Many of us have enjoyed the ease of keyless entry and start systems in our cars. No more fumbling for keys in the rain, just a tap or a wave and you’re on your way. But what does this convenience come at a hidden cost? 

Many drivers are facing a rude awakening at renewal time: skyrocketing car insurance premiums. One factor behind this surge? A disturbing rise in car thefts linked to a vulnerability – the very keyless technology designed to make our lives easier.

The Hack: How Easy is it to Steal a Keyless Car?

Unlike traditional car thefts, these don’t involve smashed windows or hotwiring. Keyless entry systems rely on a radio signal between your key fob and the car. Thieves can exploit this with a device called a relay amplifier, essentially acting as a signal booster. These devices can be alarmingly easy and cheap to obtain.  The relay amplifier amplifies the fob’s signal from outside your home, tricking the car parked outside into thinking the key is present. This allows them to enter and steal the car in under 60 seconds.

While some key fobs utilise rolling codes, a security feature that changes the transmitted code with each use, effectively preventing replay attacks, the system itself remains vulnerable to relay attacks.

Studies show a significant increase in keyless car thefts and this trend continues globally. The ease and speed of these thefts make them highly attractive to criminals, leading insurance companies to deem keyless-equipped vehicles as higher risk. The result? Higher insurance premiums.

Is Faster Innovation Outpacing Security?

This situation begs the question: are car manufacturers prioritising features over robust cyber security? Should features like keyless entry be rolled out before thorough testing and security measures are in place?
Land Rover, the manufacturer of Range Rovers, has been a recent target of criticism regarding keyless security vulnerabilities. In the UK, Range Rovers became a prime target for thefts due to weaknesses in their keyless entry systems, leading to a surge in stolen vehicles and a significant rise in insurance premiums. This case highlights the need for car manufacturers to prioritise cyber security alongside technological advancements.

So, What Can Be Done?

The good news is there are steps we can take, both as consumers and as an industry. Here are some potential solutions:
For Manufacturers: Implement stronger encryption protocols in key fobs and car systems. Invest in ongoing cyber security research to stay ahead of evolving threats.
For Consumers:

1. Signal Blocking Pouches: Invest in a Faraday pouch that blocks the key fob’s signal when not in use, preventing unauthorised access from a distance.
2. Steering Wheel Locks: While not foolproof, they act as a visible deterrent and can slow down thieves.
3. Be Mindful of Parking: Park in well-lit areas with CCTV whenever possible.
4. Talk to Your Insurance Provider: Some insurers offer discounts for cars with additional security features.
