Premium Locks & Latches for Every Door

Front Door Locks for Lasting Security

Your front door is the main security barrier for your home or business, so choosing the right lock is essential. Our range includes robust entrance locks and latches suitable for timber, aluminium and steel doors, with options for single and double doors. Lockwood and Dormakaba front door locks are known for their reliability in Australian conditions, while Barben and Zanda offer stylish options that complement contemporary and architectural facades. Choose from deadlatches, mortice locks and entrance sets that balance security, ease of use and modern aesthetics.

Internal Door Latches for Smooth Everyday Use

Internal doors may not demand the same level of security as external doors, but they still need to feel solid and operate smoothly. Our selection of tubular latches, privacy latches and passage sets is ideal for bedrooms, bathrooms, hallways and living areas in residential and commercial settings. Many ranges from Barben, Lockwood and Zanda are designed to match handles and levers across your project, so you can create a consistent look throughout apartments, offices or homes while maintaining dependable performance on every internal door.

External and Utility Door Solutions

For side access doors, plant rooms, storerooms and utility areas, you need hardware that can withstand frequent use and exposure to the elements. We offer heavy-duty latches and locks suitable for external doors, including options from Dormakaba and Lockwood that are engineered for Australian commercial and industrial environments. Choose from keyed entrance sets, deadlocks and complementary hardware that help keep service areas secure without compromising day-to-day access for staff or contractors.

Architectural Door Hardware in Modern Finishes

Contemporary Styles to Match Your Design

Locks and latches don’t just provide security; they also contribute to the overall look of your doors. Our architectural door hardware range includes minimalist, contemporary and premium designs that suit modern residential and commercial projects. Barben and Zanda specialise in stylish hardware lines that pair beautifully with square-set doors, flush panels and designer entryways, while Lockwood and Dormakaba offer clean, streamlined forms that work equally well in traditional or modern fit-outs.

Popular Finishes: Matte Black, Stainless Steel, Brass and More

Finish selection plays a big role in tying your project together. Choose matte black locks and latches for a bold, modern look that stands out against light doors, or opt for stainless steel and brushed nickel for a timeless, low-maintenance finish. Brass tones can add warmth and character to both residential and commercial interiors. Across our range of Barben, Dormakaba, Lockwood and Zanda products, you will find a variety of finishes designed to coordinate with matching door levers, pull handles, door stops and other accessories.

Consistency Across Residential and Commercial Projects

Architects, designers and builders often need a unified hardware palette across mixed-use developments, multi-residential buildings and commercial spaces. Our locks and latches have been curated to integrate seamlessly into broader hardware schedules, making it easier to maintain consistency from front door to back office. Select coordinated series from brands like Lockwood, Dormakaba, Barben and Zanda to streamline specification and ensure that every door, from high-traffic entries to quiet internal offices, feels cohesive and well considered.

Choosing the Right Lock or Latch for Your Application

Residential Locks & Latches

For homes and apartments across Brisbane, Queensland and New South Wales, the focus is often on combining security with style. Front and back doors typically benefit from entrance sets or deadlocks, while bedrooms and bathrooms are suited to privacy latches and non-locking passage latches. Our residential range includes solutions for new builds and renovations, so it’s easy to upgrade older doors with modern architectural hardware without compromising safety or aesthetics.

Commercial and Industrial Requirements

Commercial and industrial sites have additional considerations such as compliance, traffic flow and durability. Offices, schools, healthcare facilities and retail spaces often require a blend of locks, latches and compatible door hardware that supports access control, fire doors and emergency egress solutions specified elsewhere in the project. With trusted brands like Dormakaba and Lockwood in the mix, you can source locks and latches capable of handling high-traffic use while integrating with broader security and access systems specified by your project team.

Door Type, Function and Hardware Compatibility

When selecting a lock or latch, it helps to consider the type of door, the function of the room and any hardware already in place. Internal doors may only need simple passage latches, while service and storeroom doors might require keyed locks. Sliding doors, cavity sliders and specialty doors often demand dedicated latching options designed for smooth operation in tight spaces. Our range is chosen to work alongside common Australian door constructions and frame types, helping to simplify selection for both small residential jobs and large commercial fit-outs.

General Installation Guidance

Most locks and latches are designed for straightforward installation by a qualified installer, builder or experienced DIYer, depending on the product and application. When replacing existing hardware, it’s often helpful to match backset and preparation type to minimise additional door work. For new doors, choosing hardware early in the process makes it easier for your door supplier or installer to prepare correctly. Always follow the manufacturer’s instructions and engage appropriate trade professionals where required, particularly for commercial or fire-rated door sets.

Frequently Asked Questions

What is the difference between a lock and a latch?

A latch is the mechanism that holds a door closed, typically operated by a handle or lever. A lock adds a security function, usually through a key, thumbturn or digital mechanism that prevents the door from being opened without authorisation. Many entrance sets combine both a latch and lock in one assembly, while some applications use a simple latch with a separate deadbolt for added security.

Which locks and latches are best for front doors?

Front doors generally benefit from a robust entrance lock or a combination of a latch and a deadlock. Look for quality products from trusted brands such as Lockwood and Dormakaba, which are widely used across residential and commercial properties in Australia. Consider the level of security you require, your preferred keying system and the look you want to achieve with your handles and hardware.

Can I use the same latch type on all internal doors?

In many homes and offices, simple passage latches are used for most internal doors, with privacy latches installed on bedrooms and bathrooms. Using the same latch type and a coordinated handle range, such as those from Barben or Zanda, can create a consistent look and feel throughout the building. However, specialised areas like plant rooms or staff-only spaces may require keyed locks rather than standard latches.

Are your locks and latches suitable for commercial use?

Yes, we stock a variety of locks and latches suitable for commercial and industrial environments across Brisbane, Queensland, New South Wales and Australia-wide. Products from Dormakaba and Lockwood are commonly specified in offices, schools, healthcare facilities and other high-traffic sites, offering reliable performance and compatibility with broader security systems where required.

What finishes are available for locks and latches?

Our range includes popular finishes such as matte black, stainless steel, brushed nickel and brass tones, along with other contemporary options to coordinate with your overall hardware specification. Many Barben, Zanda, Lockwood and Dormakaba series are available in matching finishes across locks, latches, levers and accessories, helping you maintain a cohesive aesthetic throughout your project.

Do I need a professional to install my lock or latch?

Some basic latch replacements can be handled by experienced DIYers, but many installations—particularly for front doors, commercial doors or fire-rated assemblies—are best left to qualified installers or locksmiths. Professional installation helps ensure proper door preparation, alignment and operation, which in turn supports security, durability and user safety.

Can I buy locks and latches online for projects outside Brisbane?

Yes, you can buy locks and latches online from John Barnes Group for delivery across Queensland, New South Wales and most regions Australia-wide. This makes it easy for builders, facility managers and homeowners to access quality architectural door hardware regardless of where the project is located.

How do I choose the right lock or latch for a specific door?

Consider the door’s location (front, internal, external, utility), the required security level, how frequently it will be used and the hardware style you are aiming for. Once you know the function—such as passage, privacy, entrance or deadlock—you can narrow down options by finish and brand. Matching your selection to existing hardware from Barben, Dormakaba, Lockwood or Zanda can also help maintain visual consistency.

Are your locks and latches compatible with Australian doors?

The products in our locks and latches category are selected to suit common Australian door constructions and hardware preparations. While details vary between models, most are compatible with standard door thicknesses and backsets used across residential and commercial buildings in Australia. Always check product information and engage your installer or door supplier if you are unsure.

Can I coordinate locks and latches with other door hardware?

Yes. Many product ranges include matching door levers, pull handles, door stops and accessories, allowing you to coordinate all architectural door hardware across your project. This is particularly useful in multi-residential and commercial developments where a consistent hardware look is important from the main entry right through to internal offices and amenities.
