Hmmm. I'm thinking if/when I get my Tesla Model 3, I'll get a "dummy" RFID card/fob. One that will NOT activate the car or any of its devices. Maybe an old ID card from an employer from long ago (or perhaps I'll just get an RFID card that reads 0000 0000 0000.)
I'll place this dummy card somewhere at home, like taping it to the inside of my garage/kitchen door -- anywhere so its closer than my actual card. If any less-than-savory people come snooping by with an RFID repeater, it will pick up the closest card (the dummy), and repeating that card's signal it won't do anything to unlock the car.
