Put the keys beside a door list
For an incoming tenant or a change in staff responsibilities, start with the ordinary entrances the business actually uses. List the front door, staff door and individual suite separately where relevant. Match the keys you have to those doors instead of assuming every similar-looking key is interchangeable.
Record returned copies and any copies whose whereabouts are uncertain. This is not an accusation or a reason to replace everything automatically. It gives the person making the access decision a more accurate picture. A commercial locksmith enquiry can then focus on the door and outcome you mean.
Find the person who can say yes
A business occupies a unit, but the landlord or property manager may be responsible for part of the entrance hardware. Ask who can approve a change to this particular lock. Shared access to a building is a separate matter from a tenant's private door, even when the same staff use both.
Have the approving person's details ready and decide who will meet at the premises. At an Opa-locka shop or office, include the street number, suite and whether you mean the customer entrance or another pedestrian door. Avoid arranging a visit around only the trading name or a nearby landmark.
Access changes and damage differ
If the lock works normally but old copies should no longer be used, discuss rekeying suitable hardware. Ask which locks are included and who receives the finished keys. Do not assume that unlike locks can be made to share one key.
If a key jams or the door does not latch, describe that as well. A key-record problem does not explain every hardware fault. This guide concerns ordinary business doors, rather than electronic access systems, industrial shutters, hangar doors or restricted airport access.
Leave a clear handover behind
Confirm the proposed scope and charge questions before approving work. Afterwards, keep an up-to-date record of which approved person received each key. That simple record gives the next handover a clearer starting point than an unlabelled bundle in a drawer.
