I'm reminded of when key fob range extender attacks became common, security people were talking about faraday cages, removing batteries every night, encryption, more complex protocols, and all sorts of crazy stuff to try and protect against it. Car manufactures added a motion sensor to the fobs to disable the signal after being motionless, and that's all that was really needed to kill the attack.
