Door Locks

Door locks are the first line of defence for any property, whether it’s a family home, strata complex, or commercial site. A well-chosen lock provides everyday convenience while protecting against break-ins and meeting compliance standards. From security door locks for main entries to sliding door locks and timber door locks for internal fit-outs, Doric offers a complete range engineered for Australian conditions.

When safety, compliance, and usability matter, the right lock makes all the difference.

Types of Door Locks

Different doors need different solutions. Doric’s range covers every style and requirement:

Hinged Door Locks

Designed for standard swing doors, hinged locks range from simple entrance sets to keyed commercial-grade options. They’re versatile enough for both homes and high-traffic offices.

Sliding Door Locks

Purpose-built for patio and internal sliders, these locks secure panels against lifting or forced entry while staying easy to use day-to-day.

Key Features & Benefits

Doric door locks deliver practical advantages across all environments:

• Range of styles – keyed, mortice, sliding, and dummy lock options.
• Durability – built to handle heavy use in both residential and commercial settings.
• Ease of installation – retrofit-friendly designs that align with common cut-outs.
• Customisation – interchangeable lock cylinders to suit keying systems.

Applications

Door locks play different roles depending on setting:

• Residential properties – secure front and back entries with robust security door locks, and fit out internal doors with timber door locks.
• Strata complexes – ensure compliant access with keyed sliding door locks and standardised cylinders across multiple units.
• Commercial buildings – protect offices and service areas with heavy-duty hinged door locks and mortice solutions.
• Public facilities – meet accessibility and compliance needs with versatile, easy-to-use entry hardware.

Compatibility Across Door Types

Locks need to work seamlessly with their door materials:

• Aluminium frames – slimline locks built for modern extrusions.
• Timber doors – robust fittings designed to manage seasonal movement.
• uPVC systems – compatible hardware for insulated and multi-chamber frames.
• Sliding systems – locks designed to integrate with sliding door locks and keep panels secure.

For full door hardware performance, pair locks with dummy locks where non-locking handles are needed, or with keyed door cylinders for custom access control.

Maintenance & Replacement Guidance

Like all hardware, locks need care to stay reliable:

Maintenance tips:

• Lubricate lock cylinders with graphite or silicone spray annually.
• Check screws and strike plates for tightness.
• Wipe handles and exposed parts to prevent corrosion. 

When to replace:

• Keys stick or the cylinder becomes difficult to turn.
• Handles feel loose even after tightening.
• Visible corrosion on external fittings.
• Lock no longer aligns with the strike plate.

Replacement is often straightforward, with Doric locks designed to align with existing cut-outs on timber, aluminium, or uPVC doors.
