What does a lock change cost in 2026? Real UK prices
In 2026 a straightforward lock change in the UK typically costs around £80–£140 fitted, depending on the lock type, the security grade and where you live. A simple repair is often less; an anti-snap or high-security upgrade is more. The figure should always be a fixed quote you approve before any work starts — never a number that grows once the locksmith arrives.
Market rates vary widely. Our price: a fixed quote before any work starts — lock change / replacement from £99, total price — no VAT added.
- Typical UK lock change: around £80–£140 fitted for a standard cylinder.
- A repair is often enough — plenty of "broken" locks do not need replacing.
- The honest test of any quote: one total figure, agreed before work starts.
Most locksmiths will not publish a number. We publish all of ours — and explain everyone else’s. The honest truth about a lock change is that the price is not a mystery: it comes down to six plain variables, and every one of them can be settled before anyone touches your door.
How much does a lock change cost in 2026?
A typical single-door lock change in 2026 costs roughly £80–£140 fitted, with a simple repair often coming in lower and a high-security upgrade higher. The table below sets the typical UK bands beside our own fixed prices so you have a yardstick for any quote, from anyone.
Every range in the left column is for a single door, compiled from national trade pricing. Our figures sit apart from it on purpose: the market gives you a range, and only the quote you approve gives you a commitment.
| Job | Typical UK range | What it covers |
|---|---|---|
| Lock repair | £60–£110 | A sticking or failing lock serviced and repaired — often the lock does not need changing at all. |
| Standard lock change (euro or rim cylinder) | £80–£140 | A quality cylinder supplied and fitted, keys cut, tested with you watching. |
| Anti-snap upgrade (TS007 3-star) | £110–£180 | Defeats lock-snapping, the commonest uPVC break-in method. Keys plus a security card. |
| High-security tier with a door health check | £160–£260 | A top-grade cylinder, plus hinges, keeps and alignment checked, with a written summary for your insurer. |
What actually moves the price?
Six honest variables move it, and every one of them is settled in your fixed quote rather than discovered at the door. None of them is a surprise; all of them are explainable in a sentence.
- The lock itself. A euro cylinder is a quick swap. A five-lever mortice set into a timber door is more labour. A rim nightlatch sits in between.
- The security grade. Standard, anti-snap TS007 3-star, or high-security with protected keys — better hardware costs more, and we tell you when you genuinely do not need it.
- The door’s condition. A dropped uPVC door or a swollen timber door may need adjusting so the new lock actually works. Named in the quote if so.
- How many doors. A whole-house change after a move costs less per door than four separate visits.
- Keys and convenience. Extra keys, or “keyed alike” so one key opens every door — small parts cost, quoted up front like everything else.
- When you book. Planned daytime changes are at the prices above. Emergency evening work (6pm to midnight) carries the published evening difference — see the full price list.
How do I read a quote so a low advert never becomes a £700 bill?
Turn every “from” price into a single total before anyone travels, and a low advert loses its teeth. The number that gets you to dial is not the number you pay unless it is fixed for your job, in writing, first.
Here is how a tempting headline figure quietly grows once someone is standing in your hallway, and the one question that stops each move.
| What you are told | What it really means | The question that stops it |
|---|---|---|
| ”Call-out from £—“ | A hook to start the call, not a price for your job. | ”What is the total, all in, for my actual door?" |
| "Plus parts and labour” | The real cost is being kept off the headline figure. | ”Put the full total in writing before you set off." |
| "It will have to be drilled” | A faster job and a second sale — a new lock at their price. | ”Will you try non-destructive entry first?" |
| "We are a local firm” | Often a national call centre reselling your job. | ”What is your company name and number?” |
The honest position is simple: we never advertise bait pricing, and the figure you approve on the phone is the figure on your card receipt. The full pattern — the warning signs and the questions that expose them — is in our companion guide on how to avoid locksmith scams.
When is a repair the right call instead of a change?
When the mechanism is worn or sticking but not broken, a repair is usually the right call — and the cheaper one. Plenty of locks sent for “replacement” only need servicing, realigning or a single worn part.
A change makes sense when keys are lost or unaccounted for, after a move or a break-in, when the lock no longer meets your insurer’s standard, or when the door has been forced. If you are unsure which your door needs, that is exactly the kind of thing worth a two-minute phone call before you spend anything.
What to ask before you say yes
Before you agree to any lock change, run the quote through a short check. An honest firm welcomes every one of these questions; the answers are where a fair price and a rip-off part company.
A fair “from £—” price comes with a fixed quote for your job before anyone travels. The unfair kind is answered with one sentence: “So what will my job cost, all in, total price, before you set off?” If a firm will not commit to its own number, that tells you what you need to know.
The bottom line on cost
A lock change is a small, knowable job. The price moves for honest reasons — the lock, the grade, the door, the keys, the timing — and every one of them can be named and agreed before any work starts. If a quote cannot be turned into one total figure on the phone, the problem is not the lock. It is the locksmith.
For the higher-security options, our written door health summary is built to support an insurance claim, and you can always confirm the standard your policy needs in our guide to BS 3621 and insurance requirements.
Questions people ask us
Is it cheaper to buy the lock myself and have you just fit it?
Usually not by much, and sometimes it costs more. We buy hardware at trade prices, and the commonest DIY mistake — a cylinder a few millimetres the wrong size — means a second trip to the shop or a lock that sits proud of the door, which is a snapping risk. If you already own the right lock, we will happily give you a fixed quote for fitting only.
Why are evening prices higher than daytime?
Evening rates apply to emergency work between 6pm and midnight, not to planned jobs. A planned lock change is booked in daytime hours, so the daytime figures are exactly what you pay. Nobody needs an emergency rate for a job that can wait until Tuesday morning, and we will say so rather than upsell you a call-out.
Will my home insurance pay for a lock change?
Often, yes — after a burglary or stolen keys, many home policies include lock replacement cover. Check your schedule for wording such as 'replacement locks'. We support the claim properly: an itemised invoice every time, total price, no VAT added, plus a written summary of what was fitted on the higher-security options. Always confirm the detail with your own policy wording.
How long does changing a lock take?
A standard euro cylinder swap is usually a 30–45 minute job once the locksmith is with you. A multipoint mechanism or a five-lever mortice set into a wooden door takes longer because there is more to fit and test. Whatever the job, the time and the price are settled in your quote before any work starts.
Do I need to change the whole lock or just the cylinder?
Often just the cylinder. On most uPVC and composite doors the multipoint mechanism is fine and only the cylinder needs swapping — much cheaper than a full lock change. We will tell you honestly which one your door needs, and quote the smaller job whenever it is the right one rather than the bigger one.
