Keys lost away from home
Consider whether the keys carry an address, distinctive fob or other information linking them to the property. Urgency follows the credible access risk, not the neighbourhood name.
Keys · authority · handover · accountable access
A missing key, a house move or a change of tenant is first a key-control question. Before choosing hardware, establish which door is affected, who can authorise a change and which people should still have access afterwards.

Key-control decisions
Lock replacement is not simply an exchange of one metal part for another. It changes who can use the entrance, how many keys exist and who is responsible for future copies. In a Highbury family house, that may mean accounting for relatives, cleaners or a previous owner. In a converted flat, the private front door can sit behind a communal entrance that one resident cannot alter alone. A rented home adds the terms of the tenancy and the landlord’s responsibility for approved changes.
Write down the desired outcome before booking. If the aim is to exclude an unknown key, say so. If the existing lock is difficult but all keys are accounted for, repair or adjustment may be the better question. If several doors use different keys, decide whether the enquiry is about convenience, security, or both. The locksmith can then assess compatible options without promising that every entrance can or should be keyed alike.
Consider whether the keys carry an address, distinctive fob or other information linking them to the property. Urgency follows the credible access risk, not the neighbourhood name.
Explain what was taken and whether the address can be inferred. If theft or another crime is involved, follow police guidance and keep any reference needed for records.
List front, rear, side, garage and garden doors. Unknown duplicate keys may justify a planned change, while hardware selection still depends on each door.
The authorised party should decide the new key issue, access for the tenant and any retained management keys. Do not assume a housemate can approve alterations for the whole property.
If key control remains sound, ask for the operating fault to be assessed. A stiff key or poor latch can involve the door, frame or connected hardware.
A common front door belongs within the building’s management arrangements. One flat’s inconvenience does not by itself authorise a lock or access-control change.
Problem and next step
| Situation | Useful information | Sensible next step |
|---|---|---|
| One key cannot be found | Last known place, identifying tags, remaining copies and who needs entry | Assess the likelihood of unauthorised access before agreeing a change |
| Keys and address details were stolen | Doors served, police or insurer requirements and current occupancy | Discuss prompt restoration of trustworthy key control |
| New owner has received several keys | Complete door list, operation of each lock and keys handed over | Audit entrances, then specify only the changes that meet the desired outcome |
| Tenant or housemate has moved out | Tenancy authority, returned keys and doors within the proposed scope | Obtain the property decision-maker’s approval before altering hardware |
| Key is present but will not turn | Door open or closed, spare-key result and whether pressure changes operation | Stop forcing it and request fault assessment rather than assuming replacement |
Authority before access
Entry and lock changes affect possession and security. Prepare evidence showing your occupancy, ownership or management authority. If identification is locked inside, explain that during the first call so a suitable verification route can be discussed. A contractor collecting keys for somebody else should have a named contact who can confirm the instruction.
Authority may stop at the private front door. A freeholder or managing agent can control the communal entrance, meter room or common gate. A landlord may also set requirements for hardware fitted to a rented door. These boundaries are practical safeguards, not administrative extras. They prevent one person’s request from changing access for others who have rights in the building.

Highbury property context
Highbury includes period houses used as single homes, houses divided into flats, purpose-built accommodation and rented properties with more than one authorised occupant. The building type does not determine which lock is fitted, but it does change the questions to ask before a key-control change. A family house may have several exterior doors. A converted property can combine a communal street door with private flat entrances. In a managed block, the apartment lock and common access system can have different owners and contractors.
| Property situation | Confirm before booking | Why it changes the scope |
|---|---|---|
| Period family house | Front, rear, side and garden entrances plus current key holders | The key-control outcome may need more than the most visible lock |
| House converted into flats | Private flat door, shared front door and the party responsible for each | One resident may authorise only the door within their control |
| Rented flat or shared house | Tenant instruction, landlord consent and access needed by other occupants | The new key issue must preserve agreed rights of entry |
| Purpose-built managed block | Concierge or agent procedure and whether the common entrance is mechanical or electronic | Apartment hardware and building access may require separate services |

Hardware selection
A request for “new keys” can be met in different ways depending on the existing lock and desired result. Some hardware may allow a cylinder or another component to be changed while serviceable parts remain. Other doors use mortice, rim or multipoint arrangements that require different measurements and checks. A photograph of the key is not enough to specify a part.
Provide full-door photographs, both faces of the handle or lock, the door edge and the frame keeps. State the door material and whether the difficulty appears with the door open, closed or both. The locksmith can then consider compatibility, existing holes, case dimensions, handing, required security characteristics and key quantities. Where a door is also misaligned or damaged, lock work and door repair should be separated in the quotation.
Agree how many keys are included, who will receive them and whether extra authorised users need copies. Count the keys after fitting and record any restrictions on duplication that the chosen system genuinely carries. Do not describe a key as controlled, restricted or high security unless its actual product documentation supports that description.
Scope and quotation
A neighbourhood name cannot establish a reliable price. The work depends on the lock, door, access, timing, selected parts and whether opening, repair or making good is also required. Ask for a quote that identifies the outcome and its boundaries.
| Requested outcome | Scope to make explicit | Factors that remain to be assessed |
|---|---|---|
| Restore entry after keys are unavailable | Attendance, verification, opening method and any follow-on securing | Door state, lock condition and whether a replacement becomes necessary |
| Regain trusted key control | Named doors, agreed hardware, fitting and number of supplied keys | Compatibility, measurements, access and condition of connected parts |
| Repair a difficult lock | Assessment, adjustment or component work within an agreed limit | Door alignment, wear, internal fault and part availability |
| Change several entrance locks | Door schedule and a separate specification for each opening | Whether compatible keying options meet the required security outcome |
| Address a communal entrance | Management authority and mechanical or electronic system boundary | Fire-door duties, access-control responsibility and other specialist work |
Confirm whether the quote covers successful opening, replacement hardware, additional keys, disposal of old parts and any surface repair. If inspection changes the proposed work, the reason and revised scope should be approved before it proceeds.
A practical handover
State whether this is a loss, theft, move, tenancy change or operating fault. That keeps the security decision tied to a real need.
List residents, owners, managers and any service user who should retain entry after the work.
Confirm which entrances are included and which common or neighbouring doors are outside the instruction.
Test normal operation, count supplied keys and note any unresolved frame or management issue.
Keep invoices, product information and the new key issue with the property records. Avoid labelling keys with the full address. If another person later receives a copy, update the access record rather than relying on memory.
Highbury locksmith FAQ
Not automatically. Consider whether the key can be linked to the address, whether another authorised copy exists and how credible unauthorised access is. A locksmith can then assess the door and discuss a proportionate option.
Explain what was taken, which doors the keys serve and who remains inside the property. Follow police or insurer instructions where relevant and arrange a key-control decision without trying to alter the lock yourself.
A tenant can report the concern and arrange lawful access, but the tenancy and landlord’s authority determine who can approve an alteration and who must receive keys. Clarify this before parts are fitted.
Review whether all keys are accounted for, which entrances exist and whether the hardware works properly. Replacement may be a sensible way to establish known key control, but it is not a rule that every lock must change.
That depends on the actual lock families, dimensions and security objective. Ask for compatibility to be assessed rather than assuming unrelated front, rear and garden hardware can share a key.
The freeholder, managing agent or other responsible building party normally needs to decide. The entrance may also involve fire-door or electronic access responsibilities beyond an individual resident’s instruction.
Have reasonable evidence of occupancy, ownership or management authority. If identification is inside, mention that during booking so the locksmith can explain an appropriate verification process.
Do not assume a quantity. Agree the supplied number, any genuine copying restrictions and the cost or route for authorised extras before accepting the hardware specification.
Check closing, latching, locking and unlocking from the authorised sides of the door. Count the keys and record any frame, hinge, closer or communal-access concern left outside the locksmith scope.
