method
First: measure. Cylinder length, cam, offset, and the door thickness before we pull the old lock. In Cheapside that is done against aluminium shopfronts and office speed gates.
Next: match the grade. Insurance and door type decide BS 3621, TS007, or a commercial oval. In Cheapside that is done against aluminium shopfronts and office speed gates.
Finally: fit and hand keys. Operation tested, old keys destroyed on request, receipt left. In Cheapside that is done against aluminium shopfronts and office speed gates.
Standards we actually name on invoices from this patch include PAS 24. 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.
after
You should leave with a working key or a reset, a written figure, and a note of the stamp on multipoint retail. 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.

hardware
Cheapside doors in our notes: aluminium shopfronts; timber civic inner doors; office glass above. Cylinders and cases: multipoint retail; civic mortices; office euros. Access control around them: staff-only retail doors; civic readers; office speed gates.
For lock change and repair we additionally carry TS007 3-star cylinders, BS 3621 cases, multipoint gearboxes. Failure modes that match this pair: worn plug; snapped cam.
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.
constraint
pedestrianisation hours is the Cheapside version of "the van is close". We walk kits. Bollards, coaches and the ring of steel are normal.
Typical local job: retail staff-door maglocks. Typical local housing or occupier mix: upper-floor flats over shops.
Stations staff mention on the call: Mansion House, St Paul's, Bank. They are not parking. They are how we know which court you mean.
open
Cheapside calls for lock change and repair tend to start on Bow Lane or King Street, not on a generic London map pin. The working landmark is Bow Bells. The working station is St Paul's. CITY OF LONDON LOCKSMITH1 LTD dispatches from EC3R and treats this as a Square Mile run, with pedestrianisation hours already priced into how long the last hundred metres take.
The door in front of you is likely aluminium shopfronts. The ironmongery is likely multipoint retail. The failure that got you here is often worn plug. 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 Cheapside is not enough.
Non-destructive entry is the default on this patch, as it is on lock change and repair 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.
standards
We write BS 3621, TS007, PAS 24, BS EN 1303 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 £85 plus the hour band. The quote you approve on Bow Lane is the invoice. No hidden drill.
stock
office cores above shops dominates the Cheapside mix. That is why multipoint gearboxes shows up on this job more often than a suburban nightlatch. We keep cylinders on the van because shutter cylinders is not a rare event here.
If you are retail, tell us shutter or inner staff door. If you are offices above, tell us the stair the building actually uses after 19:00. If you only say "Cheapside" we will still come; if you say Bow Lane and the intercom number we will stand in the right court.
Heritage or campus rules on this patch: Retail lockouts after closing need the manager, not a colleague with a story. Related openings live on locksmith work in Cheapside and on areas covered.
voice
Say Cheapside, Bow Lane, the floor, the door type if you know it (aluminium shopfronts), and who has the right to enter. Say whether security is on a desk. Say whether it is same-day City changes.
Do not say "near St Paul's" 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 Lock Change and Repair or a sibling service. Getting the noun right is how you get the right bag out of the van.
Call the EC3 yard. We quote at the door after we see the lock.
