There’s rarely a “typical” callout, but this is what keeps our vans busy around Eton Avenue, Winchester Road, Avenue Road and the streets backing onto Finchley Road:
Lock replacement on front, back and internal entrances: old cylinder out, new one in, one visit
Locks repair for anything sticking, grinding or refusing to turn
New locks supply and fitting, including the latest British Standard locks (BS3621)
Multi-point locking systems for UPVC doors and composite sets (we genuinely specialise in these as a true UPVC specialist, not just a jack of all trades)
Emergency lockout callouts day or night, doors opened without damage wherever possible
After-burglary repairs: putting frames, glazing and hardware back together and secure following a break-in
Opening safes where the code has been lost or gone astray
Fire doors: we can supply, checks and basic compliance work
Mail box locks for blocks of flats
Bike locks: we can open all types of bike locks
Security locks upgrades for older windows and tired UPVC frames
Retail and shopfront locksmith work for the independent businesses along Finchley Road (where the big retail chains send whoever’s free, we know these streets)
If your job isn’t on that list, ask anyway. We offer many more services than we can print here, and most vans carry the stock to sort things the same visit rather than booking a return trip.
There’s no “out of hours” surcharge mentality here. Our emergency locksmith services run right through the night, and daytime jobs get exactly the same treatment. Bad weather, a bank holiday, 2am on a weeknight (an emergency locksmith callout in Swiss Cottage gets handled the same, whatever the clock says). Ring us, say where you are and what’s happened, and you’ll get a straight answer on timing before you commit to anything. In the small hours, our night cover has NW3 sorted too.
Our nearest base sits just off Marylebone Road, a short run down to NW3, so in quieter periods you’re looking at a 15–20 minute response. We are among the faster response times in North West London. When several jobs land at once, that response time stretches a little; we’d rather be upfront than promise what we can’t deliver.
NW Locksmith came together when two older, well-established London locksmith firms merged — so the Swiss Cottage skilled locksmiths turning up at your property aren’t fresh out of a two-week course. Between them, our professional locksmiths have fitted and replaced more locks across NW3 than we could list: awkward rim locks in Victorian mansion blocks, composite multi-point systems in the developments by the station, and everything in between.
Where the big national franchises rotate staff between postcodes, we’ve stayed independent and local. Locks change over the decades, and insurer-approved locks change almost yearly too. So, alongside the old-school knowledge, our Swiss Cottage locksmiths keep the vans stocked with modern tools, and the hardware manufacturers recommend this year, not five years ago.
Whatever the security requirement, our insured technicians arrive equipped to finish the job on the first visit rather than sending you off to source parts yourself: from a straightforward lock installation to a full multi-point overhaul. Coverage runs across Swiss Cottage, Finchley Road, Eton Avenue, Avenue Road and the area immediately around the tube. If a job sits just outside that patch, we’ll usually still come. Homes, business premises, HMOs and rental property all get the same services and the same pricing, and every installation is logged for the warranty.

For more of these, check @nwlocksmith_uk on Instagram and Facebook, or the blog, where we write up the more interesting jobs — being on call around here is simply part of Swiss Cottage living for this team.
Every lock we install carries a full year’s warranty. Just email a photo of the fitted lock once the job’s done, and we’ll log it against your job number. All work carried out is covered: if anything’s not right with the workmanship inside that year, we come back and sort it. Keeping your property secure is the whole point of the job, so we stand behind it.
We’re also straightforward on price. A technician assesses the lock on site, talks you through the realistic options and quotes before touching anything, no surprise invoice at the end. Jobs typically start from £45, with the full breakdown on our pricing page.


Returning clients get 10% off the next callout. Just mention your previous invoice (name and address matching) when you ring.
