It would be amazing if one could use the Flipper as a backup car key, not to mention a huge money saver compared to buying another key from the dealership.
Potentially multiple frequencies. Unclear if there is a use case for push to start literally pressing on the ignition vs. the other key functions (former works with no battery in FOB).
Info on RF modulation and if it’s possible to store multiple “keys” to use the Flipper as a backup key - broadly I think that captures it and would be a HUGE money saver
I’m not sure on the last one, but the only other category calling out other frequencies didn’t look best suited at a glance.
There’s a complication of “Rolling Codes” used by car keys that I don’t fully understand how difficult it would be to emulate a key using a Flipper. Unclear if you could brute force it to work or if a single incorrect “reply” starts the entire process over again.
