Can you monitor the frequency 433.215MHz via GnuRadio a standard RTL SDR DVB USB device?

  Maybe it's similar to the TPMS (tire pressure monitoring system) as talked about here: https://news.ycombinator.com/item?id=30619612 https://news.ycombinator.com/item?id=30619612

  Yes. You can even listen to the warble of the codes. And those of my, well your, neighbors. I did my own research (albeit not as far as this person) a couple years back and the 2018 CR-V is also vulnerable.

  What you're looking for is RTL433[0]. [0]: https://github.com/merbanan/rtl_433 https://github.com/merbanan/rtl_433

  Yes you should be able to, or with slightly more friendly software like gQRX or SDRSharp. It also looks like you can receive and decode the key signals using rtl_433[0] with option -R 64. Although it's a bit confusing looking at the source for the honda key rtl_433 decoder, as the author states it does not decrypt the rolling code.[1] According to the CVE there is no rolling code.
