An alignment tweak or a sticking latch is quick and often labour only. A seized gearbox, a snapped spring or a worn cylinder needs a replacement part, adding to the total.
3. Whether Parts Are Needed
Labour-only fixes sit at the low end. Once a cylinder, gearbox or handle set is required, the part price is added — a euro cylinder from around £75, a uPVC gearbox from around £40–£120.
4. Time Of Day
Standard daytime labour is around £65–£95 per hour. Evenings, weekends and bank holidays rise to roughly £110–£130 per hour, adding about £40–£90 to an out-of-hours repair.
5. Repair Vs Replace
Some faults are cheaper to fix; others make replacement the better value. A locksmith will advise when a worn lock is not worth repairing and a new one will last longer.
6. Your Location
London and the South East run roughly 15–30% higher than the North of England, Wales and Scotland, reflecting higher labour rates.
What's Included — And What's Not
Typically included in a repair quote:
- Attendance and diagnosis of the fault (no call-out fee with a fixed-price provider)
- Labour to adjust, free or repair the lock
- Minor consumables such as lubricant and fixings
- A test of the lock and door once the repair is done
Usually charged separately:
- Replacement components (cylinder, gearbox, handle, mortice case)
- A full lock replacement where repair is not viable
- Security upgrades fitted at the same time
- Any out-of-hours premium
Ask the locksmith to confirm the fault, the fix and any parts before work starts, so the bill matches the quote.
Can You Do It Yourself?
Plenty of minor lock issues are within reach of a confident DIYer. A sticky lock often just needs a graphite or PTFE lubricant (never oil, which attracts grit). A door that has dropped and will not close can sometimes be fixed by adjusting the hinges or the strike plate. A loose handle usually needs its screws tightened or a new fixing.
Where DIY gets risky is inside the mechanism. Replacing a uPVC gearbox, fitting a new mortice case or swapping a cylinder to the right size takes the correct measurements and parts — get it wrong and the door will not lock, or the lock will be easy to defeat. Forcing a seized mechanism can snap it entirely. For anything beyond lubrication, tightening and simple alignment — especially a uPVC multi-point fault or a lock that has failed on your only door — a locksmith is faster and avoids turning a repair into a replacement.
How To Save Money On Lock Repair
- Act early — a sticky or stiff lock caught early is a cheap adjustment; ignored, it fails and needs parts.
- Lubricate locks twice a year with graphite or PTFE lubricant to prevent most sticking and seizing.
- Fix a dropped door promptly — running a strained multi-point mechanism wears out the gearbox, the priciest part to replace.
- Book in standard hours where it is safe to wait, to avoid the out-of-hours premium.
- Ask repair vs replace — a good locksmith will tell you when a repair is a false economy on a worn-out lock.
- Get a fixed price up front covering diagnosis and any parts, with no call-out fee.
How To Hire A Good Locksmith
A skilled locksmith repairs where sensible rather than defaulting to a costly replacement, so choose carefully. Look for a locksmith who is a member of, or approved by, the Master Locksmiths Association (MLA) — MLA-approved locksmiths are vetted, qualified and insured. Confirm public liability insurance, ask for reviews or references, and insist on a fixed price up front with no call-out fee.
Be cautious of anyone who reaches for a drill or recommends a full replacement before diagnosing a fault that may be a simple adjustment. With Fantastic Services, you get vetted, insured locksmiths, a fixed price agreed up front and online booking, so a repairable lock gets repaired without unnecessary spend.
Frequently Asked Questions
How Much Does It Cost To Repair A Door Lock?
Door lock repair costs £70–£150 inc VAT for a typical job in 2026, or £90–£180 in London. Minor adjustments sit at the lower end, while a uPVC multi-point mechanism repair or a job needing parts costs more.
Is It Cheaper To Repair Or Replace A Lock?
It depends on the fault and the lock's condition. Minor faults — alignment, a sticking latch, a loose handle — are cheaper to repair. A worn-out or badly damaged lock is often better replaced, as a repair may not last. A locksmith will advise which is the better value.
Why Won't A UPVC Door Lock When The Handle Drops?
A uPVC handle that lifts but won't lock, or drops without engaging, usually points to a failing multi-point gearbox. This is a common fault and repairable by replacing the gearbox, typically costing £120–£250 including the part.
How Much Does It Cost To Fix A Lock That Won't Turn?
A lock where the key sticks or won't turn is often fixed by cleaning and lubricating the cylinder, or by replacing a worn cylinder. Expect £70–£150 depending on whether a new cylinder is needed and the lock type.
Can A Sticking Lock Be Fixed Without Replacing It?
Often, yes. Many sticking locks just need cleaning and lubricating with a graphite or PTFE product. If the cylinder is worn internally, replacing just the cylinder — rather than the whole lock — is usually enough.
Does Lock Repair Cost More Out Of Hours?
Yes. Evening, weekend and bank-holiday call-outs carry a premium of roughly £40–£90 over the standard daytime rate. If the door still locks and it is safe to wait, booking a standard-hours visit costs less.
