I have a HackRF One, can do the same type of stuff with it. Lots of fun. There's a lot of information flying around the air too that is ostensibly pretty benign, but could be messed with too. Electric smart meters, tire pressure sensors, smart home devices, baby monitors, cameras, you name it.
I remember it, seem to remember it didn't work very well either.Anybody remember the ‘80s GM vehicles with the key cylinder on the front fender? Used the same key as the door locks and it was GMs answer vehicle security. I mostly remember them on the Caddys, particularly the Eldorado & Seville. My Toronado had one, but it was next to the filler neck behind the rear license plate
