Drivers are failing to protect their keys, leaving their cars open to relay theft.

Relay theft has been on the rise for some time, yet drivers are still unaware of the risks

Keys for a keyless entry car constantly emit a signal searching for the car in order to unlock it. This can then be explored by thieves who use a signal amplifier and a transmitter that essentially becomes a ghost key and tricks the car into thinking the real key is nearby.

However, half of drivers (51%) do not protect their keys in any way leaving them exposed to so-called relay theft, according to AA Insurance Services.

The problem is on the rise too, due to the speed and ease of stealing vehicles this way as well as the higher cost of used cars and a lack of available parts that makes vehicle theft more lucrative. Figures from the Office for National Statistics show theft of a vehicle rose by 22% in financial year 2021/22 compared to 2020/21.

Of those who do protect their keys, the AA research found most (22%) use a faraday pouch – a small leather pocket with a wire mesh lining which blocks the signal being transmitted. At home some drivers use metal boxes (9%) and safe boxes (7%) to protect their cars, while some wrap their car key in foil or store them in the microwave (both 1%).

Gus Park, managing director of AA Insurance Services, said: “Car thieves have gone high-tech and relay theft has been on the rise for some time, yet drivers are still unaware of the risks surrounding keyless entry cars. Keyless entry is becoming more common too with more manufacturers offering the tech on lower specification cars.

“Drivers should do all they can to protect their keys. While a minority store their keys in the microwave it is not recommended and there are simpler ways of safeguarding your vehicle.

“For as little as a tenner, people can reduce the risk of theft by keeping their keys in a faraday pouch. Depending on the spare key, drivers may need two as this may also be a keyless entry key. They should also be stored well away from the front door and kept out of sight.”
