I've just bought myself a new car which has a keyless entry system. I love it. It's very convenient. However it seems that the criminal fraternity can easily overcome this. Car theft is not really an issue where I live but I do travel a lot so I've been looking into the Faraday pouches that apparently block any signal from the key fob. That's all very well but it completely negates the convenience of the keyless entry when you have to remove the fob from the pouch to open and start the car. Is it one or the other? First world problem, I know. Also it seems that the pouches have a life expectancy. Why would this be? Any thoughts.
