What Decides the Price of a Locksmith Job
The price of a locksmith job is decided by six things, and none of them is your postcode. The job itself, the parts it needs, the door it is on, the hour you ring, whether the lock can be saved and how many doors are involved together set the figure, and a locksmith who knows the trade can give you that figure on the phone before travelling. This guide explains each one, so you can tell a fair quote from a vague one.
Written by Sam Gregory, locksmith in Sheffield. Updated October 2026.
Why the Same Job Costs Different Amounts
Two people can ring about the same locked door and be quoted differently without either being overcharged. The difference is what the job turns out to involve once somebody looks at it.
A door that is simply locked needs opening. A door whose mechanism has snapped inside needs opening and then a part. A door that has been forced needs opening, a part and often a repair to the frame. Those are three jobs, not one, and they are priced as three jobs.
This is why a locksmith who quotes a single flat figure for anything without asking a question is either guessing or planning to revise it at your door. The questions are the work.
The Six Things That Move the Figure
Six variables decide what any domestic lock job costs. They are listed here in the order they usually matter.
- The job itself, because opening a door, changing a cylinder and replacing a full mechanism are three different pieces of work with three different amounts of labour in them.
- The parts, which is the largest single variable. A euro cylinder, a handle set, a gearbox and a full multipoint strip are four different items at four very different costs.
- The door type, because a composite door is heavier and takes longer to set right than a uPVC one, and a wooden door with a mortice lock is different work again.
- The hour, since work at two in the morning is not priced the same as a Tuesday afternoon, and it should not be.
- Whether the lock survives, which is decided at the door. A lock that opens and still works costs less than one that has to be replaced afterwards.
- How many doors are involved, because a whole house of locks is quoted as one job rather than as four separate visits.
Notice what is not on that list. Your postcode, the make of your car on the drive and how urgent you sound are not pricing factors, and a quote that moves when any of those change is a quote worth questioning. The part that matters most is the second one, which is why mechanism replacement in Sheffield costs more than a cylinder swap on the same door.
Why the Part Matters More Than the Labour
On most domestic lock jobs the part is the larger half of the price, which surprises people who assume they are paying for time.
- A euro cylinder is the cheapest common part and the quickest to fit, which is why a lock change after a lost key is the least expensive job on the list.
- A handle set costs more than a cylinder and is often fitted with one, because a strong cylinder behind a weak handle protects nothing.
- A gearbox is the component inside a multipoint mechanism that actually fails, and replacing just the gearbox is cheaper than replacing the strip it sits in.
- A full multipoint mechanism is the most expensive common part, and it is the one quoted when the strip itself is worn rather than the gearbox inside it.
The practical consequence is worth knowing before you accept a quote. A locksmith who replaces the whole mechanism when the gearbox alone has failed has charged you for the expensive part when the cheaper one would have done, and that is a real difference rather than a small one.
What a Call Out Fee Actually Is
A call out fee is a charge for travelling to you, added before any work starts and whether or not the job gets finished. It is separate from the price of the work.
Some locksmiths charge one and some do not, and neither is dishonest as long as you are told. What makes it a problem is finding out about it afterwards, which is why it belongs in the first thirty seconds of the phone call rather than on the invoice.
The same goes for VAT. A business only charges VAT once its turnover passes the registration threshold, so a smaller locksmith may not add it at all. A quote that is about to grow by a fifth is a different quote, and you are entitled to know which one you have been given.
Why Night Work Is Priced Differently
Overnight and late evening work costs more, and the reason is simple enough that it is worth stating plainly rather than hiding in a surcharge.
A locksmith answering the phone at two in the morning is working a shift nobody else wants, and the job will usually be a lockout, which is the least profitable work in the trade. If night work were charged at the daytime rate, almost nobody would answer the phone at night, which is worse for the person stood outside.
What matters is that the night figure is given before the locksmith sets off rather than after the door is open. A price quoted to somebody who is cold, locked out and out of options at three in the morning is not a price anybody can refuse, and that is exactly when it should be fixed in advance.
Four Questions to Ask Before Anybody Travels
These four questions take under a minute and tell you more about a quote than any figure on its own.
- Is the call out included, or is it charged on top of the work.
- Is VAT included in that figure, or does it go on afterwards.
- Does the price include the parts, or are those extra once you see the door.
- What happens if it cannot be fixed, and do I pay anything then.
A locksmith who answers all four without hesitating has thought about pricing and is telling you the truth about it. One who will not answer until they have seen the door is telling you something too.
What to Do When a Price Changes
A quote can legitimately change, because a locksmith cannot see inside your lock over the phone. What matters is when you are told and whether you can still say no.
A change explained before any work starts, with the reason given and the option to decline, is fair. A change announced once the door is open, or once the old lock is already out, is not, because by then refusing costs you more than agreeing.
If it happens, ask for an itemised invoice showing labour and parts separately and pay by card rather than cash so there is a record. If the final figure is higher than the quote and nothing was said before the work started, you are entitled to challenge it, and an itemised invoice is what you need in order to do that.
Get a figure before anybody travels
Send a photo of the door from the outside with the lock and the handle in frame. Sam replies with what the job needs and what it will cost, before he gets in the van. If you are locked out right now, call or WhatsApp him instead.
Jobs Where These Variables Play Out
Each of these pages describes a job in full, including which of the six variables moves its price most.
Where the hour you ring matters more than anything else.
Where the part is a cylinder and the labour is short.
Where the cylinder and the handle are quoted together.
Where the door and the frame both need attention.

How much does a locksmith cost per hour
Most domestic locksmiths do not charge by the hour, because the part is usually the larger half of the price. A job is quoted as a job, which is why the figure depends on what the job turns out to be rather than how long it takes.
Why do locksmiths charge so much
Because the part is often the bigger half of the bill, and because a mobile trade carries its stock, its van and its waiting time inside the job price. A lock change that takes twenty minutes still includes the cylinder, the travel and the fact that nobody was earning while driving to you.
Is an emergency locksmith free
No. Some locksmiths quote without charging for the quote, and some charge nothing when a job cannot be completed, but the work itself is never free. An offer that sounds free usually means the charge appears somewhere else.
Should I pay a call out fee
That is your decision, and the only wrong version is not being told. A call out fee is a charge for travel, added before any work starts, so ask whether there is one in the first thirty seconds of the call rather than finding out on the invoice.
Is it cheaper to change a lock myself
Sometimes, for a simple cylinder swap on a uPVC door, if you measure it correctly. The common mistake is buying a cylinder the wrong length, which either leaves it standing proud of the handle and easy to snap or stops the door locking at all. The measuring is the skill rather than the fitting.
Does the time of day change the price
Yes. Overnight and late evening work is charged differently from a weekday afternoon, and it should be. What matters is being told the night figure before the locksmith sets off rather than after the door is open.
Can a locksmith quote over the phone
Yes, for most jobs, if they ask the right questions. Door type, what the lock is doing and what the key does are usually enough. A photo of the door from the outside makes it more accurate still.
What if the price changes when they arrive
A change explained before any work starts, with a reason and the option to decline, is fair. A change announced once the door is open is not. Ask for the reason, and remember you can still say no at that point.
Should I get a written quote
For anything that is not an emergency, yes, and a message or an email is enough. For a lockout, a figure agreed on a recorded call is what you have, which is another reason to settle it before anybody travels.
Why is a full mechanism more than a gearbox
Because it is a much larger part. A gearbox is the component inside the mechanism that usually fails, and replacing only the gearbox costs less than replacing the whole strip. Ask which one you are being quoted for.
Do all locksmiths charge VAT
No. A business only charges VAT once its turnover passes the registration threshold, so a smaller locksmith may not add it. Ask whether the figure includes it, because a quote that grows by a fifth is a different quote.
What does no fix no fee actually mean
That you pay nothing if the job cannot be completed. It is worth asking about specifically, because it is the one term that only matters on the day something goes wrong.
How do I get a price for my own door
Describe what the lock is doing rather than what you think is wrong with it, and send a photo of the door from the outside with the lock and handle in frame. Every way of reaching Sam is on the contact page.
