Bunnings offers key cutting at many stores, and it can be a convenient option for standard household keys.

But if your key says “Do Not Duplicate”, or if it is part of a building or site key system, the process may not be that simple.

That can be frustrating. If you have a key in your hand, it is natural to feel that you should be able to make another copy when you need one.

The reason some keys cannot be copied casually is not just paperwork. These key systems are usually set up to improve the security of a building, site or shared property. By controlling who can request keys, who can approve them and who has received them, the people responsible for the building can keep better track of access.

If extra keys are copied without approval, that protection can be weakened. There may be more keys in circulation than expected, and the building manager, owners corporation, property manager or site owner may no longer have an accurate record of who can access the site.

Can Bunnings copy a normal house key?

For many standard domestic keys, Bunnings or another hardware store may be able to cut a copy.

Standard key cutting usually depends on whether the store has:

  • the right key blank
  • the right cutting equipment
  • a key that is suitable to copy
  • a staff member or kiosk able to cut that type of key

For a normal household key that is not part of a building access system, this may be simple.

The difference is that some keys are not just ordinary household keys. They may be part of a system designed to protect an apartment building, workplace, school, commercial site or managed property.

Can Bunnings copy a key that says Do Not Duplicate?

Sometimes a key stamped “Do Not Duplicate” is only a standard key with a warning on it.

In that case, the key may be physically copyable if the right blank is available.

However, the stamp usually means the person or organisation responsible for the property does not want copies made without permission.

A retail key-cutting counter may decline to copy it. Even if it can be copied physically, that does not always mean it should be copied without approval.

If the key belongs to a rental property, apartment building, workplace, school, commercial site or managed property, it is better to ask the responsible person first. For the broader question, see can you copy a key that says Do Not Duplicate?.

Can Bunnings copy a restricted key?

A restricted key will usually need to be ordered through the authorised locksmith or supplier responsible for that key system.

Bunnings or a general key-cutting kiosk may not be able to copy it because:

  • the correct key blank may not be available
  • the key profile may be limited to authorised suppliers
  • approval may be required before another key is supplied
  • the locksmith responsible for the system may need to update key records
  • the building or site manager may need to confirm the request

This is by design.

Restricted key systems are commonly used where access matters. The aim is to make it harder for extra keys to appear without the knowledge of the person or organisation responsible for the building.

That can help protect residents, tenants, staff, visitors, contractors and anyone else who relies on the security of the site.

For background, see what is a restricted key?.

Why these keys are treated differently

A normal house key is often just a physical item.

If you have the key and a matching blank is available, a key-cutting service may be able to copy it.

A restricted or site-managed key is different because the key is part of a broader access system.

That system may include:

  • authorised people who can approve new keys
  • a locksmith or supplier authorised to cut the key
  • key blanks that are not available to every retailer
  • records of keys issued
  • rules about who can receive keys
  • records of keys lost, returned or replaced

This process may feel inconvenient when you only need one extra key, but it exists for a reason.

If anyone could make extra copies without approval, the building or site could quickly lose track of how many keys exist and who has them.

Why the key blank matters

To copy a key, the key cutter needs a matching blank.

A key blank is the uncut key shape used before the cuts are made.

Some key blanks are common and easy to obtain. Others are restricted, limited or only supplied to certain locksmiths or authorised dealers.

If Bunnings or another retailer does not have access to the correct blank, it cannot produce a proper copy.

This is one practical reason restricted keys often need to go back through the authorised locksmith.

What if the key is for an apartment?

Apartment keys are often part of a building access system.

The key may open:

  • your apartment door
  • building entrances
  • common areas
  • lifts
  • car parks
  • garages
  • storage areas
  • service areas

Because these keys can affect shared access, the owners corporation, strata manager, building manager, lot owner or property manager may need to approve the request.

This is not only about preventing inconvenience or enforcing rules. It is about protecting the building and the people who use it.

If unapproved copies are made, the building may no longer have a reliable record of who can access shared areas.

If you rent the apartment, start with your property manager or landlord unless the building has given you specific key-ordering instructions.

If you own the apartment, the owners corporation or building manager may still need to approve keys for common areas or building access.

For more detail, see how to order an apartment key.

What if the key is for work?

Workplace keys may also need approval before they can be copied.

This is common for:

  • offices
  • warehouses
  • schools
  • factories
  • commercial tenancies
  • shared business sites
  • plant rooms
  • storerooms
  • staff-only areas

If you are an employee or contractor, do not assume you can copy the key just because you have it.

Ask the site manager, facility manager, business owner or authorised person responsible for the key system.

The approval process helps the business keep track of who has access to the site and which areas they can enter.

Is it illegal for Bunnings to copy a Do Not Duplicate key?

This article is not legal advice.

The important point is that the stamp alone does not tell the whole story.

A key stamped “Do Not Duplicate” may be a standard key with a warning. It may also be part of a restricted key system or a building access process.

Whether a copy should be made depends on the key type, who controls the key, whether approval is required, and the rules for the building or site.

If the key belongs to a property you do not own or manage, do not assume you are allowed to copy it without permission.

What should you do instead?

If Bunnings or another key-cutting service cannot copy the key, or if the key appears to be part of a restricted or building-managed system, the better path is to find out who controls the key process.

You can ask:

  • the building manager
  • the owners corporation manager
  • the strata manager
  • the property manager
  • the landlord or lot owner
  • the facility manager
  • the business owner
  • the site manager
  • the locksmith named on the key or key paperwork

If the key is part of a restricted key system, you may need to order it through the authorised locksmith.

If you need to find a locksmith more generally, the Master Locksmiths directory can help with Australian searches. For restricted keys, still confirm whether the locksmith is authorised for that specific key system.

For the general process, see how to order a restricted key. If you are not sure where to start, see where can I get a restricted key copied?.

What information might you need?

To order a restricted or building-managed key properly, you may need to provide:

  • your name
  • phone number
  • email address
  • building, site or property address
  • apartment, unit, lot or tenancy number
  • key number or marking, if known
  • quantity required
  • reason for the request
  • authorised approver details
  • payment method
  • collection or delivery preference

The exact details depend on the locksmith, key system, building and approval process.

If the key needs approval, see why restricted keys need approval.

Why approval matters

Approval is what helps keep the key system useful.

It helps the responsible person or organisation keep track of:

  • who requested keys
  • who approved them
  • how many keys have been issued
  • who collected or received them
  • which areas those keys can access
  • what happened when a key was lost or replaced

Without that process, the key system becomes less reliable.

If restricted keys are copied without approval, the records may no longer match reality. That can compromise the security of the building or site, especially where the key provides access to shared areas, commercial spaces, staff-only rooms or building services.

Why online ordering can help

Restricted key requests can become confusing when the process relies on paper forms, emails, phone calls and manual payment handling.

A structured online order process can make it clearer:

  • what key is being requested
  • which site or building it relates to
  • who requested it
  • who needs to approve it
  • whether approval has been received
  • whether payment is required or complete
  • whether the key is ready for collection or delivery
  • what record exists of the order

Online ordering does not remove the need for approval. It helps make the authorised process easier to follow. For locksmiths managing these requests regularly, see restricted key ordering software for locksmiths.

Where KeyOrders fits

KeyOrders is being developed to help locksmith businesses manage restricted key requests through a structured online ordering and approval workflow.

It is designed to help locksmiths collect request details, manage authorised approval, track payment status, record fulfilment information and keep clearer order records.

For locksmiths, this can reduce manual follow-up and make restricted key orders easier to review and action.

For customers, tenants, property managers, building managers and authorised signatories, it can make the process clearer and easier to understand.

Summary

Bunnings may be able to copy many standard household keys, but a “Do Not Duplicate” key or restricted key may need a different process.

If the key is a standard key with a warning stamp, it may be physically copyable, but permission may still be required.

If it is a true restricted key, it will usually need to be ordered through the authorised locksmith or supplier responsible for the key system.

That process exists to improve site security by controlling and recording who can receive keys. If extra keys are copied without approval, the building or site may lose track of who has access.

For apartment buildings, workplaces, schools, commercial sites and managed properties, do not assume the key can be copied casually. Check who manages the key system and follow the authorised ordering process.
