Preventing Vehicle and Car Part Theft: Practical Security Tips

Vehicle theft is not limited to someone driving the whole car away. Items inside the vehicle, number plates and accessible components can also be targeted. The most useful response is to make the vehicle harder to access, harder to start and less attractive to an opportunistic thief.

Lock the vehicle every time

Victoria Police recommends locking doors and closing all windows even when the vehicle is parked at home or left for a short period. Do not leave a vehicle running unattended. Physically check that it has locked rather than assuming the remote signal worked.

Secure the keys

Modern vehicle theft can involve electronic access as well as stolen physical keys. Keep primary and spare keys in a secure location. For vehicles with keyless entry or push-button start, consider whether a Faraday bag or other suitable key-protection method is appropriate for your vehicle.

Park where the vehicle is visible and secure

A locked garage is preferable where available. If the car is on a driveway, lighting and CCTV can improve visibility. On the street, choose a well-lit position rather than an isolated area where a thief can work unnoticed.

Remove valuables and documents

Do not leave phones, bags, tools, GPS units or other visible valuables in the vehicle. Documents can contain personal information and your home address. House keys and garage remotes should not be left in the car either.

Consider appropriate anti-theft devices

Victoria Police lists measures such as steering-wheel locks, alarms, immobilisers, OBD-port locks and tracking devices among options that can make some vehicles harder to steal. The right device depends on the vehicle and its existing security system.

Protect number plates and accessories

Anti-theft screws can make number plates harder to remove. External toolboxes and removable equipment should be locked or taken out of the vehicle where practical.

Do not confront a thief

If theft is happening, personal safety comes first. Victoria Police advises against confronting offenders. For an emergency or a crime in progress call Triple Zero (000); for non-urgent reporting use the Police Assistance Line or online reporting service.

If the vehicle is no longer worth keeping

Security costs are only one part of owning an older or damaged car. If the vehicle is no longer reliable or worth repairing, compare its current value and disposal options rather than leaving it unused for long periods. Our vehicle value guide can help with that decision.
