Standard spring-lock door latches are gradually turning inadequate against modern bypass methods like lock “shimming” or plastic card sliding, leaving properties highly vulnerable to quick, quiet forced entries. To safeguard your family and fully meet the modern Australian home insurance policy criteria, upgrading to a high-quality, solid-core deadlock is an absolute necessity for Melbourne residents.
At Open Locksmiths, we bring over two decades of professional structural security experience to every residential project across Melbourne and its surrounding suburbs. Our highly trained, fully licensed team approaches home protection with a commitment to premium craftsmanship, rapid response, and uncompromised structural integrity.
Unlike cut-rate services that utilise fragile, generic imported hardware, our mobile workshops arrive fully equipped with top-tier, industry-recognised Australian brands such as Lockwood, Whitco, and Gainsborough. We meticulously select architectural-grade locking mechanisms designed specifically to withstand harsh local climate conditions and aggressive physical tampering. By choosing our experienced team, you receive an efficient, damage-free installation that seamlessly pairs advanced security engineering with a sleek aesthetic tailored to your specific door type.
We will attend to your location to help you re-gain access to your home or business.

Structural Woodcrafting and Alignment Precision
A deadlock is only as secure as the mathematical accuracy of its installation. If the alignment between the bolt and the strike plate is misaligned by even a millimetre, the mechanism will bind or fail to dead-lock, leaving the door vulnerable to physical kicking. Our technicians carry specialised commercial-grade routing tools inside their mobile service Utes, ensuring clean, factory-level woodcrafting on every job.
The installation follows a meticulous, non-destructive approach as follows:
- Measure: We check the door construction and measure the backset precisely (usually 60mm).
- Bore: With the help of an installation jig made out of rigid metal, we clean holes for the cylinders that are drilled in both face and edge.
- Mortise: Timber chisels are used to make a slight mortising that allows the faceplate to fit precisely flush.
- Mount: Finished by bolting the cylinders securely using high-strength steel tie-bolts without causing the pins to bind.
- Anchor: A solid strike plate is mounted using 75mm structural screws into the wall stud.
Ensuring Deadlock Configurations and Compliance with Regulations
Choosing the right deadlock involves striking a balance between architectural considerations of your building and local laws concerning safety requirements. The following considerations must be met regarding security locks in the state of Victoria, Australia. For instance, while a double-cylinder deadlock offers maximum security against intruders breaking nearby glass to reach inside, installing them on specific apartment entry doors or rental properties can be a direct legal violation if it prevents keyless emergency egress during a fire.
To bridge this gap, we guide you through the ideal choices:
- Single-Cylinder: Features a convenient interior thumbturn knob for flawless, rapid exit speed.
- Double-Cylinder: Requires a physical key on both sides for complete glass-shatter defence.
- Captive Key: A versatile hybrid system where the key locks permanently inside while you are home, functioning exactly like a thumbturn.
Our local compliance knowledge ensures your home remains fully insurable without ever compromising life safety. Reach out for efficient deadlock installation and replacement to bolster your security.
Protect Your Home With Deadlock Installation
A deadlock operates without springs, meaning the solid metal bolt must be physically thrown using a key or an internal thumbturn. Once extended deep into the door frame, the bolt is locked completely rigid. We specialise in deadlock/deadbolt installation, so you avail benefits such as:
Immunity to Shimming
Because the mechanism lacks a spring, it cannot be forced back or slipped open using plastic cards or specialised tools.
Deep Structural Reinforcement
The deadbolt throws directly into the core timber frame, creating a resilient physical barrier against blunt structural force.
Visual Deterrent
High-security hardware signals to opportunists that a quiet, rapid breach is impossible, forcing them to move on. Recognising when an existing deadbolt requires professional replacement is also crucial.
We also provide deadlock replacement services. Look for the following signs to understand if a new installation is needed:
- Internal pin tumblers are wearing down, making the key difficult to turn.
- Structural force from an attempted break-in that fractures mounting screws or bends the internal bolt actuator.
Our complimentary on-site home security assessment evaluates frame stability and hinge strength during every visit.
Frequently Asked Questions
What is the technical difference between a rim deadlock and a morticed deadlock?
A rim deadlock is surface-mounted directly onto the inside face of the door and frame, making it an excellent choice for heritage or period homes with thin timber doors that cannot tolerate deep internal drilling. A morticed deadlock is completely inset into a pocket carved directly inside the core of the door edge, concealing the entire body of the lock within the woodwork for a seamless, highly secure aesthetic that offers superior resistance against structural leverage.
Do I need to purchase a completely new lock assembly if I just want to change who has access to my home?
No, a full replacement is often unnecessary if the physical lock body and cylinders are in good structural condition. If you have moved into a new home or lost a set of keys, we can perform a precision rekeying service instead. We disassemble the existing lock cylinder and replace the internal pin configurations so that old keys cease to function, cutting a completely new master set for a fraction of the cost of replacing the entire deadlock unit.
Can a heavy-duty deadlock be retrofitted onto a modern aluminium-framed sliding glass patio door?
Yes. Standard swing-door deadlocks will not fit narrow aluminium frames, but we stock specialised narrow-stile patio deadlocks specifically engineered for metal profiles. These units utilise a hooked or interlocking bolt mechanism rather than a straight throw, preventing intruders from physically lifting the sliding glass panel out of its tracks, a very common vulnerability in modern architectural layouts.
How do the recent Victorian rental minimum standards impact deadlock obligations for landlords?
Under Victorian residential tenancies regulations, landlords are legally obligated to ensure all external entry doors to a rental property are fitted with a functioning lock that can be opened with a key from the outside and features a deadbolt or deadlock mechanism. If your rental property currently relies on basic key-in-knob locks or broken hardware, we can install compliant, heavy-duty deadbolts that protect your tenants while keeping your investment fully aligned with state housing laws.
