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.
You will need an OBD lock kit, a screwdriver, and possibly a socket set, depending on your vehicle model. Follow this step-by-step guide to ensure a successful installation:
- Turn your vehicle off and remove any keys
- Locate the OBD port in your car, usually found under the dashboard near the driver's seat
- Gently remove any panels or coverings over the OBD port
- Secure the lock in place over the OBD port, following the instructions provided with your OBD lock kit
- Reattach any panels or coverings you removed earlier.
You can test the installation by attempting to connect to the OBD port with a diagnostic tool. The lock should prevent access, confirming that your installation was successful.
In addition to installing OBD port locks, RACV recommends the following precautions:
- Secure your keys: Always keep your vehicle keys in a safe place, away from doors and windows, to prevent relay attacks. Ensure you also keep your valuables out of sight.
- Install physical deterrents: Use steering wheel locks or wheel clamps as visible deterrents to potential thieves.
- Stay informed: Regularly update your vehicle's software with a registered mechanic and be aware of any manufacturer recalls or security updates.
"By staying vigilant and implementing these security measures, vehicle owners can significantly reduce the risk of theft," Mr. Ames concluded.
