The only thing I can think of is having incredibly tight timing on a challenge/response. With ~10 nanosecond level precision, it's not physically possible for em waves to travel more a few meters before the time is up.
How about a simple faraday shield for the key fob?
Might as well have a push button instead. Having it work from your pocket without interaction is what makes a fob different and should be a design requirement.
How about making the signal so weak that you have to put the key inside a hole in the car for it to work?
