A Landcruiser holiday turned catastrophic for one Australian family when thieves used a device available on Amazon to clone their car keys and drive away with their vehicle, their savings, and their peace of mind. The Kent family discovered their car missing from their driveway; it was later found stripped and burnt. Their experience reflects a rapidly escalating national problem: organised car theft rings are using legal, readily available technology to overcome keyless entry systems faster than manufacturers can patch them.
The technique exploits a fundamental weakness in modern car design. When an electronic fob is inside a house but still within range of the car, the device can intercept the wireless connection and mimic the car key's signal to unlock the vehicle. Once unlocked, the vehicle starts without the physical key present. Remarkably, it was considered impossible to steal a car this way as little as two years ago, according to Victoria Police.
The scale of the crisis
This is no longer a niche criminal technique. Police intelligence estimates as many as 30 cars are being stolen using key cloning technology in Victoria every day. Victoria police say their intelligence suggests one in five stolen cars in the state have been taken using a key reprogramming device.
The financial impact reverberates through the insurance system. In the 12 months to June 2025, Victoria saw a 59 per cent jump in claims and a 70 per cent spike in costs, totalling $223 million. This cost burden filters directly to consumers through higher premiums, hitting families already stretched by cost of living pressures.
Certain vehicle models face disproportionate targeting. Holden thefts increased by 92.9% in the 12 months to January 2025, whilst Toyota thefts increased by 76.4%, with Hiluxes, Landcruisers, Camrys, Prados, Rav4s, 86s and C-HRs manufactured within specific year ranges all being targeted. The common thread: these vehicles use push-button start systems vulnerable to signal cloning.
A governance failure
The fundamental problem is that these cloning devices are perfectly legal. Thieves can purchase them from mainstream retailers, often for as little as 20 dollars. Victoria Police seized more than 800 such devices from individuals arrested for car theft in the past year. The devices have legitimate security research purposes, but their widespread availability, combined with their relative invisibility in home security conversations, means most car owners remain unaware of the threat.
This represents a clear market failure. Manufacturers recognised keyless entry as a convenience and security feature; thieves now exploit it as a vulnerability. A cybercrime expert at UNSW advises people to "be alert, but not alarmed," noting that many people dump their keys in a bowl at the front door, which is where they come unstuck. Yet few households take precautions, partly because the threat seemed theoretical until recently.
Defence measures exist, but require action
Protection is achievable, though it demands deliberate effort. Storing your keys in a Faraday box, bag or similar RFID blocking device can help prevent thieves from copying your key fob. Wrapping keys in aluminium foil offers a crude but effective barrier. More visible deterrents such as steering wheel locks add friction; even if a car can be cloned and started, physical barriers slow thieves and increase the risk of detection.
Some jurisdictions are moving beyond individual responsibility. Queensland state government invested $10 million into an Engine Immobiliser Subsidy Trial, providing up to 20,000 engine immobilisers for residents, and the Queensland Police Service advises that there have been no reports of a vehicle fitted with an immobiliser being stolen. This reflects a pragmatic recognition that expecting every householder to understand signal-blocking technology is unrealistic.
Where accountability lies
The unsettling gap in this story is vehicle manufacturer responsibility. Car makers have known for years that keyless entry systems carry vulnerabilities. Yet the financial incentive to address them through hardware recalls or software updates remains weak, since insurance companies typically cover theft losses. There is little direct commercial pressure on manufacturers when the cost of theft is socialised across the insurance pool and then distributed back to consumers.
This creates a perverse alignment: manufacturers profit from convenient technology; consumers bear the risk; insurance companies absorb the initial cost; then households pay again through higher premiums. Meanwhile, police spend resources pursuing thieves equipped with tools that remain legal to own and distribute.
For the Kent family and thousands of other Australian drivers, the crisis is no longer theoretical. The immediate path forward requires household awareness and basic protective steps. Longer term, it demands a reckoning: either manufacturers engineer and implement meaningful security fixes, governments regulate the distribution of signal-cloning devices, or insurance structures change to create genuine incentive for prevention rather than merely compensating loss.
In the meantime, Australian families can protect themselves by storing car keys away from doors and windows, investing in RFID-blocking Faraday pouches, or installing engine immobilisers. As thieves grow more sophisticated, consumer vigilance and government action must keep pace.
