RACV is alerting Victorians to a rising trend in car thefts using on-board diagnostics (OBD) ports.
Thieves are increasingly using electronic devices to access vehicles via their OBD ports, enabling them to start and steal cars without the owner's key. Victoria Police data has shown that 20 per cent of car thefts in 2024 were stolen using this method.
RACV General Manager Motoring Products Jeff Ames explained how offenders were targeting modern vehicles.
"By connecting unauthorised devices to a vehicle's OBD port, a thief can communicate directly with the car's engine control unit, allowing them to program a new key or even start the engine without the original key," Mr. Ames said.
In addition to OBD port-related theft, RACV is also warning motorists of 'relay theft' – where thieves use a device to amplify a signal from your car key, tricking a car to unlock and even start.
"As vehicle technology advances, so do the methods employed by criminals, so it's crucial for motorists to be aware of these tactics and take appropriate steps to protect their vehicles."
RACV recommends the installation of OBD port locks to prevent push-start car theft. An OBD lock works by physically securing the OBD port, preventing unauthorised access.
"An OBD lock is a simple, yet effective tool that can significantly reduce the risk of theft by blocking access to the port," Mr. Ames added.
How to install an OBD lock
In general, OBD port locks are easy to install yourself. OBD port locks are cheap and readily available from auto shops and vehicle anti-theft websites.
