You might have seen the recent news coverage of CCTV footage capturing the ‘transmitter relay’ theft of a car with alarming ease. And if you're the owner of a keyless entry car, you might be worried. But fear not, vehicle security experts Thatcham Research, are offering guidance to worried drivers. This guidance aims to help them overcome the vulnerabilities presented with these systems. So if that sounds like you, keep reading!

Keyless fobs, (which should not be confused with standard remote fobs) allow drivers to open and start their vehicle without pressing the fob. You don't even have to remove it from your pocket.

Richard Billyeald, Chief Technical Officer at Thatcham Research says:

“Keyless entry systems on cars offer convenience to drivers, but can in some situations be exploited by criminals.”

There are many steps you can take to prevent your keyless entry car from being hacked, read through some of the prevention tips below.

- You’re advised to contact your car dealer. Ask if there have been any updates to the digital software used in your car. Keeping it updated can ensure you've got the best possible software version for your car.

- Check and see if your entry fob can be turned off. If it can be turned off, turn this off each night when you’ve finished using your vehicle. If you’re not sure whether you can turn it off, contact your car dealer to find out.

- Stay vigilant. If you notice anything usual in your neighbourhood, report it to the police.

- Keep your fob away from all doors and windows, anywhere it can be seen or easily located.

Billyeald continues. “We are working closely with the Police and vehicle manufacturers to address this vulnerability. Continuing our approach that has driven vehicle crime down 80% from its peak in 1992.”
