Police have arrested 25 people in the South East this year allegedly linked to using reprogramming devices to steal cars.
Greater Dandenong, Casey and Cardinia Superintendent Mark Langhorn said an “alarming number” of the devices had been uncovered during search warrants or in the possession of thieves.
“Offenders are evolving their techniques to steal cars, and police are also changing tactics, which is evident in the number of arrests being made.”
The third-party electronic devices are used to steal cars in minutes without the need for car keys.
Once inside the vehicle, the device can be plugged into the car’s on-board diagnostic port to override the security system and start the engine.
In Victoria, car theft was up more than 40 per cent in the past year, reaching nearly 30,000 vehicles and the highest levels since 2002.
Up to 20 per cent of the thefts involved reprogramming devices, police say.

Police say that certain car makes and models with electronic push buttons are vulnerable to the new technology.
In the 12 months to January 2025, Subaru thefts soared by 107 per cent, Holdens by almost 93 per cent and Toyotas more than 75 per cent.
Models made in the mid-2010s are the most frequent targets, police say.
Supt Langhorn advised owners to take preventative measures to deter thieves, including an onboard diagnostic port lock.
These locks are affordable and self-installable, according to police.
“We encourage car owners to fight fire with fire – without installing technology to block these reprogramming devices, it is likely that we will see even more cars stolen in this way.
“While it’s an added cost, it’s much cheaper than the alternative where you have to replace your vehicle.
“We know thieves go to great lengths to steal a car, so taking an extra step to secure yours could make all the difference.”
Parking off the street and always locking the vehicle are also advised.
