Windows are an important part of home security, but they are sometimes overlooked when homeowners upgrade their doors and entry points. A strong front door lock is useful, but an unsecured or poorly fitted window can still create a weak point around the home.
For Perth homeowners, choosing the right window lock means considering more than just the lock itself. The type of window, its location, how often it is opened, ventilation requirements, ease of use and the level of security you need can all influence which option is most suitable.
So, what are the best window locks for Perth homes?
For many homes, keyed window locks, sliding window locks, casement window locks, sash locks and quality security-screen solutions can all provide effective protection when correctly matched to the window. The best choice depends on your window style and the level of security you want.
At Sheehan Locksmiths Perth, we understand that every property has different window designs and security requirements. This guide explains the main types of window locks available and what Perth homeowners should consider before installing or replacing them.
Why Window Locks Matter for Home Security
A window is designed to provide ventilation, natural light and easy access to the outdoors. However, when it is left unsecured, it can become a potential entry point.
A proper window lock helps keep the window closed and prevents it from being opened from outside. In Western Australia, this is also relevant to rental properties because minimum security requirements state that windows must have a lock or another suitable mechanism that prevents them from being opened from outside. The rules do not generally require every window lock to be key-operated.
Good window security can therefore provide several benefits:
- Helps prevent unwanted access through windows
- Adds another layer of residential security
- Keeps windows firmly closed when the property is unattended
- Provides greater control over ground-floor and accessible windows
- Can improve security without replacing the entire window
- Gives homeowners more confidence at night or while travelling
However, a window lock should not be selected based on appearance alone. The lock needs to work properly with the existing window hardware and frame.
The Best Window Locks for Perth Homes
There is no single window lock that is ideal for every Perth property. Different window designs require different locking mechanisms.
Here are some of the most common options to consider.
1. Keyed Window Locks
Keyed window locks are one of the most popular choices when homeowners want an additional level of physical security.
These locks use a key to operate the locking mechanism. Depending on the design, they can be installed on different types of windows and can provide a stronger barrier than a basic latch.
Best for:
- Ground-floor windows
- Windows close to external pathways
- Easily accessible windows
- Homeowners wanting additional security
- Properties that are regularly left unattended
One advantage of keyed window locks is that they provide a clear locking mechanism that cannot simply be released by operating a standard handle or latch.
However, homeowners should also think about emergency access. A window that is permanently locked may be difficult to open quickly if it is needed as an exit during an emergency. This is why professional installation and correct hardware selection are important.
2. Sliding Window Locks
Sliding windows are common in Australian homes and require locks designed specifically for their movement.
A sliding window lock prevents the movable section from sliding along its track. Depending on the window design, homeowners may choose a keyed lock, latch-style lock or another compatible locking device.
Sliding window locks can be particularly useful for windows located on the ground floor or near areas that are easily accessible from outside.
When choosing a sliding window lock, make sure the lock is compatible with the window frame and track. A poorly fitted lock may not provide the level of security expected.
3. Casement Window Locks
Casement windows open outward using hinges and are often operated with a handle, winder or locking mechanism.
Because the opening mechanism is different from a sliding window, casement windows require compatible hardware.
A good casement window lock should hold the window securely against the frame while allowing normal operation when unlocked.
For older Perth properties, replacing worn or damaged casement hardware can sometimes improve window security without requiring the entire window to be replaced.
A locksmith can inspect the existing mechanism and determine whether the problem is the lock, handle, latch, winder or another part of the hardware.
4. Sash Window Locks
Traditional sash windows move vertically rather than sliding horizontally. They can be found in older homes and character properties.
Sash locks are designed to secure the two sections of the window together and prevent unwanted movement.
For heritage-style homes, choosing a lock that provides security while complementing the appearance of the original window can be important.
It is worth avoiding a one-size-fits-all approach because older window frames can have different dimensions and hardware configurations.
5. Lockable Window Handles
Some modern windows use handles that incorporate a locking mechanism.
These can provide a clean appearance because the locking function is integrated into the handle rather than being installed as a separate device.
Lockable handles can be suitable for homeowners who want practical security without adding bulky hardware to the window frame.
The key consideration is whether the existing window can accept the replacement handle and whether the locking points are working correctly.
6. Louvre Window Locks
Louvre windows, sometimes called jalousie windows, consist of multiple glass blades that tilt open and closed.
Because the individual blades operate together, louvre windows require a suitable mechanism to secure them.
Western Australia’s rental security guidance specifically states that louvre windows must have a working lock, or another mechanism that locks the lever in the fully closed position.If you have older louvre windows and the existing mechanism is loose, damaged or ineffective, professional inspection can help determine whether the hardware can be repaired or should be replaced.
7. Window Security Screens
Although technically different from a conventional window lock, a properly designed security screen can provide another layer of protection.
Security screens can allow homeowners to ventilate their property while creating a physical barrier between the interior and exterior.
For some properties, particularly homes with frequently opened windows, a security screen may complement the existing window lock.
Western Australian guidance also recognises compliant security screens as an alternative in certain rental security situations.However, not every flyscreen provides the same level of security. A standard insect screen should not automatically be considered a security barrier.
Which Window Lock Is Best for Your Perth Home?
The right choice depends on several factors.
Consider the Window Type
Start by identifying whether you have:
- Sliding windows
- Casement windows
- Sash windows
- Louvre windows
- Awning windows
- Aluminium windows
- Timber windows
The correct lock needs to match the design and movement of the window.
Consider Window Accessibility
A ground-floor window that opens onto a backyard, driveway or secluded side passage may require more attention than a window several metres above ground level.
Western Australia’s minimum rental security guidance recognises that windows which cannot be easily accessed from outside may be treated differently from accessible windows.For homeowners, however, accessibility should still be considered as part of an overall security assessment.
Think About How You Use the Window
A bedroom window that is rarely opened may have different requirements from a kitchen or living-room window that is opened every day for ventilation.
If you frequently open and close a window, the lock should be convenient enough that you will actually use it.
A security device that is frustrating to operate may eventually be left unlocked.
Consider Emergency Exit Requirements
Security should not prevent safe escape.
Before installing keyed locks on windows, consider whether the window could be required as an emergency exit. A professional locksmith can help identify a suitable solution that balances security and practical access.
This is particularly important for bedrooms and other areas where windows may play a role in emergency evacuation.
Are Keyed Window Locks Better Than Standard Latches?
Not necessarily.
A keyed window lock can provide an additional layer of control, but a standard latch may be appropriate for some situations.
In Western Australia, minimum rental requirements do not state that every window must have a keyed lock. The requirement is generally that the window is secured against being opened from outside, with a working latch, closer or lock depending on the circumstances.
The better question is:
Does the locking mechanism suit the window, property and security requirements?
For a highly accessible ground-floor window, a homeowner may prefer a keyed option. For another window, a properly functioning integrated lock may be perfectly suitable.
What Makes a Good Window Lock?
When comparing window locks, look beyond the price.
A good window lock should ideally provide:
Strong Physical Security
The lock should securely hold the window in its closed position and be properly attached to the frame.
Correct Compatibility
The mechanism needs to suit the window’s construction and opening style.
Reliable Operation
A lock that sticks, jams or becomes difficult to operate can quickly become a problem.
Quality Installation
Even a good lock can perform poorly if it is incorrectly fitted.
Practical Everyday Use
The lock should be simple enough for household members to operate correctly.
Appropriate Emergency Access
Security upgrades should be planned with safe exit and ventilation requirements in mind.
When Should You Replace Your Window Locks?
You may need new window locks if:
- The lock is broken
- The key is missing
- The mechanism is difficult to operate
- The window does not close securely
- The lock is loose
- The window can be opened from outside
- The existing hardware is badly worn
- You have recently moved into an older property
- You are upgrading the home’s overall security
A broken or rusted lock should not simply be ignored. Western Australian Consumer Protection guidance lists broken or rusted locks among security maintenance issues that may require attention.
Window Locks for Perth Rental Properties
If you are renting a property in Perth, window security is particularly important because Western Australia has minimum security requirements for rental homes.
Consumer Protection WA states that windows must be fitted with a lock that prevents them from being opened from outside. Windows do not necessarily need keyed locks, and compliant security screens can affect whether a separate window lock is required.
Tenants should also understand that installing additional security or changing locks may require landlord permission in many circumstances. There are specific exceptions and rules, so tenants should check the current Western Australian requirements before making changes.
If a rental home’s existing window locks are damaged or do not provide the required level of security, raising the issue with the property manager or landlord is an appropriate first step.
Should You Install Window Locks Yourself?
Some basic window locks may look simple to install, but professional installation can be worthwhile when security is the main objective.
Incorrect positioning can affect how effectively the lock holds the window. Drilling into the wrong location can also damage the frame or interfere with the window’s normal operation.
A professional locksmith can assess:
- Window type
- Existing hardware
- Frame condition
- Lock placement
- Accessibility from outside
- Key requirements
- Everyday operation
- Existing security measures
This can be particularly useful when several different window styles are present throughout the same Perth home.
A Complete Approach to Window Security
Window locks should be considered as one part of a wider home-security strategy.
For better protection, homeowners can also look at:
- Strong exterior door locks
- Security doors and screens
- Adequate exterior lighting
- Alarm systems
- CCTV cameras
- Secure sliding doors
- Garage security
- Regular maintenance of locks and frames
The objective is not simply to install the most expensive lock available. Effective security comes from identifying vulnerable points and choosing suitable solutions for each one.
Why Professional Window Lock Installation Makes Sense
Every home is different. A lock that works perfectly on one window may be unsuitable for another.
At Sheehan Locksmiths Perth, a professional assessment can help homeowners understand which type of window lock is appropriate for their existing windows.
Rather than replacing windows unnecessarily, it may be possible to repair existing hardware or upgrade the locking mechanism.
Professional installation can also help ensure that the lock operates smoothly and that the window remains practical for everyday use.
If you are unsure which window lock is right for your Perth property, getting the window and existing hardware assessed before purchasing a lock can help you avoid choosing the wrong product.
Final Thoughts: What Are the Best Window Locks for Perth Homes?
The best window locks for Perth homes depend on the window design, accessibility, existing hardware and the level of security required.
Keyed window locks can be a strong choice for accessible windows where additional security is desired. Sliding window locks work well with horizontal sliding designs, while casement and sash locks are better suited to their respective window styles. Louvre window locks are particularly important for securing louvre-style windows, and security screens can provide another layer of protection while allowing ventilation.
For Perth homeowners, the most important point is not simply choosing the strongest-looking lock. The lock needs to be compatible with the window, correctly installed, reliable in everyday use and appropriate for the property’s security requirements.
If your existing window locks are damaged, outdated, missing keys or no longer securing the window properly, consider having them inspected by a qualified locksmith. A professional assessment can help you choose a practical security solution without unnecessary replacement of the entire window.
