They use the tech that Canada is trying to ban to intercept that signal and another piece of tech to basically repeat it so the vehicle thinks the thieves have the key
Although if the signal is vulnerable to a replay attack just like that, it was a woefully poor design to begin with.
It’s why a lot of garage door systems don’t use a fixed code, but something more like 2FA codes, where it changes each time it’s used.
You’ll get no disagreement from me. I feel the same way about RFID ID tags. I remember seeing a CSI episode once where girls were getting RFID chips implanted in their wrists or something and using that to pay door fees and tabs at bars. I would never. I can and have cloned an RFID badge (to avoid paying $80 to my apartment complex for a badge that was inaccessible because it fell into a crevice of a locker at a gym), and I gotta tell ya, it doesn’t take enough time for me to be comfortable using it as a security feature for most anything.
