Employee turnover is normal. Loose key control does not have to be. When a former employee, contractor, vendor, or tenant may still have a working key, commercial rekeying lets the business update access without replacing every lock.
For offices, storefronts, suites, warehouses, and managed properties, rekeying is one of the simplest ways to restore control after roles change.
When businesses should consider rekeying
The right time to rekey is any time you no longer know who has a working key. That includes staff departures, manager changes, lost key rings, tenant turnover, contractor access, cleaning crew changes, and vendor changes.
Rekeying is especially important when keys were issued informally and no accurate key log exists.
Which doors should be included
Start with exterior entrances, back doors, office doors, stock rooms, file rooms, storage areas, employee entrances, and any room that holds cash, inventory, records, tools, or equipment. For multi-tenant spaces, confirm who is authorized to request each change.
Master key systems need extra care
If the business uses a master key system, one lost or unreturned key may affect more than one door. A locksmith can help determine whether only certain cylinders need to change or whether part of the master system should be rebuilt.
Access control may be worth considering
If keys are constantly being issued, lost, or returned late, keypad, card, or fob access may be a better long-term fit for some doors. Physical locks still matter, but electronic access can make it easier to add and remove users.
Common Questions
Should a business rekey after an employee leaves?
If the employee had keys that may not have been returned or copied, rekeying is a practical way to restore key control.
Can a commercial rekey be done without changing hardware?
Usually, yes, when the existing locks are in good condition. Rekeying changes which keys work while keeping the hardware.
Can rekeying work with a master key system?
Yes, but it must be planned carefully so manager and tenant access still works as intended.
