From Smithfield we also write this service against Master key systems in Barbican, Master key systems in St Paul's, Master key systems in EC1, Master key systems in Islington.
Other jobs we actually do on this patch: Commercial locksmith in Smithfield, Lock change in Smithfield, Office lockout in Smithfield.
The full service list and area list exist so search engines and facilities teams land on a street, not a blob called London.
Say Smithfield, Cloth Fair, the floor, the door type if you know it (market steel), 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 Barbican" 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.

hardware
Smithfield doors in our notes: market steel; heritage timber; clinical back-of-house. Cylinders and cases: heavy padlatches; period mortices; modern euros on infill. Access control around them: market trader doors; hospital-adjacent restricted; restaurant night latches.
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.
standards
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 Cloth Fair is the invoice. No hidden drill.
after
You should leave with a working key or a reset, a written figure, and a note of the stamp on heavy padlatches. Old keys can be destroyed on request.
If staff still share one key between a floor, master key systems is the planned conversation. If the closer slammed the latch, the closer is part of the job, not a mystery for next week.

open
Smithfield calls for master key systems tend to start on Cloth Fair or Long Lane, not on a generic London map pin. The working landmark is Smithfield Market. The working station is Barbican. CITY OF LONDON LOCKSMITH1 LTD dispatches from EC3R and treats this as a Square Mile run, with hospital access rules already priced into how long the last hundred metres take.
The door in front of you is likely market steel. The ironmongery is likely heavy padlatches. The failure that got you here is often everyone on the grand master. 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 Smithfield 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.
law
Hospital and market occupiers are not interchangeable. We match the door to the organisation.
We record who instructed the open. Neighbouring suites in hospital-adjacent fabric look identical after midnight. Smithfield Market 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 Long Lane. That is slower than a cowboy and cheaper than a complaint.
stock
hospital-adjacent fabric dominates the Smithfield mix. That is why construction-key systems shows up on this job more often than a suburban nightlatch. We keep key tags on the van because pre-dawn market cylinders is not a rare event here.
If you are on market time, say the hour you need the door working, not only where you are now. If you only say "Smithfield" we will still come; if you say Cloth Fair and the intercom number we will stand in the right court.
Heritage or campus rules on this patch: Hospital and market occupiers are not interchangeable. We match the door to the organisation. Related openings live on locksmith work in Smithfield and on areas covered.
constraint
hospital access rules is the Smithfield version of "the van is close". We walk kits. Bollards, coaches and the ring of steel are normal.
Typical local job: heritage repairs. Typical local housing or occupier mix: Cloth Fair houses; modern flats on Long Lane.
Stations staff mention on the call: Farringdon, Barbican, St Paul's. They are not parking. They are how we know which court you mean.
portfolio
Occupiers who hold a Smithfield door often hold another in Barbican. We can chart those on a master key visit rather than as three panics.
