Same-day lock change & upgrade across all of Croydon — front-door BS3621 mortice, anti-snap euro cylinders, uPVC multipoint repairs, after-move lock-outs and tenancy hand-overs. Croydon-based engineer on the van with Ultion, Avocet ABS, Yale and Yale-fit gearboxes. Book a slot or get a fixed price first.
Croydon's housing stock is genuinely mixed and we change locks across every kind of door here. Victorian and Edwardian terraces through Broad Green, Selhurst, Park Hill, South Croydon and Addiscombe still use original timber doors that want a proper 5-lever BS3621 mortice deadlock alongside a nightlatch — most domestic insurance policies require the kitemark, and we fit and certify them from £180.
Out in Shirley, Forestdale, Coombe, Waddon and the New Addington estates, you're more likely to have a 1980s–2010s uPVC or composite front door running a euro cylinder inside a multipoint gearbox. That's our most common job in Croydon — straight cylinder swaps from £135, anti-snap SS312 Diamond upgrades from £200, or a full multipoint mechanism replacement when the handle drops, the door won't lift, or the gearbox has seized.
And in the high-rise belt around East Croydon — Saffron Square, the Wellesley Road towers, and the new Boxpark/Whitgift quarter — most flat entrance doors are euro-cylinder fire doors. We stock Ultion, Avocet ABS, Yale Platinum and Mila cylinders on the van and finish a typical CR0 flat lock change in under 30 minutes.
Whether you've just moved into a Croydon property, finished a tenancy, lost your keys, want to upgrade to anti-snap cylinders, or just need a stuck lock made workable again — book a same-day slot or pre-book a time that suits you. From £89 fitted, fixed price first, no call-out fee.
Every Croydon visit follows the same routine: a Croydon-based engineer rolls up, gives you a fixed price first, then fits the right lock for your door type and insurance grade. No call-out fee, no hourly drift, no upsell.
Insurance-grade 5-lever mortice deadlock for timber front and back doors across South Croydon, Park Hill, Selhurst and the rest of the Victorian terraced stock. Kitemark-stamped and supplied with a fitting receipt for your insurer.
From £180 fittedThe standard uPVC and composite door lock swap — front cylinder out, new keys in. We measure the cylinder before fitting so it sits flush, never proud — proud cylinders are exactly what snap attacks target. New keys included.
From £135 fittedSS312 Diamond or TS007 3★ rated cylinders — Ultion, Avocet ABS, Yale Platinum. Drops a snap-attempt locking pin into place and stops snap-attacks dead — the most common UK MO. Recommended for every uPVC/composite door in Croydon.
From £200 fitteduPVC door dropped, handle floppy, key won't turn fully? We carry replacement Fuhr, Maco, GU, Yale, Lockmaster and Avocet WMS gearboxes on the van — full strip-and-replace usually in a single visit across CR0.
From £350 fittedCroydon has one of London's largest HMO licensing zones. We do same-day full-property re-keys for new owners, landlords and letting agents — every external door changed, deposit-protection paperwork-ready receipt with model and key count.

Same engineer, same van — but the lock we fit changes depending on whether it's a Park Hill timber front door, a Shirley uPVC backdoor, or a Saffron Square flat entrance. Here's what we typically stock for each.
Broad Green, Selhurst, South Croydon, Addiscombe, Park Hill — most original front doors are timber with a 5-lever mortice deadlock + nightlatch combo. We fit BS3621 kitemarked mortice for insurance compliance plus a quality nightlatch above.
New Addington, Waddon, Whitehorse and the older Shirley estates — euro cylinder inside a multipoint strip. Lock-snapping is the dominant attack on these — every Croydon uPVC door we touch gets an anti-snap upgrade quote even if the original swap was basic.
Glass-reinforced composite doors are now standard on Croydon's 1990s–2020s housing stock. Inside they run the same multipoint strip as uPVC. We routinely upgrade to Sold Secure Diamond anti-snap cylinders and check the gearbox tolerance while we're there.
Communal-corridor fire doors on flats around Wellesley Road, Saffron Square and the new Boxpark/East Croydon developments. Fire-rated euro cylinders, anti-pick pinning, restricted profiles if you want one key cut policy. Most jobs done in under 30 minutes.
We've been running a Croydon-based engineer van out of CR0 since 2015 — that's 10+ years of changing locks on the same Victorian terraces, uPVC semis and East Croydon flats over and over. We know the door types, the brand fits, and the insurance grades before you've finished your sentence.
No call-out fee, no surprise charges, no upsell. You get a fixed price first, a fitting receipt with the lock model after, and a 12-month workmanship warranty as standard.

From Old Town and East Croydon across to Shirley, Selhurst and out to New Addington — one engineer, one number, the whole CR0 footprint.
Three recent CR0 jobs in three different sub-areas. Every review is from a verified Google customer.
We bought a Victorian terrace off Park Hill Road and wanted every external lock changed on completion day. They came back with a quote in 20 minutes, fitted a Union BS3621 plus a Yale 89 on the front and the same on the back — finished by lunchtime. Paperwork went straight to our insurer.
My Saffron Square flat had the basic builder's cylinder — the engineer measured it, popped in a Yale Platinum 3-star, and even nudged the handle screws back square. Whole job in 25 minutes, fixed price as quoted, professional ID-badged engineer. I'm sleeping easier knowing snap attacks won't get through.
uPVC back door on our Fieldway estate flat dropped a couple of inches and the key wouldn't lift the handle anymore. Two other firms wanted to replace the entire door. These guys swapped out just the Fuhr gearbox, realigned the keeps, and we're back to one-finger locking. Saved us a small fortune.
