Does OBD hacking compromise your van security?

Did you know that thieves can steal one of your vans within 90 seconds using nothing more complex than a standard laptop or handheld PDA (Personal Digital Assistant)?

It’s shocking, but true. All the criminals have to do is gain access to your vehicle using a key jammer, an easily available lock pick or simply by finding the doors have been left open (see our post on How to protect your business from van theft for more details of these techniques).

Once inside, the thieves simply have to plug their laptop or PDA into your van’s OBD (On-Board Diagnostic) socket. Engineers normally use this port to gain access to your van’s computer systems, allowing them to check diagnostic data and troubleshoot technical problems.

Criminals do something different. They override your van’s immobilisation system and programme a new key into the ECU (Engine Control Unit). Experienced thieves can do this in moments, driving off to leave you facing the expense, inconvenience and hassle of a stolen van.

But are you at risk?

Vehicles at risk of OBD hacking

If you own a Ford Transit, Ford Connect, Ford Fiesta van or a Mercedes Sprinter LCV, then the answer is almost certainly yes. Some other models are vulnerable too, so we advise you to get in touch so we can advise you whether you need to act.

(It's also worth looking at the cars in your fleet, and your personal vehicles. Some models like BMW are particularly at risk from OBD hackers).

Luckily, there is a way of stopping the thieves in their tracks — by fitting an OBD protection device.

These devices encase your OBD connector in a secure box, which is usually fitted to the anti-roll bar behind the dashboard of your vehicle. It can only be unlocked using the correct code or key.

Security accreditation for OBD protection devices

While effective, you need to be sure that any aftermarket OBD protector meets a high standard of security. Look for devices that have been tested by Sold Secure or the Thatcham Motor Insurance Repair Research Centre. Every item accredited by these organisations has been extensively security tested by professionals, virtually guaranteeing that they will foil even the most determined van thieves.

While it certainly costs money to protect your fleet against OBD hacking (and also to install other features like unpickable locks), it’s a small price to pay compared to the cost and inconvenience of seeing your vehicles stolen to order, or driven away by opportunistic thieves.

But if the cost of protecting your fleet starts to look daunting, it may be worth thinking about hiring your vans. If you do, you can order them specially fitted with all the latest security devices — for a minimal, extra monthly cost that allows you to spread your budget further and prevent unnecessary capital outlay.
