Just moved in? A sensible front-door security check for your new home
The single most useful thing you can do after moving into a new place is arrange a lock change for your front door. You have no way of knowing how many keys are still out there, who the previous tenants gave spares to, or whether a letting agent, cleaner or builder ever held a copy. Changing the lock or swapping the cylinder on day one gives you a clean slate, and it is quick, non-disruptive work that we carry out while you unpack.
When we attend a new-home security check we look at the whole door, not just one lock. On a traditional timber front door that usually means confirming you have a working nightlatch for everyday use and a sound mortice deadlock for night-time and insurance purposes; many policies specify a BS3621 5 lever mortice lock, so we will tell you whether your current one meets that standard. On a uPVC or composite door we inspect the multipoint mechanism and the euro cylinder, because an old or exposed cylinder can be vulnerable to snapping.
We will also check back doors, any patio or French doors, and ground-floor windows, and talk you through sensible upgrades without pressure. If you are renting, we can advise on what a tenant is typically allowed to change versus what should go through the landlord or managing agent first. Call 020 3757 5840 to book a move-in check and we will confirm the price before we set off.
Lock change London: replacing a worn mortice deadlock or nightlatch
Locks wear out. A mortice deadlock that has turned smoothly for a decade can start to stiffen, the bolt can catch on the keep, and eventually the key becomes hard to turn or will not turn at all. A worn nightlatch may fail to latch properly, spring back slowly, or let the door drift open. These are classic signs that it is time for a lock change rather than a repair, and leaving it risks being locked out at the worst possible moment.
We fit and replace both the common British door locks: 2 lever mortice lock units for internal or lower-security doors, and 5 lever mortice lock deadlocks for front and back external doors where insurers usually want a BS3621-rated lock. For nightlatches we can match a like-for-like replacement or upgrade you to a more secure, deadlocking version. We carry a good range of stock on the van so most jobs are completed in a single visit, and we always test the new lock repeatedly before we leave.
The final quote for a lock change service depends on the type and grade of lock, how many locks you want done, the time of day, and the travel distance to your postcode. There are no hidden extras: we confirm an exact price up front once we know what you need. If you are not sure whether you need a full door lock change or just a cylinder swap, describe the problem on the phone and we will give you honest guidance.
uPVC door lock repair London: when a uPVC door won't lock
A uPVC door that suddenly will not lock is one of the most common calls we take across Wandsworth, and it is rarely the disaster it feels like. Often the door has dropped slightly on its hinges or the frame has moved in warm weather, so the multipoint mechanism no longer lines up with the keeps. In many cases this is an adjustment and lubrication job rather than a replacement, and we can have you locking the door normally again the same visit.
Sometimes, though, the multipoint gearbox itself has failed; you can usually tell because the handle lifts but the hooks and bolts no longer throw, or the handle feels loose and spongy. We diagnose which part has gone and replace the specific mechanism rather than the whole door. Separately, the euro cylinder deserves its own attention: older cylinders can be snapped, so when a cylinder needs changing we recommend an anti-snap, TS007 3-star rated replacement to close that weakness off properly.
The same thinking applies to a door lock replacement London residents need on composite doors, which share the multipoint and euro cylinder setup. If your key spins without engaging, the handle has gone floppy, or you have to lift and shove to lock up, call 020 3757 5840 and describe what the door is doing — we will bring the likely parts so we can usually fix it in one trip, with the price agreed before we arrive.
Patio doors, back doors and the entrances it's easy to forget
Front doors get all the attention, but back doors and patio doors are where a surprising amount of residential work happens. Many Wandsworth homes and garden flats have sliding patio doors or glass doors onto the garden, and these have their own locking systems that wear differently. A sliding door lock replacement is often needed when the hook bolt stops engaging the keep or the key mechanism seizes, and a glass door lock replacement on an aluminium-framed unit calls for the right hardware so the glazing is never put under stress.
Patio and French doors also use euro cylinders and multipoint mechanisms similar to a uPVC front door, which means the same risks apply: dropped doors, failed gearboxes and snappable cylinders. We service all of these, and we will tell you honestly whether a simple adjustment will do or whether the mechanism has genuinely failed. Because these doors face the garden and are less visible from the street, upgrading them is one of the most worthwhile security improvements most homeowners never think to make.
If you have a combination-style lock on an outbuilding door or a smart keypad on a side entrance, be aware that we focus on the locks fitted to the fabric of your home and the doors that secure it. For questions about resetting a keypad code — the kind of master lock change combination or Honeywell and Defiant keypad reset people ask about — the code procedure is set by the manufacturer and found in the unit's own instructions; we are happy to advise on securing the door itself when we visit.
Locked out London or lost your keys: what to change and what to leave
Losing your keys is stressful, but the response should be calm and methodical. First, check for a legitimate spare — with a trusted neighbour, a partner, or held by family — and whether another door or a ground-floor entrance is safely accessible. If you are genuinely locked out London-wide, our team can attend quickly; where possible we use damage-free entry methods so your door and lock are not harmed, and we will ask to confirm you are the lawful occupier before carrying out any work, which is standard and protects everyone.
If keys are lost rather than simply left inside, the question becomes what to change. The sensible rule is to change or replace any lock whose key is now missing and could identify your address, and to leave untouched the locks whose keys are safely accounted for. On a uPVC or composite door that usually means a cylinder change; on a timber door it may mean a new mortice deadlock, nightlatch, or both. Changing the cylinder or lock is quicker and tidier than people expect, and it restores the one thing that matters: only you hold working keys.
For a lost-key lock change we talk through which doors to prioritise so you are not paying for more than you need. The price depends on the lock types, how many doors, the time of day and travel to your postcode, and we confirm it before any work begins. Call 020 3757 5840 — we answer 24/7, including evenings, weekends and bank holidays.
Your local residential locksmith across Wandsworth and beyond
Being genuinely local matters. We know the mix of housing across the area — the Victorian terraces around Earlsfield and Summerstown, the mansion blocks and converted flats near Wandsworth Common, the newer riverside developments by the Thames, and the family homes stretching towards Southfields and Tooting. That familiarity means we turn up with the right stock for the doors we are likely to find, from traditional mortice setups to modern multipoint uPVC doors, so most residential jobs are finished in one visit.
As a mobile service we bring the workshop to your doorstep, which suits busy households, tenants and landlords alike. We regularly help letting agents and managing agents with lock changes between tenancies, assist homeowners upgrading security after a move, and carry out commercial lock change work for small shops, offices and workspaces nearby when a business needs the same trained, insured hands. Everything is quoted up front, with the call-out charge made clear on the phone before we come out.
Whatever the door and whatever the hour, you deal with one local team from the first phone call to the final test of the new lock. If you need a lock change London, a repair to a stubborn uPVC door, or help after a lockout, call 020 3757 5840 — we send a locksmith straight away and are usually with you in about 30 minutes.

Before you call — what to expect
What customers usually ask before booking
Will you be able to get into my home without damaging the door or the lock? In most cases, yes. Our experienced technicians assess the door, lock type, and situation first — whether it is a Yale-type nightlatch, a 5-lever mortice deadlock, or a multipoint lock on a uPVC or composite door — and use the least invasive method that the circumstances allow. If any controlled damage is unavoidable, we tell you before we proceed and explain exactly what replacing or repairing the lock will involve.
How do I know the person who turns up is genuine and trustworthy? When you call 020 3757 5840, we take your details, confirm the job, and send a qualified, insured locksmith to your address. Our technician will arrive in a marked van and carry identification, so you can verify who you are letting in. We never subcontract your job to someone unknown.
Is there a call-out charge on top of the final price? There is a call-out charge, and we make that clear on the phone before anyone comes out. The full, confirmed price — covering the call-out, the labour, and any parts required — is agreed with you before work begins. The factors that affect the final quote include the type of lock or door, the parts needed, the time of day, and travel distance to your postcode district.
Do you work on evenings, weekends, and bank holidays? Yes. Earlsfield Locksmith operates around the clock, every day of the year. Whether you are locked out London on a Sunday night or need a lock change London on a bank holiday Monday, you can call 020 3757 5840 and reach us directly — not an answering service.
How our quote process works — from first call to confirmed price
Step 1 — Call us on 020 3757 5840. Tell us your situation: whether it is an emergency locksmith London call-out, a door lock replacement London job, a uPVC door lock repair London, or a planned lock change London. We listen carefully and ask a few short questions about your door, lock type, and location in Wandsworth or the surrounding area.
Step 2 — We work out your quote over the phone. Based on what you describe — the lock or cylinder type, whether parts such as an anti-snap euro cylinder or a 5-lever mortice deadlock are needed, your postcode district, and the time of day — we calculate a clear, all-in price. No hidden extras are added later.
Step 3 — You confirm before we move. We state the full price to you clearly. Only once you are happy with it do we despatch a technician. There is no pressure and no obligation to proceed if the quote does not suit you.
Step 4 — The technician arrives and reconfirms the price on-site. Before touching your door or lock, the technician confirms the agreed price face to face. If anything about the job differs materially from what was described on the phone — for example, the lock type is different from expected — any adjustment is discussed and agreed with you before work starts. You will never face a surprise bill.
What to expect from the technician when they arrive
Arrival window: when you call for a 24 hour locksmith London service, we send a technician straight away. We are usually with you in about 30 minutes, though precise timing can vary with traffic on roads like Garratt Lane or the South Circular, particularly during evenings and weekends. We keep you informed if anything changes.
Marked van and identification: our technician arrives in a clearly marked van and carries identification. Before you open your door fully or allow access to a communal entrance in a block of flats, ask to see their ID — a professional technician will expect this and hand it over without hesitation.
Walkthrough of the work: before any work begins, the technician will inspect the door, the existing lock or cylinder, and the frame. They will explain exactly what they intend to do — whether that is a straightforward lock change London, a uPVC door lock repair London, a euro cylinder replacement with an anti-snap or TS007 3-star upgrade, or a full door lock replacement London — and confirm the agreed price on-site. If you have questions about the hardware being fitted, they will answer them plainly.
Tidy finish: once the work is complete, the technician will test the new lock or repaired mechanism with you present, hand over all keys cut to the new cylinder, and leave the area around your door clean and clear. If any old hardware is removed, it is taken away or disposed of tidily. Call 020 3757 5840 — we answer 24/7.

020 3757 5840Frequently asked questions
Should I change the locks when I move into a new flat or house?
Yes, it is one of the first things we would recommend. You cannot know how many keys are in circulation from previous tenants, agents or tradespeople, so a lock change or cylinder swap on your main doors gives you a clean slate. On a uPVC or composite door this usually means a new euro cylinder; on a timber door it may mean a new mortice deadlock or nightlatch.
My uPVC door won't lock even though the key turns — can you fix it without replacing the whole door?
Almost always, yes. The most common causes are a dropped door that has moved out of alignment or a failed multipoint gearbox, and we repair or replace only the part that has gone rather than the door itself. If the cylinder is the issue we will fit an anti-snap, TS007 3-star rated replacement so the weak point is properly addressed.
What is the difference between a 2 lever and a 5 lever mortice lock?
The lever count broadly reflects the security level: a 2 lever mortice lock is suited to internal doors or lower-risk uses, while a 5 lever mortice lock is the standard for external front and back doors. Home insurers often specify a BS3621-rated 5 lever deadlock on final exit doors, so when we attend we will tell you whether your current lock meets that requirement.
How quickly can you reach me if I'm locked out in Wandsworth?
We send a locksmith straight away and are usually with you in about 30 minutes, depending on traffic and where you are in the area. We operate 24/7, including evenings, weekends and bank holidays. Before anyone sets off we confirm the call-out charge and the likely price on the phone.
Will you damage my door to get me back in?
We use damage-free entry methods wherever possible, so in most cases your door and existing lock are left intact. Occasionally a lock has failed internally and a replacement is unavoidable, but we will always explain the situation and the options before carrying out any work. We also ask to confirm you are the lawful occupier first, which is standard practice.
Do you reset keypad or combination door locks like Defiant, Honeywell or Master Lock units?
The code-change procedure for keypad and combination locks is set by the manufacturer and found in that unit's own instruction manual, so following those steps is the correct route for resetting a code. What we focus on is securing the door itself — the mortice locks, cylinders and multipoint mechanisms fitted to your home — and we are happy to advise on that when we visit.
How much will a lock change cost?
We do not quote a single flat figure because the final price depends on the type and grade of lock, how many doors you want done, the time of day and the travel distance to your postcode. What we promise is clarity: we confirm an exact up-front price, including the call-out charge, on the phone before any work begins. Our technicians are trained and fully insured.
Do you only work on homes, or can you help a small business too?
We mainly serve residential customers across Wandsworth, but we also carry out commercial lock change work for small shops, offices and workspaces nearby. The same trained, insured team handles both, and we confirm the price before we attend. Call 020 3757 5840 to discuss what you need.
