How common is lock snapping in Australia?

Lock snapping is becoming a real worry for Australian homeowners, especially if you've got euro cylinder locks on your uPVC or composite doors. The thing is, we don't have specific Australian data that tracks lock snapping incidents yet, but we can look at the bigger picture of home break-ins to get a sense of what's happening.

In 2023-24, about 2.0% of Australian households (that's 206,600 homes) had someone break in. This was actually up from the record low of 1.7% back in 2020-21, when everyone was stuck at home during COVID lockdowns.

Now, lock snapping goes after euro cylinder locks specifically. These are the locks you'll find on most modern uPVC and composite doors, and they're pretty common in newer Australian homes. The problem is, if you've got a basic euro cylinder without proper security features, it's a sitting duck for this kind of attack.

Looking at data from the UK, where they track this stuff more closely, lock snapping was behind 8.32% of burglaries in 2019. That might not sound like heaps, but it's still significant. Interestingly, this was down from a peak of 15.87% back in 2011, mainly because they started making better locks.

In Australia, you're more likely to see this in urban areas and places with lots of newer housing developments. Think apartment complexes, modern suburbs, anywhere there's lots of uPVC and composite doors. That's where the risk is higher.

When you compare it to other ways people break in, about 40% of attempted break-ins show signs of door or window damage. Traditional forced entry is still the most common method, but lock snapping is sneaky because it might not leave obvious damage until the lock's already busted.

‍

What is lock snapping?

Lock snapping is basically a brute force way of attacking euro cylinder locks. What happens is someone breaks the cylinder barrel in half to get at the locking mechanism inside. It works because standard euro cylinders have a weak spot right in the middle where they can be snapped.

Here's how it works: someone applies serious force to the bit of the euro cylinder that sticks out from your door. With basic euro cylinders, this can happen in just 5 to 10 seconds. Once they snap the front part off, the door lock mechanism is exposed, and then they just use a screwdriver to turn it and unlock your door.

The scary thing is how simple it is. Burglars don't need fancy tools or special skills. They might use mole grips, pliers, or even just an adjustable spanner to grab hold of the cylinder and twist or pull it until it breaks. Some will even use a hammer. Basically, anything that can grip the cylinder and apply enough force will do the job.

The process is pretty straightforward: grab the cylinder that pokes out from your door handle, apply force to snap it, and once the outer bit breaks away, you can access the internal mechanism with something as simple as a screwdriver.

This attack works particularly well on older or basic euro cylinders that don't have anti-snap features built in. The good news is that modern high-security cylinders have things like sacrificial break points and internal security features that stop this kind of attack from working.

You'll mainly find euro cylinder locks on uPVC doors, composite doors, and some newer timber doors that have multi-point locking systems. These are getting more and more common in Australian homes, especially in new builds and apartment blocks.

‍

How prevalent is lock snapping in major cities in Australia?

The reality is, lock snapping isn't evenly spread across Australia's major cities. It really comes down to where you'll find the most euro cylinder locks, and that's usually in areas with lots of newer housing and apartment developments.

Melbourne's probably dealing with the biggest challenge here. They had 25,915 home burglaries in 2024, which was up 10.7% from the year before. The thing is, Melbourne's got heaps of modern apartments and townhouses, and these places almost always use euro cylinder locks. So while we don't have exact lock snapping numbers, the potential is definitely there.

Brisbane's seeing its fair share of trouble too. Southeast Queensland had 44,900 break ins in 2021 to 2022, affecting 2.2% of households. With all the new development happening around Brisbane, there's more and more uPVC and composite doors going in, which means more euro cylinders for criminals to target.

Sydney's actually been doing better on the break in front overall. NSW has seen break and enter offences dropping by more than half since 2000, which is pretty impressive. But here's the thing – Sydney's still got massive urban density and loads of newer apartment blocks, so the risk is still there in those areas.

Adelaide and Perth have lower break in rates generally, but their newer suburbs and apartment developments aren't immune. The numbers might be smaller because the cities are smaller, but anywhere you've got these modern lock types, you've got potential risk.

What it really boils down to is the type of housing. If you're looking at newer developments, high density areas, and modern construction, that's where you'll find euro cylinder locks. And that's where lock snapping becomes a real possibility.

‍

How often does lock snapping occur in Sydney?

Here's the frustrating bit! NSW Police don't actually track lock snapping as a separate category, so we're working with educated guesses based on what we do know about break ins and housing types in Sydney.

What we do know is that NSW has been doing pretty well with break ins overall. The numbers have been dropping for more than a decade, falling by over half since they peaked in 2000. That's genuinely good news. But Sydney's a different beast because of how dense it is and how many newer apartment buildings there are.

Most break ins in NSW happen during the day, between 6am and 6pm, when people are typically out. This timing would probably be the same for lock snapping attempts, since the whole point is that it's quick and doesn't make much noise.

If we look at what happens overseas in places with lots of euro cylinder locks, lock snapping usually accounts for somewhere between 8% and 15% of burglaries. So in Sydney's newer neighbourhoods with lots of modern apartments and townhouses, you might see similar rates.

The areas that would be most at risk are probably the inner city apartment blocks, newer suburban developments, and townhouse complexes. Basically, anywhere they've installed euro cylinder locks as standard. Places like the newer developments in Western Sydney, or the high rise apartments around the CBD and inner suburbs.

Without NSW Police specifically tracking how burglars are getting in, it's hard to say exactly how common lock snapping is. But given Sydney's housing mix and the number of euro cylinders that must be out there, it's probably happening more than we realise, especially in those areas with concentrated modern housing.

‍

Is lock snapping more common in specific Australian states?

While specific lock snapping data isn't tracked separately by state police forces, we can look at where this type of attack would be most likely based on housing patterns and break-in statistics across different states.

Victoria probably faces the highest potential risk for lock snapping incidents. The state recorded 25,915 home burglaries in 2024, and Melbourne's dense urban environment has loads of modern apartment buildings and townhouses where euro cylinder locks are standard. Victoria's crime statistics show that "Door" was the most common entry point for residential burglaries at 40.9%, with "Forced/Broke Door" being the top method at 23.6% of all entry attempts.

Queensland comes in second for potential lock snapping vulnerability. Brisbane and surrounding areas experienced 44,900 break-ins affecting 2.2% of households in 2021 to 2022. The rapid development in Southeast Queensland means more new housing with euro cylinder locks. The state saw 16.4% of all Australian burglaries in 2017, giving criminals more opportunities to learn and use lock snapping techniques.

New South Wales actually has lower overall break-in rates these days, with numbers dropping by more than half since 2000. But Sydney's massive population and concentration of newer apartments still create plenty of potential targets. The key difference is that NSW seems to be getting better at preventing break-ins generally.

Western Australia and South Australia have lower absolute numbers simply because their populations are smaller. WA had 36,400 attempted break-ins reported in 2017, while SA had 15,800. However, both states are seeing growth in modern housing developments where euro cylinder locks are becoming more common.

The main factors behind these regional variations are pretty straightforward. States with more new construction, higher population density, and lots of apartment living tend to have more euro cylinder locks installed. That's where lock snapping becomes a real possibility. Also, areas with higher overall crime rates give criminals more chances to discover and practice these techniques.

Tasmania and the Northern Territory have the lowest risk simply because they have smaller populations and less modern high-density housing. But even there, newer developments aren't immune if they're using euro cylinder locks.

‍

How does lock snapping in Australia compare to other types of break-ins?

When you look at how criminals actually get into Australian homes, lock snapping is just one method among many, and it's probably not as common as you might think.

The big picture shows that unlocked doors are still the number one way burglars get in. About 32% of break-ins happen through doors that weren't even locked in the first place. That's nearly one in three burglaries that could have been prevented just by turning a key. It's pretty sobering when you think about it.

Forced entry through doors comes in second at around 23.6% of break-ins, according to Victorian crime statistics. This is where lock snapping would fit in, but it's only a subset of that forced door entry category. Based on international data, lock snapping probably accounts for somewhere between 8% to 15% of burglaries in areas with lots of euro cylinder locks.

Windows are another major entry point, making up about 17.1% of break-ins. Forced or broken windows account for a significant chunk of these. Then you've got unlocked windows, which is similar to the unlocked door problem but happens less frequently.

What's interesting is that about 11.9% of break-ins show no signs of forced entry at all. These are cases where criminals used keys, found unlocked access, or had some other way to get in without breaking anything.

Other methods like garage doors account for about 9% of break-ins. Rear and back entrances make up another 14.8% of entry points, while front doors account for 8.4%.

So if we're being realistic about the numbers, lock snapping probably represents somewhere between 2% to 4% of all break-ins in areas where euro cylinder locks are common. That might not sound like much, but when you consider there were over 200,000 break-ins across Australia in recent years, even a small percentage means thousands of homes could be at risk.

The key takeaway is that lock snapping is just one piece of a much bigger puzzle. Yes, it's a real threat if you have euro cylinder locks, but you're statistically more likely to be burgled through an unlocked door or window than through lock snapping. The best approach is comprehensive security that addresses all these entry methods, not just focusing on one particular technique.

‍

Is lock snapping more common than window break-ins in Sydney?

When you compare lock snapping to window break-ins in Sydney, window attacks are definitely happening more often right now.

Window break-ins make up about 17.1% of all the ways criminals get into Australian homes, according to national crime stats. That's a pretty big chunk, making windows the second most popular entry point after doors.

Lock snapping, on the other hand, probably accounts for somewhere between 2% to 4% of break-ins in Sydney areas where you'll find lots of euro cylinder locks. We don't have exact Sydney numbers on lock snapping, but this estimate comes from looking at international patterns where lock snapping hits 8% to 15% of burglaries in areas packed with euro cylinder locks. The thing is, it only affects homes that actually have these specific lock types.

Here's how they stack up:

• Window break-ins: 17.1% of all ways criminals get into homes
• Lock snapping: 2-4% estimated for Sydney (this is part of that 23.6% forced door entry category)

But here's where it gets interesting - the risk really depends on what type of home you've got. If you're in a traditional Sydney house with older windows and standard deadlocks, you're more likely to face window break-in risks. But if you're in a modern apartment, townhouse, or newer development with euro cylinder locks, you might face higher lock snapping risks. The flip side is these newer places often have stronger, double-glazed windows that are much harder to smash.

Window break-ins are more common in Sydney because:

• Every property has windows, but euro cylinders are mostly just in newer developments
• Heaps of Sydney homes still have older, easier-to-break window hardware
• Summer months see more window break-ins when people leave windows open for fresh air
• Breaking windows only needs basic tools that most criminals already carry

Lock snapping might be less common overall, but it's a concentrated risk in specific Sydney areas with lots of modern housing, especially inner-city apartments and newer suburban developments where euro cylinder locks are the norm.

For Sydney homeowners, this means you should definitely prioritise window security since it's the bigger statistical threat. But if you're living somewhere with euro cylinder locks, don't ignore lock snapping prevention as part of your overall home security plan.

‍

How aware are Australians of lock snapping risks?

The honest answer is that most Australians have pretty much no idea about lock snapping risks. This creates a massive security blind spot, especially when more and more homes are getting these vulnerable euro cylinder locks.

The 2024 Budget Direct Home Burglary Survey asked 1,003 Australians about their security habits, and the results show some worrying gaps. While 55% of people had deadlocks installed, this suggests loads of Australians don't actually know about different lock types and how secure they really are. Even more telling, only 43% of people who'd been burgled bothered to upgrade or change their locks afterward. That tells you most people don't understand how criminals specifically target their lock types.

There's a huge knowledge gap when it comes to euro cylinder vulnerabilities. Most Australians with uPVC or composite doors that have euro cylinder locks have absolutely no clue these locks can be snapped in seconds with basic tools. This is really problematic because these door types are popping up everywhere in new Australian developments.

The locksmith industry keeps saying public education is pretty much non-existent. Professional associations report that homeowners are constantly surprised to learn their locks might be vulnerable to snapping, even though this attack method is well-known internationally. When lock snapping does happen, it usually comes as a complete shock to victims who thought their modern doors were bulletproof.

Security surveys show Australians love the security measures they can actually see rather than focusing on lock quality. That same Budget Direct survey found 50% of people installed security screens, 40% had security cameras, and 38% used sensor lights. But there's basically no evidence that Australians are specifically upgrading to anti-snap cylinder locks or even bothering to check their lock security ratings.

Awareness probably varies depending on where you live. Areas with established locksmith communities and higher crime rates might know more about lock snapping risks. But lots of suburban areas with newer developments probably have lower awareness levels, despite having more of these vulnerable euro cylinder locks.

The insurance industry isn't really pushing awareness either. Unlike some overseas markets where insurers specifically demand anti-snap locks for coverage, Australian home insurance policies generally don't care what type of locks you have. This means homeowners don't have much incentive to learn about lock security standards.

Social media and news coverage of lock snapping is pretty minimal compared to other security topics. Most Australians hear about break-ins through traditional forced entry stories rather than specific techniques like lock snapping, which might not even leave obvious damage until someone actually examines the lock mechanism.

This awareness gap is both a problem and an opportunity. While low awareness leaves heaps of properties vulnerable, it also means there's massive potential for public education campaigns and professional security assessments to make a real difference in home security across Australia.

‍

What measures are taken by Australians to prevent lock snapping?

The reality is, most Australians aren't doing anything specific to prevent lock snapping because they don't even know it's a thing. But some of the general security stuff people are doing does help protect against it, even if that wasn't the plan.

Here's what Australians are actually doing for security:

• Deadlocks: Installed in 55% of households, but here's the catch. Most people think having a deadlock means they're sorted, but if you've also got a vulnerable euro cylinder on the same door, that deadlock won't help much when someone snaps your euro cylinder.
• Security screens: Used by 50% of households and they're actually brilliant against lock snapping. If you've got a proper security screen, criminals can't even get to your door lock to snap it in the first place. Problem solved.
• Security cameras: Found in 40% of households, and while they don't stop lock snapping directly, they definitely make criminals think twice since snapping takes time and nobody wants to be caught on camera.
• Sensor lights: Installed by 38% of households, these create extra risk for criminals who prefer to work in darkness and need time to snap locks without being spotted.
• CCTV and alarm systems: Getting more common, especially in the cities. These add real risk for criminals since lock snapping usually takes 30 seconds to 2 minutes, which is plenty of time to get caught.
• Door and frame reinforcement: More people are doing this these days, though usually for general security rather than specifically thinking about lock snapping.

But here's what Australians aren't doing, and really should be:

• Anti-snap lock upgrades: Hardly anyone does this. Most Australians with euro cylinder locks don't even know these upgrades exist. It's not like anyone's talking about it in the mainstream.
• Professional lock assessments: Pretty much unheard of. In the UK, people know about lock security standards, but most Australians never get their locks properly checked by an expert.
• SS312 Diamond or TS007 3-star rated cylinders: These might as well be written in a foreign language for most Australian consumers. They're the international gold standards for preventing lock snapping, but barely anyone here knows they exist.
• Proper cylinder sizing and fitting: Gets ignored all the time. Loads of euro cylinders stick out too far from door handles, making them easy targets for snapping.

The bottom line is there's a massive gap between what Australians are doing and what they should be doing. The general security measures like screens and cameras definitely help, but the best protection against lock snapping needs specific knowledge and action that most people just aren't aware of yet.

‍

Which locks are most vulnerable to snapping in Australia?

Euro cylinder locks are absolutely the main target for lock snapping in Australia. You'll find these on pretty much every uPVC door, heaps of composite doors, and some modern timber doors that have multi-point locking systems. The ones that are really asking for trouble are:

• Single cylinder euro locks: Only let you use a key from one side and are sitting ducks. These are common on back doors and some front doors where you don't need a thumb turn on the inside.
• Basic double cylinder euro locks: Haven't been tested to modern security standards and are the worst offenders. Most euro cylinders installed before 2011 fall into this category and have zero anti-snap protection.
• Non-tested euro cylinder variants: Don't have any British Standard markings or security ratings and are basically gift wrapped for criminals. These basic cylinders don't have any sacrificial break points, so they'll snap right at the weakest spot in the middle.
• Thumb-turn euro cylinders: Can be just as vulnerable if they're older models without anti-snap features. Even though the thumb-turn side seems safer, criminals just target the key side anyway.

Here's exactly what makes these locks so easy to snap:

• No anti-snap lines: The cylinder breaks right in the centre instead of at a predetermined safe spot, which exposes the cam mechanism that actually operates the lock.
• Standard grade materials: Basic euro cylinders just aren't built to handle the leverage forces criminals use during snapping attacks.
• Cheap manufacturing: Budget euro cylinders often have metal thickness that's all over the place with weak spots that criminals can easily exploit.
• Wrong sizing and dodgy installation: Makes even decent cylinders more vulnerable. If your cylinder sticks out more than 3mm from the door handle or lock face, it's much easier to grab and snap.
• Older multi-point locking systems: Depend entirely on the euro cylinder and become completely useless once the cylinder gets snapped, even though they've got multiple locking points all around the door.

Here's the thing that catches people out completely: it's not about how much you paid or what brand it is. Even expensive euro cylinders can be vulnerable if they weren't specifically designed and tested to resist snapping attacks. The vulnerability comes down to whether the cylinder was actually engineered with anti-snap features and properly tested to current security standards.

Modern anti-snap cylinders fix these problems with sacrificial break lines, reinforced construction, and proper security ratings like SS312 Diamond or TS007 3-star certification. But these upgraded cylinders are still pretty rare in Australian homes, which is part of the problem.

‍

How do locksmiths can help prevent lock snapping?

Professional locksmiths are your best defence against lock snapping because they actually understand what makes locks vulnerable and know how to fix these problems properly. It's not something you want to mess around with yourself.

When a qualified locksmith comes to your place, they'll have a proper look at all your doors and work out which locks are sitting ducks for snapping attacks. They'll check your euro cylinders, measure how far they stick out, and see whether they meet current security standards. They won't just look at your front door either – they'll check back doors and any side entrances too.

If your locks are vulnerable, they can swap them out for high-security anti-snap cylinders that meet those SS312 Diamond or TS007 3-star standards we mentioned earlier. The important bit is they'll make sure the new cylinders are properly sized so they don't stick out more than 3mm from your door handles.

One of the biggest problems out there is dodgy installation. You'd be surprised how many euro cylinders are fitted wrong, even by builders or handymen who should know better. Professional locksmiths measure your doors properly and install cylinders that sit flush with your door hardware, making them much harder to attack.

If you've got doors with multi-point locks, locksmiths can upgrade the whole system to make sure everything works together securely. They'll also check that your handles and door furniture give adequate protection for the cylinder. It's all about the complete picture, not just the lock itself.

They can also suggest other security measures that work alongside your lock upgrades. Things like reinforced strike plates, security handles, and door viewers that complement your new locks. Professional locksmiths can provide ongoing maintenance too, making sure your locks keep working properly and stay secure over time. They'll keep you in the loop about new security threats and available upgrades.

Many locksmiths understand insurance requirements as well, so they can make sure your lock upgrades meet whatever standards your home insurance policy requires. And if you've been targeted by lock snapping or someone's tried to snap your locks, they can provide emergency replacement and boarding services to secure your property straight away.

The big advantage of using professional locksmiths is their expertise in current security standards and proper installation techniques. DIY lock replacement often leads to incorrectly fitted cylinders that stay vulnerable, even if you've bought the right type of lock.
