Business key control after a staff or tenancy change

Start with an accurate key register

Record the key identifier, the doors it operates, who holds it and when it was issued or returned. Include contractors and other authorised keyholders. A returned key does not establish whether copies were made, so consider the access risk as well as the number physically collected.

Separate mechanical keys from electronic access

A cylinder rekey changes access through that cylinder. It does not remove an alarm code, cancel a swipe card, reset a garage remote or revoke an app account. Review those separately with the appropriate system administrator or provider.

For shared buildings, check with the owner or building manager before altering locks connected to common areas or a master-key system.

Plan the right scope with your locksmith

List the affected entrances, who needs ongoing access and whether some people should open only particular doors. Ask whether the existing cylinders can be rekeyed, whether keying alike is appropriate, or whether a managed master-key arrangement merits discussion.

Provide the site address, an authorised contact, access arrangements and trading hours. Explain any problem that prevents normal entry or secure closing so the urgency can be assessed.

Check the handover and keep records current

• Confirm the locks included and how many keys were supplied.
• Test authorised access and normal closing operation.
• Update the register before distributing new keys.
• Record any doors or systems that were outside the work scope.
• Agree how future lost keys and staff departures will be handled.
