One thing I'd love to do with this, but which I don't think is possible - clone my car key. My family has two cars and I just wish I could have one device that is able to unlock & start both of them so that I don't have to carry two bulky dongles on my keychain.
The Flipper can unlock some cars, and the hardware has support for rolling codes, but as I understand it, the standard firmware deliberately does not enable this functionality to discourage abuse. Several people on the Discord have managed to unlock their cars once or twice, and inadvertently desync their cars from all of their key fobs in the process, leaving them with no devices that can unlock their car.
I think that's for a good reason. I suppose the implement a hardware public-private encryption and they transmit random data everytine you press a button
