You should leave with a working key or a reset, a written figure, and a note of the stamp on mortices on older walk-ups. 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 Aldgate door often hold another in Tower Hill. We can chart those on a master key visit rather than as three panics.

voice
Say Aldgate, Houndsditch, the floor, the door type if you know it (timber walk-ups), 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 Tower Gateway" 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.
law
The City boundary with Tower Hamlets runs through this edge. We still need the right door, not the right borough slogan.
We record who instructed the open. Neighbouring suites in retail on the high street look identical after midnight. Aldgate Square 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 Houndsditch. That is slower than a cowboy and cheaper than a complaint.
open
Aldgate calls for lock change and repair tend to start on Houndsditch or Houndsditch, not on a generic London map pin. The working landmark is Aldgate Square. The working station is Tower Gateway. CITY OF LONDON LOCKSMITH1 LTD dispatches from EC3R and treats this as a Square Mile run, with Aldgate gyratory remnants already priced into how long the last hundred metres take.
The door in front of you is likely timber walk-ups. The ironmongery is likely mortices on older walk-ups. The failure that got you here is often gearbox teeth gone. 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 Aldgate 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.
stock
retail on the high street dominates the Aldgate mix. That is why multipoint gearboxes shows up on this job more often than a suburban nightlatch. We keep mortice cases on the van because uPVC and aluminium lockouts is not a rare event here.
If your intercom says E1, say so. We still attend. The invoice does not care about the City crest; the door does care about the lock family. If you only say "Aldgate" we will still come; if you say Houndsditch and the intercom number we will stand in the right court.
Heritage or campus rules on this patch: The City boundary with Tower Hamlets runs through this edge. We still need the right door, not the right borough slogan. Related openings live on locksmith work in Aldgate and on areas covered.
hardware
Aldgate doors in our notes: aluminium retail; timber walk-ups; new residential multipoints. Cylinders and cases: multipoint gearboxes; euro street cylinders; mortices on older walk-ups. Access control around them: video entry on residential cores; shop night latches; office readers.
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.
night
High street stays later than Bank; Minories quietens; residential cores get the late calls.
Timing band for this service: same-day City changes. 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.
method
First: measure. Cylinder length, cam, offset, and the door thickness before we pull the old lock. In Aldgate that is done against timber walk-ups and shop night latches.
Next: match the grade. Insurance and door type decide BS 3621, TS007, or a commercial oval. In Aldgate that is done against timber walk-ups and shop night latches.
Finally: fit and hand keys. Operation tested, old keys destroyed on request, receipt left. In Aldgate that is done against timber walk-ups and shop night latches.
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.
constraint
Aldgate gyratory remnants is the Aldgate version of "the van is close". We walk kits. Bollards, coaches and the ring of steel are normal.
Typical local job: shop shutter cylinders. Typical local housing or occupier mix: new residential around Aldgate Square; older walk-ups toward Portsoken.
Stations staff mention on the call: Aldgate, Aldgate East, Tower Gateway. They are not parking. They are how we know which court you mean.
Call the EC3 yard. We quote at the door after we see the lock.
