Padlocks & Cylinders

Protecting your property starts with reliable, well-matched padlocks and lock cylinders. At John Barnes Group, you can buy padlocks and cylinders online with confidence, knowing you’re choosing quality hardware trusted across residential and commercial projects in Brisbane, throughout Queensland, New South Wales and Australia-wide. From everyday shed padlocks through to high-security restricted cylinders for large facilities, our range is designed to keep people, assets and buildings safe while complementing modern architectural door hardware.

Buy Padlocks Online for Everyday and High-Security Use

Whether you’re securing a garden gate, a factory roller door or a commercial storage cage, the right padlock makes all the difference. Our padlocks range from compact options for lockers and toolboxes through to heavy-duty, hardened-steel designs for high-risk environments. Choose from traditional keyed padlocks, combination padlocks and weather-resistant models engineered to withstand harsh Australian conditions.

For coastal and outdoor applications around Brisbane, Queensland and New South Wales, corrosion resistance is critical. Stainless steel and brass padlocks offer excellent durability in wet or salty environments, while protective covers help shield the mechanism from dust and grime. For general residential use, a quality brass or laminated steel padlock provides a reliable balance of security and value.

Need to streamline access across your site? Keyed-alike padlocks allow multiple locks to be operated with a single key, simplifying key management for trades, maintenance teams or facility managers. For more complex sites, master-keyed padlock suites can be designed as part of a broader access control system, ensuring the right people have the right level of access when they need it.

Premium Cylinders for Modern Architectural Door Hardware

The cylinder is the heart of your door lock, and choosing the right profile and keying system is essential for both security and convenience. Our range of lock cylinders supports common Australian residential and commercial door hardware, from standard entrance sets through to premium architectural mortice locks.

Working with leading brands such as Lockwood, Dormakaba, Barben and Zanda, we supply cylinders to suit a wide variety of door types and hardware styles. Whether you’re fitting out a contemporary apartment building in Brisbane, upgrading an office in New South Wales or managing multi-site facilities Australia-wide, we can help you select cylinders that integrate seamlessly with your existing or planned architectural door hardware.

Finishes such as satin stainless steel, polished brass, matte black and other contemporary tones help you achieve a cohesive look across front doors, internal doors and external entry points. That means you can specify cylinders that offer strong security without compromising on the clean, modern lines your project demands.

Restricted Key Systems and Advanced Keying Options

For higher security applications, restricted cylinders offer an added layer of protection and control. With restricted keyways, keys can only be duplicated by authorised parties, helping prevent unauthorised copies and giving building owners and managers greater peace of mind.

John Barnes Group can assist with tailored keying options, including:

• Keyed alike – multiple locks and padlocks operated by one key for simplicity.
• Keyed to differ – each lock has its own unique key for maximum separation.
• Master key systems – tiered access for different user groups across a site or portfolio.

These solutions are ideal for schools, health facilities, commercial buildings, government sites and industrial premises across Queensland, New South Wales and broader Australia. By pairing the right cylinder types with brands you already trust, such as Lockwood and Dormakaba, you can build a secure and scalable system that grows with your facility.

Padlocks & Cylinders for Residential and Commercial Projects

Our padlocks and cylinders are carefully selected to suit both residential and commercial environments. Homeowners can choose reliable entrance cylinders and outdoor padlocks to secure front doors, side gates, garages and garden sheds, with finishes that coordinate with Barben and Zanda handles, pulls and hinges for a unified look.

For commercial and industrial customers, we support everything from small business premises through to national portfolios. Facility managers, strata managers and builders rely on John Barnes Group for padlocks and cylinders that meet the demands of high-traffic doors, frequent access and demanding environmental conditions, all while aligning with Australian standards where applicable.

Whether you’re working on a boutique renovation in inner-city Brisbane or a large-scale development in regional Queensland or New South Wales, our team can help you specify padlocks and cylinders that suit your security level, aesthetic requirements and project budget.

Choosing the Right Padlock or Cylinder

Security Level and Application

Start by considering the risk level and what you’re protecting. Low to medium-risk applications such as garden sheds or internal storerooms may be well served by standard padlocks and conventional cylinders. For higher-risk assets, external gates or remote sites, look for heavy-duty padlocks with hardened shackles and security-rated cylinders designed to resist forced entry and tampering.

Environment and Durability

Australia’s climate can be tough on hardware, particularly outdoors. For coastal or exposed locations, choose weather-resistant padlocks and cylinders with corrosion-resistant materials like stainless steel or brass. Protective shrouds and covers help shield mechanisms from dust, salt and moisture, extending the life of your investment and keeping your locks operating smoothly for longer.

Keying and Access Control

Think about how many people need access, and how you’ll manage keys over time. A simple keyed-alike solution may be perfect for a small business or household, while a larger commercial site might benefit from a master key system that provides selective access. Restricted cylinders from trusted brands such as Dormakaba and Lockwood offer additional key control, which is particularly valuable in multi-tenant buildings and critical infrastructure.

Finish and Aesthetic Integration

Security hardware doesn’t have to detract from your design. With options in satin chrome, polished brass, matte black and other popular finishes, you can match your cylinders to Barben and Zanda door furniture, hinges and accessories for a cohesive architectural look. This is especially important on front doors and main entries, where first impressions count.

Compatibility with Existing Hardware

If you’re upgrading or replacing existing locks, make sure your new cylinders are compatible with the current hardware. Many of our cylinders are designed to suit common Australian lock bodies, simplifying upgrades in homes and businesses across Brisbane, Queensland and New South Wales. When in doubt, our team can help you match profiles and recommend appropriate options.

Installation and Maintenance Guidance

Most standard cylinder and padlock installations are straightforward for experienced trades and locksmiths, and many residential cylinder upgrades can be completed with basic tools and careful attention to the manufacturer’s instructions. For complex master key systems, commercial fire doors or specialised security hardware, we recommend engaging a qualified locksmith or installer to ensure everything is fitted correctly and performs as intended.

Once installed, regular maintenance will keep your padlocks and cylinders working reliably. Occasional cleaning, appropriate lubrication and prompt replacement of damaged or heavily worn components all help maintain security and extend the life of the hardware. If you’re unsure about product selection or maintenance best practice, the John Barnes Group team is here to provide guidance.

Frequently Asked Questions

Can I buy padlocks keyed alike online?

Yes. Many of our padlocks can be supplied keyed alike so multiple locks operate from the same key, making life easier for households, trades and facility managers. When buying padlocks online, simply look for keyed-alike options or contact our team if you need a customised keying arrangement across padlocks and door cylinders.

What type of padlock is best for outdoor use?

For outdoor applications, especially around coastal areas in Queensland and New South Wales, we recommend weather-resistant padlocks made from brass or stainless steel, or models with protective covers. These materials handle moisture and salt better, helping prevent corrosion and ensuring the lock continues to operate smoothly over time.

What is a restricted cylinder and do I need one?

A restricted cylinder uses a specially designed keyway where keys can only be duplicated by authorised parties, usually against recorded approvals. This provides greater control over who can copy keys and is ideal for commercial buildings, strata properties, schools and facilities where security and key management are critical. Many Brisbane and Australia-wide projects choose restricted cylinders for peace of mind.

Are your cylinders compatible with Lockwood and Dormakaba hardware?

We supply cylinders designed to work with common Lockwood, Dormakaba and other leading-brand lock bodies used widely across Australia. If you’re retrofitting or expanding an existing system, we can help you identify the correct cylinder type and keying options to maintain compatibility and performance.

Can you help design a master key system?

Yes. John Barnes Group can assist with the design and supply of master key systems, from simple two-level hierarchies to more complex arrangements for multi-building sites. We’ll work with you to understand your access requirements and recommend padlocks and cylinders that integrate into a secure, scalable system.

Do you ship padlocks and cylinders Australia-wide?

We support customers in Brisbane and throughout Queensland, New South Wales and Australia-wide. Our online store makes it easy to order padlocks and cylinders for residential, commercial and industrial projects, with reliable delivery and knowledgeable support if you need assistance choosing the right products.

How do I know which cylinder I need for my door?

The correct cylinder will depend on your lock type, door thickness, function and desired keying arrangement. If you’re unsure, you can provide us with photos and basic measurements, or details of your existing hardware. Our team can then recommend suitable cylinder options from trusted brands such as Lockwood, Dormakaba, Barben and Zanda.

Do I need a locksmith to install a new cylinder?

Some straightforward replacements can be handled by experienced DIYers or trades, but for best results—especially with restricted systems, fire doors or commercial locks—we recommend using a qualified locksmith or professional installer. This ensures your new cylinder operates correctly, maintains door compliance where required and delivers the security performance you expect.
