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 £99 plus the hour band. The quote you approve on Cannon Street is the invoice. No hidden drill.
First: identify the suite. Floor, unit, landlord or occupier, and a callback number that matches the directory. In Cannon Street that is done against overbuild cores and roof-plant keys.
Next: open the door. Non-destructive first. Glass doors and patch locks need different tools to timber. In Cannon Street that is done against overbuild cores and roof-plant keys.
Finally: leave it usable. A key, a recode, or a temporary cylinder until facilities order the specified ironmongery. In Cannon Street that is done against overbuild cores and roof-plant keys.
Standards we actually name on invoices from this patch include BS 3621. 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.

constraint
narrow Dowgate Hill is the Cannon Street version of "the van is close". We walk kits. Bollards, coaches and the ring of steel are normal.
Typical local job: Walbrook glass patch locks. Typical local housing or occupier mix: limited upper-floor residential.
Stations staff mention on the call: Cannon Street, Mansion House, Monument. They are not parking. They are how we know which court you mean.
grid
From Cannon Street we also write this service against Office lockout in Monument, Office lockout in Bank, Office lockout in Cheapside, Office lockout in Blackfriars.
Other jobs we actually do on this patch: Emergency locksmith in Cannon Street, Commercial locksmith in Cannon Street, Access control in Cannon Street.
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 Cannon Street, Cannon Street, the floor, the door type if you know it (overbuild cores), and who has the right to enter. Say whether security is on a desk. Say whether it is Friday 18:30 last-one-out.
Do not say "near Monument" 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 Office Lockout or a sibling service. Getting the noun right is how you get the right bag out of the van.
after
You should leave with a working key or a reset, a written figure, and a note of the stamp on older ovals in lanes. 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.

Occupiers who hold a Cannon Street door often hold another in Monument. We can chart those on a master key visit rather than as three panics.

stock
lane remnants dominates the Cannon Street mix. That is why office furniture locks shows up on this job more often than a suburban nightlatch. We keep override keys on the van because roof padlatch seizures is not a rare event here.
If the job is a roof, say how you reach it: which lift, which hatch, which pass. That is the time, not the picking. If you only say "Cannon Street" we will still come; if you say Cannon Street and the intercom number we will stand in the right court.
Heritage or campus rules on this patch: Roof plant after midnight needs a named escort or a working pass. We do not wander a silent overbuild. Related openings live on locksmith work in Cannon Street and on areas covered.
night
Station last trains; then a hard quiet on Dowgate; rooftop plant still hums.
Timing band for this service: Friday 18:30 last-one-out. This is first-ring from London Street, still subject to the constraint on the kerb.
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.
open
Cannon Street calls for office lockout tend to start on Cannon Street or College Hill, not on a generic London map pin. The working landmark is Dowgate. The working station is Monument. CITY OF LONDON LOCKSMITH1 LTD dispatches from EC3R and treats this as a Square Mile run, with narrow Dowgate Hill already priced into how long the last hundred metres take.
The door in front of you is likely overbuild cores. The ironmongery is likely older ovals in lanes. The failure that got you here is often a contractor cylinder left after a fit-out and never recorded. 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 Cannon Street is not enough.
Non-destructive entry is the default on this patch, as it is on office lockout 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.
Call the EC3 yard. We quote at the door after we see the lock.
