It may have been as simple as getting gas. I don’t take my kids out getting gas, that would also be a stupid decision to expose them to moving traffic and unknown predators whole I’m occupied operating the pump. I do take my keys out of the car, and lock it, but my wife’s key fob will start the car with me standing at the passenger side door. We know because we’ve tested this when we heard these types of thefts were happening around us. So when I get gas, I rig the pump to stay on with my gas cap and stand back. Even then people carry repeaters now that boost the signal of your key…super low tech and cheap to be had…considering getting an RFID pouch for just this purpose; steal the car but just leave the kids.
