You call a locksmith because you're locked out, or your front door won't turn, or you've lost a key—and then the quote comes through and you do a double take. The number can be genuinely surprising. But it's rarely random. There are real reasons why one locksmith job might cost £80 and another £250, and understanding those reasons means you'll know whether you're getting fair value or not.
Most locksmiths charge a callout fee first, then labour, then parts. In Datchet, you're typically looking at £50–£100 just to get someone round to assess the job. That's not unusual—a technician's time has a cost, and they're coming to your home or business during working hours (or charging more if it's late evening). After that, labour usually runs £50–£150 per hour depending on the complexity of the work.
But here's the thing: the callout fee often gets absorbed into the final bill if you go ahead with the work. So if the job takes 45 minutes and costs £80 labour, you're not paying the callout on top of that—it's already factored in. Always ask about that upfront when you ring around.
A simple lock cylinder replacement will be on the lower end. If your back door lock has worn out and needs a new barrel, that's straightforward: maybe £100–£150 total, depending on the lock type. Parts are cheap; the work is quick.
Where costs climb is when the job is fiddlier. If you're locked out of a uPVC door and the lock's seized, the technician might need to pick it without damaging the frame—that takes skill and time. A broken lock that's jammed inside the mechanism, or a door that's warped and won't accept a new lock properly, means more labour. Emergency calls—say, you're locked out at 11 p.m.—will typically cost 50–100% more than daytime rates.
If you need multiple locks done—say, rekeying all the doors in a rental property—that's a bigger job with a better per-lock rate, but the total bill will reflect that scale. Read more here on how to think about lock jobs across your whole property.
Locks themselves vary wildly in price. A basic nightlatch might be £15–£30, but a high-security cylinder or a modern smart lock could be £80–£200+. The technician will often show you options and let you decide. Don't assume the most expensive lock is the best—sometimes a mid-range lock from a reputable manufacturer is exactly what you need.
If you need replacement keys cut, that's usually £5–£15 per key depending on the lock type. Reinforcement plates if your door frame is weak, or a new strike plate? Add another £20–£40. These extras add up, but they're often worth it—especially in Datchet where flooding and damp can soften door frames over time, making proper installation and reinforcement genuinely useful.
Ring three locksmiths in the area and get quotes. Yes, three. Tell them exactly what the problem is: 'I'm locked out of my front door uPVC lock' or 'My back door deadbolt won't turn and I think the mechanism's worn.' The more specific you are, the more accurate the quote will be.
Ask what's included: is the callout fee separate or absorbed? Do they provide a written quote before starting work? Will they show you the parts and give you a choice? A good locksmith will do all of those things. Find out more about what to look for when choosing a locksmith.
If a quote seems wildly lower than the others, be cautious—they might be offering stripped-down work or poor-quality parts. If one's significantly higher without obvious reason, ask why. Locksmiths aren't all the same, but they should be roughly aligned.
Access. If the technician has to force entry because you're locked out and can't access the lock from outside, that's extra work and potential damage repair. If your door is particularly old or non-standard, they might need specialist tools. Damage assessment—maybe the lock is fine but the frame's damaged—means additional work to make the repair hold.
If you need work done urgently, say it clearly. Same-day emergency calls are pricier, but sometimes they're worth it, especially if you've got a business at risk or family locked out. This article explains when timing really affects your options.
One thing many people underestimate: if you're rekeying after a break-in or lost keys, that's usually more thorough than a simple lock repair, and it takes longer. Factor that in.
For a straightforward lock repair or replacement in Datchet, budget £100–£200. For emergency work outside standard hours, add 50% to that. If you're securing multiple doors, expect £200–£400 depending on how many locks and what type. Smart locks or high-security installations will push higher.
The real thing to remember: you're paying for skill, not just a lock. A good locksmith knows how to install a lock so it actually works, handles awkward doors without damaging them, and will give you honest advice about whether you actually need the expensive option. That's worth the money.
