Private key-control change
Compatible hardware and recipient quantities are set by the new owner.
Completion inventory · key provenance · managed boundary · new-owner handover
An ownership change can bring keys from sellers, agents, relatives, cleaners and building management. A Finchley completion inventory should show where each key came from and which entrance it operates before the new owner changes access.

Key provenance inventory
Group keys by the person or organisation that supplied them, then test them at relevant doors through normal authorised use. Label uncertain keys and stop at resistance. Do not photograph detailed cuts for a widely shared record.
The inventory cannot prove that no other copy exists. It can show which keys the new owner controls and which systems belong to management. That evidence supports a proportionate choice instead of a blanket instruction to replace everything.
| Key source | Door or system to confirm | New-owner decision |
|---|---|---|
| Seller handover | Private front, rear and internal security doors | Retain known access or plan a key-control change |
| Estate or conveyancing agent | Keys held for viewing or completion | Account for return without assuming exclusivity |
| Managing agent | Communal entrance, garage or controlled store | Follow building issue and copying process |
| Family or household contact | Spare private keys | Decide future authorised recipients |
| Unknown or unlabelled set | Safe authorised identification | Retain, relabel or dispose after purpose is confirmed |
Separate control from condition
A stiff lock, loose handle or door that misses the frame should be recorded independently. Changing a cylinder for key control does not repair a worn mechanism or alignment issue. Conversely, a sound repair does not invalidate unknown old keys.
Photograph the doors and list current operation. In a managed flat, ask which hardware belongs to the dwelling and which remains communal. In a converted house, confirm whether the original street door serves several owners.

Inventory to action
| Finding | Question | Possible route |
|---|---|---|
| All supplied private keys are accounted for | Does the owner accept the known history? | Retain, repair or make a planned change |
| Old private copies cannot be accounted for | Which doors and future users are affected? | Targeted owner-approved lock or cylinder change |
| Communal key history is uncertain | Who manages the building system? | Refer to management; do not alter alone |
| Garage key is missing | Is the garage private, shared or powered? | Correct owner and mechanical or specialist route |
| Private lock is mechanically unreliable | What fails open and closed? | Repair assessment separate from key control |
| Key breaks during identification | Where is the fragment and is the door secure? | Extraction and later access decision |
New-owner service choices
Compatible hardware and recipient quantities are set by the new owner.
Door, lock and frame condition guide repair independently of key history.
Ownership evidence and door state support an authorised method.
Fragments are removed before retained lock condition is assessed.
Building management controls shared keys and entrances.
Garage, gate and store doors require confirmed ownership and users.
Quotation and completion file
Finchley does not determine a standard locksmith price. The actual entrance, method, labour, parts and key count shape the proposal.
| Line | Input | Completion file |
|---|---|---|
| Door schedule | Private, shared and outbuilding entrances | Included and excluded doors |
| Key-control change | Old-key concern and authorised users | New hardware and old-key effect |
| Repair | Mechanical symptom and diagnosis | Work and operational test |
| Keys | Owner, family and agent quantities | Copies by named recipient |
| Management interface | Communal rules and building contact | Shared systems left or changed under authority |
| Making good | Door and finish condition | Locksmith and other-trade boundary |
Hidden damage or a different lock preparation should trigger a revised owner decision. Completion pressure is not permission for undefined work.

Finchley property context
A family house may include front, rear, garage and garden-room keys. Confirm which spaces transfer and list each door independently.
A converted property can have a communal front key plus private dwelling keys. A managed flat may add fobs or controlled garage access. These remain under the building’s issuing process.
Property type does not prove that a lock should change. The new owner’s control objective and present hardware condition support the decision.
Ownership handover
Test every changed or repaired door, count keys and label recipient sets. Record communal credentials separately and avoid storing sensitive key detail in open documents.
Add exclusions, inaccessible doors and other-trade repairs. The completion file should state what is known without claiming that no historical copy exists.
Finchley ownership-change FAQ
No. It records the supplied set but cannot prove the complete historical copying record.
Only gently by the authorised owner at relevant doors. Stop at resistance and label uncertainty.
Only through the freeholder or managing agent responsible for all users.
Record their return and door purpose. Their possession history is one part of the inventory.
Yes when ownership, access and whether the system is mechanical are confirmed.
Not unless the cylinder is the diagnosed issue. Mechanism and alignment require separate assessment.
The new owner supplies a named recipient list and agreed quantities.
Keep the door schedule, hardware work, key issue, shared-system notes, tests and exclusions.
Record provenance without overclaiming certainty
Send the Finchley address, received key groups, included doors, current faults and authorised owner contact.
The completion-day key ledger
A handover bundle may contain several keys that look alike, keys with no confirmed door, and copies mentioned by an earlier occupier but not returned. Do not test an unidentified key through every lock. Start a ledger using neutral labels such as main private door, rear door, garage pedestrian door and communal lobby. Record who supplied each item and whether its function was safely verified.
Separate possession from provenance. A key being present does not prove it is the only copy, and a missing key does not prove misuse. The practical decision is which authorised people need access from completion onward and which lock boundaries require a change to meet that plan. This avoids unsupported claims about previous owners, tenants, agents or contractors.
In managed flats, the communal entrance may use a key or credential controlled by the freeholder or managing agent. The incoming owner can catalogue what was received, but should not alter shared hardware without authority. Keep the private-flat key decision in its own section so communal restrictions do not delay a clearly authorised private-door assessment.
Family houses and conversions often have more than one external door. Walk the property with the authorised owner, name each entrance and list whether it is included, excluded or inaccessible. Outbuildings and internal cupboard keys can be recorded for the owner without being represented as locksmith-tested unless that work was requested.
After approved replacement or rekeying, count every supplied key in front of the recipient. Record any retained locks and keys that still operate elsewhere. Destroying or disposing of old keys is an ownership decision and should follow the agreed secure process; do not leave unidentified keys loose at the property.
The final ledger should carry the date, door label, work performed, new key quantity, recipient and any unresolved boundary. It can then be stored with conveyancing or property-management documents without exposing photographs of key cuts. Future residents have a starting point for custody, not a promise that no unauthorised copy exists.
If completion happens remotely, agree a named recipient and a secure handover method before the visit. The locksmith should not leave keys with an unverified neighbour or in an exposed place. The ledger can be acknowledged once the authorised recipient has checked the count.
