Quick answer
- Rekey based on lost control, not an arbitrary calendar alone.
- Inventory doors, cylinders, keys, holders, and authorizers first.
- Do not block required egress or alter fire-rated hardware casually.
- A written issuance and return process reduces future rekeys.
- Temporary vendor keys need an owner and a return date, not an open-ended handoff.
The trigger is lost control
A key does not need to be visibly stolen before it becomes a risk. If a restaurant manager leaves with an unreturned back-door key, a warehouse contractor could have copied a gate key, or nobody knows who holds the office suite copies, the business cannot prove control. That is the practical rekey trigger.
A routine staff departure is lower risk when every numbered key is returned and no sensitive access was involved. A contentious departure, missing key, or key tied to an address is different. Document the facts and have the authorized decision-maker set the response.
The commercial rekeying service covers confirmed work. The commercial locksmith hub helps separate rekeying from repair and urgent access problems.
Common moments to review access

| Event | Question | Likely next step |
|---|---|---|
| Employee departure | Were all keys returned and could copies exist? | Document return or rekey affected cylinders |
| Lost key | Can it be tied to the site or a sensitive door? | Escalate based on exposure |
| Vendor change | Did temporary access become permanent? | Recover keys and review affected entries |
| Lease or management change | Who held prior copies? | Build a new key-control baseline |
| Break-in attempt | Was hardware or key control compromised? | Inspect, repair, and rekey as facts require |
At a small shop along Denton Highway, one exterior key may open nearly everything. At a multi-tenant building downtown, the suite, common doors, roof access, and mechanical rooms can involve different authorities. Do not order a blanket change until the affected cylinders are mapped.
A scheduled review also catches quiet drift. Extra copies accumulate during holiday coverage, cleaning changes, and maintenance projects. Six months later, nobody remembers why a key was made.
Build the door and key inventory
- 1List openings
Record exterior doors, suites, stockrooms, gates, and sensitive rooms.
- 2Name the cylinder
Identify which keys operate which locks without publishing the map broadly.
- 3List holders
Record person, role, issue date, and expected return.
- 4Name the authorizer
Decide who may approve keys, rekeys, and access changes.
Do not ask for a master-key design unless the business has confirmed that service and its operational requirements with a qualified provider. This article does not claim Hi-Q installs master-key systems. The immediate job is simpler: understand current access and correct the cylinders within confirmed scope.

Photograph hardware for identification, but keep door labels, alarm information, and access maps out of casual messages. A key-control inventory is sensitive business information.
Coordinate the change
Choose a time that keeps authorized staff available and does not trap workers or interrupt required exits. Commercial doors can involve panic hardware, closers, fire labels, and landlord-controlled components. Rekeying a cylinder should never be treated as permission to defeat those systems.
Notify only the people who need to know, stage new keys, collect old keys, and test each affected door after the work. A loading door near I-35W may behave differently under wind or delivery traffic than it does during a quiet inspection.
If hardware is loose, misaligned, or damaged, a rekey alone is incomplete. Route those symptoms to commercial repair and document which condition was corrected.
Keep control after the visit
Issue the smallest practical number of copies. Mark them with internal codes that do not reveal the business name or address. Require a signature or digital acknowledgement, and make return part of offboarding rather than a favor someone remembers later.
Review the log after vendor projects, seasonal staffing, management changes, and incidents. A quarterly glance can be enough for a small business. A busy property may need a tighter cadence based on actual turnover and access sensitivity.
If the event is urgent or disputed, use the contact page to share non-sensitive job details and call to confirm current availability. Keep HR, lease, and legal decisions with the appropriate professionals.

After the change, run a short handoff with supervisors. Show which old keys no longer work, distribute new copies against the log, and name the person who can authorize another copy. Do not leave surplus keys in an unlocked desk. For cleaners or delivery access, set a return date instead of creating an indefinite temporary key. Recheck the log during the next staffing change. A rekey restores a boundary once; the process that follows is what keeps that boundary intact.

Frequently asked questions
Should a business rekey after every employee leaves?
Not necessarily. Base the decision on returned keys, copy risk, role sensitivity, and the doors the person could access.
Is rekeying the same as replacing commercial locks?
No. Rekeying changes the operating key in compatible serviceable cylinders. Replacement changes hardware and may be needed for damage or incompatibility.
Can we rekey an exit door ourselves?
Commercial openings can involve life-safety, lease, and code requirements. Do not alter required egress or rated hardware without qualified review.
What belongs in a key log?
Record an internal key ID, holder, role, issue date, doors or group authorized, return date, and approving person.
