I use mine for cloning key fobs when i need work access to a mechanical room after the fob has been returned. Lot of times i need access to a mechanical room or rooftop drains and cant get a copy of a fob. No problem, most of the time. Only run across two i couldnt clone and i think it was operator error.
I also turn off loud tvs with it. And at the machine shop across the way, i like to pop the charging port on the Tesla the owner drives. Im still looking for a gas station with RF signage so i can see if that works.
Flipper is a neat bit of electronics, but its sorta like a swiss army knife - it does lots of things ok but there are better solutions out there.
Proxmark3/4 and a laptop for 125khz and 13mhz cloning and attacks, HACKRF one (any tx capable SDR that can get into khz range) and gnu radio and whatever custom built antenna you need for whatever frequency youre working.
Those things are pretty hit or miss. Fickle, poor quality IR LED, not a very large code base.
The IR database for the Zero is pretty comprehensive. Televisions, stereos, dvd, air conditioners, fans, etc. quite literally everything with a IR LED. It also has the ability to ‘learn’ new remotes that it doesnt have preprogrammed. I have yet to find a TV it cant control.
However, new fobs use rolling codes. Youll likely get it paired, use it once, then when the code rolls, you end up deauthorizing your fob because it is behind on rolling code. Sometimes itll work for a few uses, if you have multiple keyfobs (it has to do with how the vehicle, Fords in particular, handle the way code is used) but YMMV.
Old school keyfobs work, tho. Garage doors are much the same.
Even new garage doors use rolling codes, for exactly this reason. People could break into houses with a flipper and a little patience.
Cloning a fob that has rolling codes, and then using it to unlock the car, may de-auth the real fob and lock the person out of their car until they pay (sometimes $$$) to get it recoded. So, unless you have actual malicious intent it's a pretty shit thing to do.
