Technology-savvy thieves in Victoria are targeting some of the most popular makes of cars and fuelling a surge in vehicle crime, police warn.

Cases of cars are being stolen from residential streets, driveways, and other community locations, where no burglary, robbery, or carjacking takes place are increasing.

While there are instances where people leave their keys in their car, most commonly in these thefts, the owner reported to police they kept the keys and their car had simply vanished.

Officers say as many as one in five Victorian cars are stolen in these circumstances as thieves turn to the emerging technology.

Car thefts using third-party electronic devices have been occurring in other countries such as the US and Britain for several years and are now becoming more common in Australia, police say.

The trend has coincided with third-party electronic devices, capable of programming or mimicking keys, becoming increasingly available for purchase.

Once inside a vehicle, this device can be plugged into its diagnostic port on the dashboard to override the security system and start the engine.

Some of the most popular makes and models of car are being targeted with this technology by thieves in Victoria, police say.

Cases of Holden Commodores being stolen increased by 92 per cent, up 1377 in the 12 months to January 2025, when compared with the previous year.

During the same period, thefts of Toyota vehicles, such as the Landcruiser, Prado and Rav4, were up by 1391, (76 per cent), while there was a 107.8 per cent jump – equivalent to 402 cases – of Subaru vehicles, including the Impreza/WRX and Outback, being taken.

The increase of key programming devices for sale has led to levels of car theft not seen in Victoria since 2003.

In the 12 months to September 2024, 25,773 vehicles were stolen in the state – 6408 more than the previous year.

Victorian Police have arrested numerous offenders for stealing cars using these devices, but are warning vehicle owners to be vigilant.

“We strongly encourage owners of impacted cars to consider all possible methods to improve their vehicle’s security – there are a range of auto shops and websites that stock these anti-theft products, and staff can assist with advising you on what will best suit your vehicle,” said Detective Inspector Julie MacDonald.

“Vehicle owners can also speak with manufacturers or their insurance agents for further advice.”
