In today’s digital world, vehicle security is evolving. It’s no longer just about steering locks or immobilisers, it's about safeguarding both your car and your digital footprint. Here’s how to stay secure in the modern motoring age.
Traditional security still matters
From steering-wheel locks to physical immobilisers, tried-and-tested methods still work. Mechanical devices are visible deterrents and still prevent many smash-and-grab thefts. For vehicles parked in high-risk areas, layering door locks and tracking devices offers added security.
Electronic protection
Increasingly, thieves are targeting vehicles’ electronic systems:
- Keyless entry systems work brilliantly, until your fob’s signal is intercepted. To prevent relay attacks, always store your key in a shielding pouch or a Faraday box, especially overnight.
- Onboard diagnostics (OBD) ports can be hacked to start engines or disable immobilisers. Your local garage will usually secure these, but if you use a mobile mechanic, check they’re covering the port while they work.
Cybersecurity
Modern cars often come with Wi‑Fi connectivity, apps, and infotainment systems:
- Change default passwords on factory-installed systems and avoid linking sensitive personal accounts unless you’ve got good security.
- Keep your car’s software and firmware up to date (some manufacturers issue security patches just like laptop or phone updates).
GPS
Many garages now offer optional GPS tracking packages that tell you if your car moves without authorisation, or if an accident triggers a sudden stop. These systems can assist in recovery and provide peace of mind.
Park smart
- Always lock your vehicle when it’s left unattended, even in your driveway.
- Park in well-lit areas, near CCTV or foot traffic where possible.
- Avoid storing high-value items on display. Even something as small as a phone can increase risk.
Choose a trustworthy garage

Check your insurance
Even with the best defences, it's wise to review your car insurance policy. Ask your garage about market-leading options that offer theft or cyber-based damage cover, especially if your vehicle has advanced electronics or connectivity features.
Limit tech crime
Avoid plugging in unknown USB devices into your car’s infotainment system. Malicious software or phishing via unfamiliar cables can open pathways into your vehicle’s systems. Stick to manufacturer‑approved accessories.
Report your concerns
If you live in a community with repeat vehicle thefts, join or start a neighbourhood watch or car‑club forum to share information about suspicious vehicles or tactics.
Protecting your car today is as much about digital vigilance as it is about physical security. A layered approach, from mechanical locks, encrypted and shielded key tech, to up‑to‑date software, and using trusted garages, is the best defence. Always stick with accredited professionals, secure your electronics and parking, and stay proactive.
