Master key systemsfrom £180
Jewellery workshops have their own habits. We still need ownership proof, especially on safes.
We record who instructed the open. Neighbouring suites in Holborn offices look identical after midnight. British Museum edge is a meeting point, not a proof of tenancy.
CITY OF LONDON LOCKSMITH1 LTD will wait for ID rather than rush a wrong door on Euston Road. That is slower than a cowboy and cheaper than a complaint.
We write BS EN 1303, TS007, BS 3621 when we have fitted or tested them. A "high security" unbranded barrel bought to look the part is how the next attacker gets in.
Insurance language in the Square Mile and its neighbours still leans on BS 3621 for certain final exits and TS007 for replacement euros. If your schedule says otherwise, send it.
From-price for this service starts at £180 plus the hour band. The quote you approve on Euston Road is the invoice. No hidden drill.

The full service list and area list exist so search engines and facilities teams land on a street, not a blob called London.
voice
Say Camden, Euston Road, the floor, the door type if you know it (office timber), and who has the right to enter. Say whether security is on a desk. Say whether it is survey then manufacture.
Do not say "near King's Cross" as the only address. Do say the intercom label. Do send a forend photo if the street is quiet enough.
We will tell you if the job is actually Master Key Systems or a sibling service. Getting the noun right is how you get the right bag out of the van.
open
Camden calls for master key systems tend to start on Euston Road or Euston Road, not on a generic London map pin. The working landmark is British Museum edge. The working station is King's Cross. CITY OF LONDON LOCKSMITH1 LTD dispatches from EC3R and treats this as a neighbouring borough run, with Holborn bus lattice already priced into how long the last hundred metres take.
The door in front of you is likely office timber. The ironmongery is likely office euros. The failure that got you here is often unlabelled jam-jar keys. We confirm lawful access before a pick enters the keyway: occupier, director, nominated facilities lead, or written authority from the agent. A name on a doorbell in Camden is not enough.
Non-destructive entry is the default on this patch, as it is on master key systems city-wide. Drilling is a named decision on the pavement. Read price bands if you can; night and Sunday supplements are written, not invented after the door is open.
stock
Holborn offices dominates the Camden mix. That is why suite cylinders shows up on this job more often than a suburban nightlatch. We keep restricted cylinders on the van because workshop lockouts is not a rare event here.
Hatton Garden shutters are a trader-plus-authority job. Do not send an apprentice with a story. If you only say "Camden" we will still come; if you say Euston Road and the intercom number we will stand in the right court.
Heritage or campus rules on this patch: Jewellery workshops have their own habits. We still need ownership proof, especially on safes. Related openings live on locksmith work in Camden and on areas covered.
night
Holborn empties; King's Cross never does; Hatton Garden shuts hard.
Timing band for this service: survey then manufacture. This is a neighbouring-borough clock from EC3, quoted honestly, not a Monument-speed fantasy.
WhatsApp +44 7895 673226 accepts a photo of the forend if you are safe to take one. The phone remains 020 3371 1246. Company number 11001390 sits on the invoice.
constraint
Holborn bus lattice is the Camden version of "the van is close". We walk kits. Borough parking and estate barriers are normal.
Typical local job: workshop lockouts. Typical local housing or occupier mix: mansion blocks; railway-fringe new-build.
Stations staff mention on the call: Holborn, Euston, King's Cross, Chancery Lane. They are not parking. They are how we know which court you mean.
hardware
Camden doors in our notes: workshop steel; office timber; mansion blocks. Cylinders and cases: high-security workshop; office euros; period mortices. Access control around them: workshop buzzers; office readers; mansion video.
For master key systems we additionally carry restricted euro profiles, suite cylinders, construction-key systems. Failure modes that match this pair: unlabelled jam-jar keys; everyone on the grand master.
If the reader is the failure rather than the cylinder, pivot to access control. If the opening is damaged, pivot to burglary repair. If you simply need the suite open, office lockout may be the tighter description.
method
First: chart the doors. Every opening, who needs it, and who must never have it. In Camden that is done against office timber and workshop buzzers.
Next: cut the hierarchy. Sub-masters, housekeeper keys, and a tightly held grand master. In Camden that is done against office timber and workshop buzzers.
Finally: stamp and issue. Cylinders stamped, keys counted, extras held or destroyed. In Camden that is done against office timber and workshop buzzers.
Standards we actually name on invoices from this patch include TS007. We do not print a kitemark we did not fit. If your insurance schedule is tighter than the barrel in the door, that becomes a lock change on the same visit if you want it quoted as a separate line.
Call the EC3 yard. We quote at the door after we see the lock.
