Most car thieves aren't going to spend thousands on such equipment just to steal your car. They're better off just pick-pocketing you, or paying off their buddy at the dealership who can get a digital key made for any car based on the VIN number.

I have a new car with one of the fancy key fobs that just needs to be in your pocket or purse to open or start the car. I can’t tell if all the concern from next door about some new technology that can replicate the fob’s signal is real or not. Thoughts?
