But some drivers have had their vehicles stolen despite having their keys locked away in a signal blocking box.

Keri Yates had her £24,000 Range Rover stolen in just 20 seconds outside of her house, despite her keys being locked away in a signal-jamming bag inside her Burntwood house.

“Apparently they’re only good when you go away on holiday, it doesn’t work if you keep putting your keys back in and out.”

A Thatcham Research spokesman previously told AutoExpress: “We have tested a few of the pouches and the ones we’ve assessed have worked, but we can’t guarantee they all will.
