Key Control: Who Has Access to Your Home?
Managing key distribution and knowing exactly who can enter your property.
Need to change your locks? We do that every day. New locks, new keys, same-day where possible — you choose who has a key.
It's a quiet question worth asking. If you can't account for every key to your home, it's time to change locks — your home isn't fully under your control.
Previous owners, former tenants, cleaners, dog walkers, neighbours with spare keys — you have no idea how many copies of your keys exist. The estate agent didn't collect them all. That's why front door lock replacement is the first thing smart homeowners arrange when moving into a new house.
That missing key set could be anywhere. If your address was on the keyring — or someone knows where you live — your home is vulnerable right now. Don't wait to find out who has your keys.
When trust breaks down, lock security becomes personal safety. Whether it's a partner, housemate, or family member — if the relationship has ended and they have keys, you deserve to feel safe in your own home.
Keys that stick, grind, or need jiggling are warning signs. A lock that's hard to operate is on its way to failing completely — often the day you're in a rush. Replace it before it leaves you locked out or locked in.
After a break-in, your locks might look fine — but are they? Burglars often damage mechanisms in ways that aren't visible. More importantly, they know your home now. New locks are part of reclaiming your sense of safety.
Renovation work often means handing over keys to multiple people — plumbers, electricians, decorators. When the work is done, how many copies are still out there? Changing locks closes that chapter cleanly.
Priorities shift when little ones arrive. That nagging thought about who has spare keys suddenly feels more urgent. New locks give you the certainty that your home is secure for your growing family.
When you're responsible for a parent's home, lock security matters more than ever. Old locks that "they've always had" may be weak points. Upgrading their security shows you care — and gives everyone peace of mind.
Cleaners, dog walkers, contractors who finished, friends who minded the house — every key you handed out and didn't get back is still out there. People mean well, but life moves on. Reset key control without the awkward chase-up.
There's a difference between swapping a lock and upgrading your security. Here's exactly what's included on every Trulox lock replacement — in writing, before we start.
Simple, transparent, on your schedule. Here's exactly what happens when you call.
Quick call or message. Whether you've just moved in, lost keys, or want a security upgrade, we understand your situation and explain your options clearly. No jargon, no pressure.
~2 minutesSame-day where possible, or scheduled to suit you. Our engineer arrives with the tools and a selection of BS3621-standard locks ready to fit. Whether it's a planned upgrade or you need locks changed today, we come to you.
You choose the timeWe inspect your existing locks and door, then explain your options clearly. We'll tell you if your current lock is adequate, or recommend upgrades if there are genuine vulnerabilities. Honest advice, no upselling.
~5 minutesClean, precise fitting that aims to avoid damage to your door or frame. We take care to protect your property and clean up after ourselves. The new lock is tested thoroughly before we consider the job done.
10-30 min per lockYour new keys work cleanly from the first turn. The old ones are now useless — you choose who has a key from this point on. We only take payment once everything's tested and you're satisfied.
Peace of mindFrom standard cylinders to specialist multipoint systems — we carry and fit them all, including Yale, ABS, Mul-T-Lock, Avocet and Ultion.
The standard lock barrel for uPVC and composite doors. Our lock cylinder replacement service fits quality anti-snap, anti-pick, anti-bump cylinders that resist the most common attack methods. Available in various sizes to match your door.
Traditional security for wooden doors. We replace 5-lever BS3621 certified locks—the standard most insurers require. If your lock doesn't meet this standard, upgrading could improve your insurance position.
Full-length locking mechanisms for uPVC and composite doors. We can replace the entire gearbox, individual hooks and rollers, or just the cylinder—depending on what's needed.
Modern cylinders with sacrificial break-off sections. If an attacker snaps the cylinder, the inner section stays in place—keeping your door locked. On uPVC and composite doors this TS007 3-star rating—not BS3621—is the security benchmark insurers look for.
Need to replace your Yale lock? Rim-mounted nightlatches for secondary security or convenience. We supply and fit Yale and British Standard nightlatches. A good nightlatch complements a primary deadlock but shouldn't be used alone for security.
Heavy-duty cylinders and access control for business premises. We understand the specific requirements of landlords, letting agents, and commercial properties—including master key systems.
One call, everything handled. Professional lock fitting service with no unexpected extras. New locks fitted, new keys, complete peace of mind.
Old locks removed carefully without damaging your door or frame. We handle even seized or corroded locks without causing additional problems.
Quality replacement installed to manufacturer specifications. Properly aligned, correctly sized, and functioning smoothly from day one.
Multiple keys included with every new lock—typically 3-5 depending on the cylinder. No need to pay extra for copies.
No mess, no debris, no metal filings on your doorstep. We clean up after ourselves and leave your property exactly as we found it—except more secure.
Honest assessment of your overall door security. If there are vulnerabilities we can see, we'll point them out—without pressure to buy anything.
Quality locks backed by manufacturer warranty. Plus our workmanship guarantee—if there's ever an issue with our installation, we return to make it right.
Real stories from people who took control of their home security.
We had a break-in last month and I was a complete mess afterwards. Trulox came out same day to board up and change all the locks. What I appreciated most was they didn't rush me - took time to explain what they were fitting and why. Made me feel safe in my own home again which sounds dramatic but it's true. Would definitely recommend to anyone in a similar situation, they really do care.
Danny was very helpful and explained everything that he suggested needed doing to effect my door lock repair. Where there were choices for me to make, he explained in detail the benefits of each lock. He told me the cost of each solution and left it for me to decide. I am really happy with the finished work. Thank you.
I had George from Trulox, come and fix the lock on my door. He came out the same day and was friendly, professional and conscientious. I was very happy with the job he did and would highly recommend.
Making the right decision for your home security.
Yes — it's the single most important security step for any new homeowner. You have no way of knowing how many keys exist for your current locks: previous owners, tenants, cleaners, or neighbours may still have copies. Changing locks when you move in gives you complete control over who can access your home.
Budget locks are often made from softer metals and have simpler mechanisms that are vulnerable to snapping, picking, and bumping attacks. Quality anti-snap cylinders include hardened steel pins and sacrificial break-off sections that keep you secure even during an attack.
In some cases, yes—this is called "keying alike." If you have multiple doors and want one key for all, we can supply cylinders that work with the same key. We'll discuss your options during the assessment.
A standard cylinder replacement typically takes 10-30 minutes per lock. More involved jobs like multipoint mechanism changes can take longer. We always give you a realistic timeframe before starting.
Usually for the better. Most insurers require BS3621 locks on external timber doors (uPVC and composite doors use TS007 3-star anti-snap cylinders instead). We can advise whether your current locks meet the standard and fit compliant replacements if needed — which can improve your insurance position.
If you're changing locks for security reasons—like lost keys or moving home—it makes sense to do them all at once. We offer competitive rates for multiple locks and can ensure consistent security across all entry points.
We remove and dispose of old locks responsibly. If you prefer to keep the old cylinder (some landlords require this), just let us know and we'll leave it with you.
Absolutely. We can add security features like anti-snap cylinders, reinforced strike plates, or additional locks. We'll assess your door and make honest recommendations—no pressure to buy anything you don't need.
Yes, we're happy to fit customer-supplied locks. Just be aware that we can only warranty our workmanship, not the lock itself. If you're unsure what to buy, we can advise on the best options for your door.
This is a common request and usually straightforward to arrange. We can supply cylinders "keyed alike" so one key opens multiple doors of the same lock type. It's convenient and doesn't compromise security.
Lock replacement starts from £79, and there's no call-out fee — you only pay if you accept the quote. The exact price depends on the lock type and how many locks you need, so it varies by lock; we confirm the full price with you before any work begins.
Same-day lock changes are often possible, depending on your area and what time you call. We're open until midnight, so even an evening call can usually be arranged quickly. If we can't make it the same day, we'll book the soonest time that suits you.
Trulox is independent and family-run — the engineer who quotes is the engineer who fits your locks. Here's what we put in writing on every replacement.
Every job comes with a 12-month workmanship warranty in writing. If the same problem returns and it is down to how we fitted it, we come back and put it right at no charge.
You'll know the exact cost before any work starts — lock type, labour, everything included. No call-out fee, and the price we agree is the price you pay. You only pay if you accept the quote.
Mortice locks fitted to BS3621 — the standard most UK home insurers list. Anti-snap cylinders fitted to TS007 3-star where required. Quality cylinders by Yale, ABS, Mul-T-Lock, Avocet and Ultion stocked on the van.
