Woolwich is two locking worlds in one SE18 postcode. In the Royal Arsenal Riverside apartments the upgrade is usually a single TS007 3-star euro-cylinder swap on a sealed multipoint door — not a whole new mechanism. Around Woolwich Common and General Gordon Square the older terraces and ex-council flats need a full BS3621 mortice or multipoint gearbox change. This page is the guide to which lock change yours actually needs.

Woolwich SE18 · Lock Change & Upgrade
Lock change in Woolwich — the upgrade-vs-replace decision, done same day.
Woolwich is two locking worlds in one SE18 postcode. On one side sit the Royal Arsenal Riverside new-builds — Berkeley and Barratt towers along No.1 Street and Arsenal Way with composite and aluminium entrance doors on sealed multipoint gearboxes. On the other are the older terraces, Victorian conversions and ex-council flats around Woolwich Common, General Gordon Square and Woolwich New Road. The right lock change is completely different for each — and getting that call right is what this page is about.
In a Royal Arsenal flat the practical job is almost never a whole new mechanism. The multipoint strip is sound, so the upgrade is a single euro-cylinder swap — usually to a TS007 3-star anti-snap cylinder. Communal entrances run fob and concierge access-control, so there is a clear line between your resident door (which we change) and the communal door (handled by building management). On an older Woolwich Common terrace it is the opposite story: a worn BS3621 5-lever mortice coming out for a fresh kitemarked unit.
For the timber front doors around Woolwich Common, General Gordon Square and the Bathway Quarter, we fit BS3621 5-lever mortice deadlocks from £180 plus a quality nightlatch. For 1990s–2000s uPVC and ageing ex-council multipoint doors, we diagnose gearbox versus cylinder first — a standard euro cylinder change is from £135, an anti-snap upgrade from £200, and a full gearbox swap from £350 only if it is truly the gearbox that has failed.
Buying or moving in? End-of-tenancy or completion-day rekeys around the Powis Street conversions and General Gordon Square are a weekly job for us — Greenwich's private-rented licensing rules push managed-property landlords toward documented lock changes between tenancies, and our receipts list the lock model, date and key count for the file. Whether you're moving in, ending a tenancy, or just want an honest fixed quote for an anti-snap upgrade, book a same-day slot. From £89 fitted, fixed price first, no call-out fee.
What We Change in Woolwich
Six lock-change jobs we do day-in, day-out across SE18.
From a single TS007 cylinder swap on a Royal Arsenal entrance door to a full BS3621 mortice on a Woolwich Common terrace — same engineer, same fixed-price-first promise, and honest upgrade-vs-replace advice on every door.
TS007 3-star cylinder upgrade
The signature Royal Arsenal Riverside job — the sealed multipoint mechanism stays, and we swap the cylinder for a TS007 3-star anti-snap unit (Ultion, Avocet ABS, Yale Platinum). Upgrade, not replace, with new keys for your resident door.
From £200 fitted
BS3621 mortice change
5-lever kitemarked mortice deadlock for the older timber front doors around Woolwich Common, General Gordon Square, Woolwich New Road and the Bathway Quarter. Insurance-grade and paperwork-ready.
From £180 fitted
Euro cylinder change
Standard cylinder swap for the uPVC and composite resident doors across SE18 — measured flush, new keys, gone in under 30 minutes. The everyday move-in and end-of-tenancy job.
From £135 fitted
End-of-tenancy rekey
Every external lock you control changed before new tenants or owners move in — common around the General Gordon Square and Powis Street conversions. Fitting receipt with lock model and key count for landlord and deposit-protection records.
From £89 per door
Multipoint gearbox replacement
Ex-council or 1990s uPVC door dropped, or the handle lifts but won't throw the bolts? We carry Fuhr, Maco, GU, Yale and Lockmaster gearboxes on the van — swap just the failed gearbox instead of the whole door, after a proper gearbox-vs-cylinder diagnosis.
From £350 fitted
Broken key extraction
Snapped key in a cylinder or mortice — common after a basic builder's cylinder gives way. Non-destructive removal, lock re-tested, and a re-key or anti-snap upgrade if the barrel is worn or damaged.
From £120 fitted

I'm a leaseholder in one of the Royal Arsenal Riverside blocks and wanted the entrance door brought up to a TS007 3-star anti-snap cylinder. Instead of trying to sell me a whole new mechanism, they explained the multipoint was sealed and sound and only the cylinder needed upgrading. Swapped it, cut new keys, done in half an hour. Honest upgrade-not-replace advice.

We arrange a lot of end-of-tenancy lock changes near General Gordon Square and these are now the only locksmiths we use. Booked an end-of-tenancy change before new tenants moved in, every external lock done the same day, and the fitting receipt with lock model and key count was emailed straight over for the file. Fixed price, no fuss.

My Victorian terrace by Woolwich Common had a worn old 5-lever mortice that my insurer wasn't happy with. They fitted a BS3621 kitemark unit, lined it up perfectly in the old timber door, and gave me a receipt with the kitemark reference for the insurance file. Polite, tidy and fairly priced — exactly what I wanted.

Lock Change Woolwich — FAQs
Common questions from Woolwich leaseholders, landlords and homeowners.
Eight questions we hear week-in, week-out across SE18.
How much does it cost to change a lock in Woolwich?
Lock change in Woolwich starts from £89 for a basic external cylinder swap. A standard euro cylinder change is from £135, a BS3621 5-lever mortice for the older timber doors around Woolwich Common and General Gordon Square is from £180, a full lock replacement is from £189, and an anti-snap TS007 3★ cylinder upgrade — the usual job on a Royal Arsenal Riverside entrance door — is from £200. Fixed price first, no call-out fee.
I live in a Royal Arsenal Riverside flat — do I need a new lock or just a new cylinder?
On most Royal Arsenal Riverside composite and aluminium entrance doors the multipoint mechanism is sealed and sound, so the practical lock change is a euro-cylinder swap — usually to a TS007 3★ anti-snap cylinder — not a full mechanism replacement. We diagnose the door first and only change what needs changing. The cylinder upgrade is from £200 fitted with new keys.
Can you change the lock on my resident door, and what about the communal entrance?
We change the lock on your own resident flat door — that is yours to control. Communal entrance doors in Woolwich blocks usually run fob or access-control systems managed by the concierge or managing agent, so those changes go through building management rather than an individual resident. We will always tell you clearly which is which before any work.
What lock should I fit on an older terrace by Woolwich Common?
Older terraced and Victorian-conversion timber front doors around Woolwich Common, General Gordon Square and Woolwich New Road take a BS3621 5-lever mortice deadlock as the main lock (kitemarked for insurance) plus a quality nightlatch above. We fit BS3621 mortice from £180 and supply a fitting receipt with the kitemark reference for your insurer.
How much is an anti-snap cylinder upgrade in Woolwich?
An anti-snap upgrade is from £200 fitted — a TS007 3★ or SS312 Diamond cylinder (Ultion, Avocet ABS or Yale Platinum), new keys, removal of the old cylinder and any handle adjustment. It is the standard upgrade for new-build entrance doors at Royal Arsenal Riverside and for older builder's-spec cylinders across SE18, and it closes the most common forced-entry weakness on euro-cylinder doors.
Do you do end-of-tenancy lock changes for Woolwich landlords and letting agents?
Yes. Greenwich's private-rented licensing rules push managed-property landlords toward documented lock changes between tenancies, and end-of-tenancy rekeys are a regular Woolwich job for us. We provide a fitting receipt with the lock model, date and key count for landlord records, deposit-protection paperwork and licence files. From £89 per door, same-day across SE18, portfolio pricing available.
My uPVC or ex-council multipoint door has stopped locking smoothly — gearbox or cylinder?
On 1990s–2000s uPVC and older ex-council multipoint doors the failure is usually the gearbox (the handle lifts but won't throw the bolts) rather than the cylinder. We diagnose which it is on the door — a cylinder-only change is from £135, a gearbox replacement is from £350. Swapping the failed part beats replacing the whole door.
Do I need a BS3621 or TS007 lock for insurance in Woolwich?
Most UK home insurance policies require a BS3621 5-lever mortice deadlock on every final-exit timber door, or a multipoint system with a TS007 3★ (or SS312 Diamond) cylinder on uPVC and composite doors. We fit to those standards across SE18 and supply a fitting receipt with the kitemark or standard reference. See our insurance-approved door locks.
