Rekeying Commercial Locks in Osborne Park: When Staff Change, Your Keys Should Too

Q: What does rekeying actually do to your commercial lock?

Rekeying involves a locksmith replacing the internal key pins in your lock cylinder and cutting a new key, rendering the old key useless while keeping the existing hardware intact.

Q: When should you rekey vs. replace the lock entirely?

Rekeying is suitable when the lock is mechanically sound but key control is compromised. Replacement is necessary if the lock is damaged, corroded, or outdated.

Q: How do restricted keyways change the risk after a staff departure?

Restricted keyways prevent unauthorized duplication of keys, reducing security risks when a key is lost or unreturned. They can only be duplicated by licensed locksmiths.

Q: When should Osborne Park businesses consider access control instead?

If rekeying frequently due to staff changes, consider electronic access control for immediate access removal and audit trails, which traditional locks cannot provide.

Q: Do I need to rekey if the employee handed back their key?

Yes, because returning a key does not ensure a copy wasn't made. Rekeying ensures previous keyholders no longer have access.

Q: What happens if a master key is lost in a commercial building?

A lost master key should be treated as an emergency, as it can access multiple zones. Immediate rekeying of all affected cylinders is necessary.

Q: Is rekeying cheaper than installing an access control system?

Rekeying is cheaper upfront, but frequent rekeying due to staff turnover can become more costly than installing an electronic access control system.

An employee finishes their last shift at your Osborne Park business and somewhere in their pocket is a key to your front door. You have no way to confirm it wasn’t copied, shared, or retained on purpose. This is one of the most common and most preventable security exposures local businesses face — and the fix is simpler than most owners realise.

Why Is Staff Turnover a Physical Security Problem for Osborne Park Businesses?

Key control ends the moment a departing employee walks out the door.

When a staff member leaves, you lose visibility over every key they held. A key on a standard keyway can be copied at most hardware stores — you would never know it happened. In businesses with regular turnover — retail, hospitality, trade services — this problem compounds with every departure.

The risk is not hypothetical. An after-hours entry with a copied key leaves no forced entry, no noise, and no obvious evidence. By the time you notice something missing, the window has already closed. Acting at the point of departure — not after an incident — is how you stay ahead of it.

If your business uses a master key system, a single unreturned key may open multiple zones — offices, storage, server rooms — not just one door. The scope of a lost master key is covered in detail in our related guide on master key systems for Osborne Park businesses.

What Does Rekeying Actually Do to Your Commercial Lock?

New key control, same hardware — here's the mechanics in plain terms.

Rekeying means a locksmith removes your lock cylinder, replaces the internal key pins with a new set, and cuts a fresh key to match. The old key stops working immediately. The lock body, door hardware, and strike plate stay exactly where they are — you are paying for labour and new pins, not new hardware.

For commercial premises with multiple entry points, a locksmith can rekey all cylinders to operate on a single new key during the same visit. This is especially useful when you are restructuring access after a staff change and want to consolidate who holds what.

When Should You Rekey vs. Replace the Lock Entirely?

Two different problems — key control vs. hardware condition — need different solutions.

Rekeying is the right call when the lock is mechanically sound and the only issue is who holds the keys. If a staff member has left, a key is unaccounted for, or you’ve had a tenancy changeover, rekeying resolves the problem at the lowest cost.

Full replacement makes sense when the lock is visibly damaged, corroded, stiff, or is a low-security grade that no longer meets your needs. Perth’s coastal climate accelerates corrosion on exterior hardware — what looks fine from outside can be mechanically compromised inside.

•Rekey — staff departure with a functioning, good-condition lock
•Rekey — lost or unreturned keys where lock hardware is intact
•Rekey — tenancy changeover or end of a contractor's access period
•Replace — lock is stiff, corroded, cracked, or was forced during a break-in
•Replace — hardware is outdated and no longer meets current security standards
•Upgrade — consider high-security locks or access control if turnover is frequent

How Do Restricted Keyways Change the Risk After a Staff Departure?

Not all keys are equal — the keyway type determines how easy duplication is.

On a standard keyway, a departed employee can have their key copied at a hardware store or shopping centre kiosk with no questions asked. Restricted keyways prevent this — keys can only be duplicated by licensed locksmiths who are specifically authorised and registered to that system.

For Osborne Park businesses dealing with regular staff turnover, a restricted keyway system means a lost or unreturned key carries far less ongoing risk. You still rekey to invalidate the missing key — but you eliminate the duplication threat at the same time. It’s one of the most cost-effective security upgrades available without changing your entire lock infrastructure.

If you are rekeying after a staff departure and your system currently uses a standard keyway, ask your locksmith to assess whether upgrading to a restricted keyway makes sense at the same time. You are already paying for the callout — the long-term security uplift can be significant. For businesses weighing broader security upgrades, combining a restricted keyway with other improvements is a smart use of a single visit.

When Should Osborne Park Businesses Consider Access Control Instead?

Traditional locks aren't obsolete — but they have a ceiling when turnover is constant.

Rekeying is the correct response every time key control is lost. But if you are rekeying multiple times a year due to regular staff changes, the cumulative cost and disruption is a strong signal that electronic access control may be the better fit. With a keypad, key card, or biometric system, removing a departing employee’s access is immediate — no locksmith callout required.

Access control systems also create an auditable record of who entered where and when — something purely mechanical traditional locks cannot provide. For Osborne Park businesses managing multiple staff across shifts, that visibility has real operational value. Our related article on high-security locks and access control for Osborne Park industrial and retail properties covers the technology options in detail.

For businesses exploring keyless entry and access control options, a commercial locksmith can assess your entry points and recommend hardware that integrates with your existing doors without major structural changes.

Frequently Asked Questions

Straight answers to what Osborne Park business owners ask most often.

How quickly can a commercial rekey be done after a staff member leaves?

A licensed locksmith can rekey most standard commercial cylinders in a single visit. Ultimate Lock & Security operates 24 hours a day, 7 days a week — so if a staff member departs unexpectedly, you can have new key control the same day by calling 0481 365 802.

Do I need to rekey if the employee handed back their key?

Handing back a key does not guarantee a copy was never made. If your locks use a standard keyway, the returned key may already have a duplicate in circulation. Rekeying is the only way to be certain previous keyholders no longer have access.

What happens if a master key is lost in a commercial building?

A lost master key exposes every door that key accesses — potentially the entire building. You should treat it as an emergency, call a locksmith immediately, and rekey all affected cylinders the same day. Do not wait to see if the key turns up.

Is rekeying cheaper than installing an access control system?

A single rekey costs less upfront than an access control installation. However, if your business is rekeying frequently due to staff turnover, the cumulative cost can exceed what a quality electronic system would have cost — with less visibility and more disruption along the way.
