Business key control when staff or tenants change

Begin with the doors and people involved

A business access review should start with a clear inventory: which entrances exist, who needs access and who can authorise changes. A small shop may have a front entrance, rear delivery door and internal office. Another premises may share its main entrance with other occupiers. Those differences matter before any lock replacement is priced.

Record the keyholder, date issued, doors the key operates and expected return date where relevant. Use a private reference rather than putting a complete address or sensitive door description on the physical key. Keep the register accessible to the responsible manager and limit unnecessary sharing of the information it contains.

Treat a returned key as one part of the handover

When a member of staff or contractor leaves, reconcile the issued keys against the register. Note what has come back and what remains unaccounted for. The exercise is easier if temporary loans were recorded at the time rather than passed informally from one person to another. Agree who follows up missing sets.

Recovering an original key does not itself establish whether other copies exist. Consider the history of the key, the areas it opens and your business's access policy. The decision to change a lock should reflect those circumstances rather than a blanket assumption that every departure requires the same work.

• Reconcile each issued key against its current holder.
• Identify any shared, loaned, lost or unreturned set.
• Confirm who still requires access after the handover.
• Record who is responsible for approving and receiving replacement keys.

Understand what a lost mechanical key means

Changing a record does not disable an ordinary mechanical key. If the decision is that an unaccounted-for key must no longer work, discuss suitable changes to the relevant locks with the system's responsible provider. Identify every door that key can operate before assuming that one replacement resolves the concern.

A master-key or restricted-key arrangement needs its own system information and authorised supplier involvement. Electronic access has different administration and compatibility requirements again. Explain the existing setup when enquiring rather than treating these systems as interchangeable. Specialist systems should be referred to an appropriately qualified provider; a general business lock enquiry does not confirm that every system is supported.

Plan a lock change around business access

For a tenancy change, agree which doors belong to the premises and which remain under a landlord or managing agent's control. Identify the authorised person who will approve the work and meet the locksmith. Discuss delivery times, customer access and any appointment restrictions so a planned visit can be scoped realistically.

Describe the doors and current problem, then ask which work can be offered for the hardware. Confirm the quote, supplied keys and process for approving any additional parts. Do not alter emergency-exit or specialist door arrangements as an incidental part of a routine access change; have the responsible building manager establish the appropriate scope and provider first.

Close the loop after the work

Update the register when new keys are issued, withdraw obsolete sets and confirm that the right people can enter when required. Record the exact replacement hardware and keep the invoice with the premises information. Establish a simple reporting route for the next lost key or staff change. Regularly reconciling a short, accurate register is more useful than keeping a detailed document that nobody updates.
