You can see the different encoding mechanisms the 2 different keyfobs use. In this tutorial, he records the signals and inspects them using baudline. If you’re familiar with the cheap RTL-SDR, then just know the HackRF is like that but more powerful (and can transmit).ĭragorn starts out with part 1: inspecting a pair of car keyfobs. Just like decoding weather satellite signals, decoding wireless remotes and other signals is cool too. Decoding RF signals like keyfobs with HackRF SDR Don't worry, your keyfob has a secondary security for rolling keysĭragorn has a couple of tutorials up on his site about working with the HackRF SDR.
