As smart home technology becomes increasingly popular in Australia, more and more households are considering upgrading their traditional door locks to smart locks. Whether for owner-occupied homes, investment properties, or short-term rentals, smart locks are widely welcomed for their enhanced security, convenience, and modern appeal.
However, a smart lock is not a product that can simply be purchased and installed without preparation. Australia’s housing structures, door standards, and living habits differ significantly from those in other markets. Installing a smart lock without understanding these key factors can easily lead to installation failure, limited functionality, poor user experience, or even security risks.
Therefore, before installing a smart lock, there are five essential things you must understand in advance. This article takes real Australian conditions into account and systematically explains these five key points to help you make the right decision.
First Thing: Is Your Door Really Suitable for a Smart Lock?
In Australia, not every door is naturally suitable for installing a smart lock. The door’s material, thickness, internal structure, and lock specifications all directly affect installation feasibility. Determining whether your door is compatible is the first and most critical step in ensuring both usability and security.
Unlike traditional mechanical locks, smart locks have specific requirements for door material, thickness, structure, and existing locking systems. Installing one without proper assessment may result in poor compatibility, restricted features, or even damage to the door itself.
The first step is to identify your door type. Common residential doors in Australia include solid timber doors, engineered timber doors, steel doors, and aluminium-framed glass doors. Among these, solid timber doors and steel doors are generally the most suitable for smart lock installation. Fully glass doors or doors with very narrow frames may not provide sufficient space to accommodate the lock body and often require special accessories—or are not recommended for installation at all.
Next, measure the door thickness. Most smart locks are designed to fit doors with a thickness between 35 mm and 50 mm. Doors outside this range may require customised spacers or may not be compatible.
1. Common Door Types in Australia
In Australian residential properties, the most common door types include:
- · Solid Timber Doors
- · Engineered Timber Doors
- · Steel Doors
- · Security Screen Doors / Security Doors
Among these:
- · Solid timber and engineered timber doors are the most ideal options for smart lock installation
- · Steel doors can also be suitable, provided thickness and internal space requirements are met
- · Security screen doors are generally not recommended for complex smart locks and are better suited to basic electronic locks or used in combination with a main entry door
2. Door Thickness and Cut-Out Dimensions
Most mainstream smart locks have clear requirements for door thickness, typically within the range of:
35 mm – 60 mm (some premium models support thicker doors)
In addition, you should confirm:
- · Whether a standard lock cut-out already exists
- · Whether there is sufficient internal space to accommodate the lock body, motor, and battery compartment
Important note:
Some older Australian homes have thinner doors or irregular internal structures, making them unsuitable for direct smart lock replacement. Accurate measurement is essential before purchase.
From another perspective, power supply and long-term maintenance should also be considered. While some high-end models support backup batteries or solar charging, limited internal space and frequent door usage can still affect battery life. For this reason, it is recommended to take clear photos of the front and back of the door, the lock cut-out details, and the door edge, and consult a professional installer with local Australian experience before purchasing.
AT Smart Lock offers a complimentary pre-installation assessment service to help accurately determine compatibility, avoiding returns, modifications, or potential security issues caused by unsuitable door types—ensuring you make the right choice once and enjoy long-term peace of mind.
Second Thing: Does the Lock Mechanism Meet Australian Standards? (Critically Important)
This is one of the most commonly overlooked factors—and also the one most likely to cause problems later. When installing a smart lock in Australia, confirming that the lock mechanism complies with local standards is essential. It affects not only installation compatibility, but can also have direct implications for home insurance validity and security compliance.
Most Australian residential properties use locking systems that comply with AS 4145.2, the Australian Standard for locksets. The most common types include mortice locks and Euro cylinder systems, rather than the wide “Chinese-style lock bodies” (often over 60 mm in width) commonly found in some Asian markets.
To determine whether your existing lock mechanism is compliant, start by examining the edge of the door. If the lock body is recessed into the door leaf and uses a replaceable cylindrical lock core, commonly seen in apartments and modern homes, it is most likely a Euro cylinder system. If the lock is a one-piece, elongated body incorporating both a latch bolt and a deadbolt, it is typically a mortice lock.
Next, measure the lock dimensions. Standard Australian mortice lock bodies are generally 160–180 mm in length, with a thickness of no more than 30 mm. By contrast, many imported smart locks come pre-fitted with 60 mm wide lock bodies designed for other markets, which cannot be directly replaced. Forced modifications can damage the door structure and may even result in insurance claims being rejected.
The most reliable approach is to check whether the existing lock carries AS 4145.2 certification, or to have a licensed locksmith conduct an on-site assessment.
1. Common Lock Mechanism Standards in Australia
Australian residential doors typically use the following lock mechanisms:
- · 60 mm Backset Mortice Lock
- · 70 mm Backset Mortice Lock
- · Deadbolt (independent bolt system)
If the smart lock’s mechanism does not match the existing lock specifications, the following issues may arise:
- · Additional drilling or re-cutting of the door
- · Structural damage to the door
- · Misaligned latch or bolt, compromising security
- · Installation failure or significantly increased costs
2. Not All “Overseas Smart Locks” Are Suitable for Australia
Some smart locks designed for other markets may have:
- · Lock body dimensions that do not meet Australian standards
- · Insufficient latch or bolt length
- · Incompatibility with local door frames and strike plates
For this reason, when choosing a smart lock in Australia, it is essential to confirm that it either uses an Australian-standard lock mechanism or explicitly supports customisation for Australian door types.
Third Thing: What Unlocking Method Do You Actually Need?
When selecting a smart lock, many consumers are easily influenced by the idea that “the more features, the better.” In real-world use, however, the right unlocking methods matter far more than the number of features.
Many buyers are drawn to multiple unlocking options but overlook the most important question: which methods truly suit your household’s daily habits and usage scenarios? Smart technology should adapt to your lifestyle—not complicate it.
For example, in households with elderly family members or young children, fingerprints may wear easily or be difficult to recognise. In such cases, palm vein recognition or 3D facial recognition can be more reliable and hygienic than traditional fingerprint scanning. Users who frequently carry shopping bags or hold children when entering the home often value automatic proximity unlocking or remote temporary access codes. Those living alone or prioritising privacy may rely more heavily on mobile app control and real-time visitor notifications.
Australia’s variable climate also plays a role. Rain, strong sunlight, and changing light conditions can affect optical fingerprint sensors or 2D facial recognition systems. Smart locks equipped with structured-light 3D facial recognition or live palm vein technology offer more stable performance in these environments.
Backup options are equally important. In the event of battery depletion or network failure, does the lock retain a mechanical key override or support Type-C emergency power supply?
True intelligence is not about stacking technologies—it is about integrating them seamlessly into everyday life. AT Smart Lock recommends selecting one or two primary unlocking methods based on your household composition, daily routines, door environment, and security priorities, with additional methods serving as backups. This approach delivers convenience while avoiding unnecessary complexity or potential security risks.
Choosing the right unlocking method is the true starting point of smart living.

- · Households with elderly residents: Simple PIN codes or access cards for ease of use
Fourth Thing: Have You Considered the Power Supply and Ongoing Maintenance?
A smart lock is not a “set it and forget it” product—it is a long-term electronic device designed for daily use. When choosing a smart lock, many consumers focus on appearance and unlocking methods, while overlooking a critical factor: power supply and ongoing maintenance.
As a device that operates 24/7, a smart lock’s battery life, charging convenience, and contingency measures directly determine the long-term user experience. Most smart locks on the market are powered by 4–8 AA batteries or lithium batteries, with battery life ranging from three months to one year. However, frequent use of features such as facial recognition or remote video functions can significantly accelerate power consumption. Without an emergency power solution, a depleted battery could leave users locked outside their own home.
An ideal smart lock should include low-battery alerts, a Type-C emergency power interface, and in some advanced models, solar-assisted charging (such as the Lockin Veno series), which is particularly suitable for Australia’s abundant sunlight. Battery compartment design also plays a crucial role in maintenance. Poor-quality products may suffer from loose batteries or unstable contact, while premium locks use anti-drop dual battery slots or modular power systems to ensure stable operation.
Ongoing maintenance is equally important. Does the brand offer local warranty support? Can the software be updated remotely? Are replacement components—such as battery covers or circuit boards—readily available? In a country as geographically vast as Australia, choosing a brand with local warehousing, professional installation teams, and fast after-sales response can significantly reduce maintenance costs and waiting times.
1. Common Power Supply Options
In the Australian market, most mainstream smart locks use:
- · AA batteries (most common)
- · Lithium batteries (built-in or replaceable)
Typical battery life:
- · Normal household use: 6–12 months
- · High-frequency use: 3–6 months
2. Key Details You Must Pay Attention To
- · Is there a low-battery warning system?
- · Does the lock support USB or Type-C emergency power?
- · Are the batteries easy to replace?
- · Is local after-sales support available for parts replacement?
Important reminder:
Australian households generally prioritise stability and durability over frequent charging or maintenance. Choosing a proven, mature solution is especially important.
Fifth Thing: Installation and After-Sales Service Matter More Than You Think
Many people believe that “once the lock is purchased, installation is a minor detail.” In Australia, however, installation quality and after-sales service often determine the upper limit of the user experience.
When purchasing a smart lock, many consumers focus only on features and price, underestimating the importance of installation and support. Yet this is exactly what determines whether a smart lock becomes a reliable home guardian or a source of ongoing frustration.
Australia’s residential doors vary widely, and lock standards are strict (such as AS 4145.2). Installation by non-professionals can result in minor issues like door damage or abnormal lock noise, or serious problems such as compromised security structures and potential insurance implications. A common scenario is users attempting self-installation only to encounter latch rebound issues, motor jamming, or app pairing failures—often caused by improper door gap adjustment, incompatible lock bodies, or incorrect wiring.
Professional installation teams not only assess door compatibility accurately, but also fine-tune latch orientation, calibrate sensors, optimise Wi-Fi connectivity, and ensure that all security functions are properly activated. Equally critical is localised after-sales support. When software issues, battery abnormalities, or component damage occur, can you receive timely technical assistance or on-site service? Overseas brands without local Australian warehouses or certified technicians often require weeks for repairs, severely impacting the user experience.
1. Do You Need Professional Installation?
Professional installation is strongly recommended in the following situations:
- · The door is a solid timber door or a high-value custom door
- · Lock mechanism specifications need to be changed
- · The door frame structure is complex
- · The smart lock is a high-end or premium model
Professional installation helps prevent:
- · Damage to the door
- · Loose or unstable lock mechanisms
- · Reduced security performance
2. Is Local After-Sales Support Available in Australia?
When selecting a smart lock, be sure to confirm:
- · Whether the brand has local Australian warehousing
- · Whether local technical support is available
- · Whether the product complies with Australian safety standards
- · Whether clear warranty and service policies are provided
For long-term security products, local service is far more important than a low purchase price.
Final Thoughts
Choosing the right smart lock is not just about selecting a high-tech product—it is about building a secure, convenient, and reliable daily safeguard for your family. In Australia’s diverse residential landscape, from traditional timber doors to modern steel doors, and from standalone houses to apartment units, every door presents unique structural and security requirements.
A thorough pre-installation assessment is never an unnecessary step; it is the key to ensuring stable, long-term performance. Ignoring door compatibility, lock standards, or local compliance can lead not only to installation failure but also to hidden security risks. Likewise, overlooking usage habits and power supply considerations can turn a device designed to simplify life into a daily inconvenience.
Before installing a smart lock in Australia, always remember these five essential considerations:
1. Whether the door type and structure are suitable
2. Whether the lock mechanism complies with Australian standards
3. Whether the unlocking methods truly match your usage scenarios
4. Whether power supply and maintenance are reliable and hassle-free
5. Whether professional installation and local after-sales support are available
More importantly, true intelligence goes beyond connectivity or facial recognition. It lies in having a professional team behind the product—one that provides installation services compliant with Australian standards and responsive local support.
