I was really excited to get mine! It is neat. I got it and it has been in my drawer almost exclusively. I have done exactly two things with mine:
* Opened my friend's Tesla battery charge hatch from a distance for fun (it closes again on its own after maybe 30 seconds)
* Recorded a lamp's IR remote on/off/up/down toggles and used the Flipper to turn on the lamp, rather than using the IR remote, to try to debug whether the remote was going bad or if there was a problem with the lamp (it was the lamp itself)
And I tried, unsuccessfully, to:
* Read my dog's microchip data
Otherwise, I haven't found any use for it. I really wanted to like it. I did a search to see if there was anything interesting to do with it that I was missing, and basically it's what I did (or failed to do) above. Some people also use it to change TV channels at restaurants as a prank it looks like.
- xvector 2y agoSame experience here. I don't blame the Flipper, though, only my own lack of creativity and energy.
- okdood64 2y agoDo you know if I can emulate car keys with it? Say a relatively modern BMW? Or is there some safety mechanism. (Not for nefarious purposes, but just in case I can’t find my keys.)
- Rebelgecko 2y agoIIRC it's somewhat possible but for some cars if you do it wrong it makes the car and key go out of sync which causes a lot of issues
- dumah 2y agoEmulating the rolling code protocol would desync your keys. What ever device you’d want to use as a backup would need to capture information sent from the vehicle during the last unlock.
- obituary_latte 2y agoNot natively. There is other firmware out there, though, that allows such functionality. Depending on where you live, it may be illegal to even try, though, hence the native firmware locking out such use (you can record or visualize but not save/replay).
- echoangle 2y agoJust recording and replaying wouldn’t help you anyways, the code is rolling to prevent replay attacks.
- virtue3 2y agoI think if you have enough replays you can deconstruct the rolling code. Not sure. Also there are ways to desync/resync your key so you might be able to “add a key” with the flipper with certain firmwares. Cloning the current key and using it can desync it from your car. Super annoying. Be careful
- echoangle 2y agoI don’t know exactly how the rolling key works but wouldn’t it be kind of like having a secret stored in the key that’s needed to generate the next code? If it’s designed properly, recording a few thousand codes shouldn’t tell you anything about the next code, just like you can’t deduce private keys by looking at a few thousand encrypted files. I have no clue if that’s really how it works, so I would be happy to be corrected if my mental model is wrong here.
- bongodongobob 2y agoBasically yeah. You'd need millions of replays to even have a chance. Cracking basic wifi back in the day required a couple days worth of sniffed packets. I'd imagine this is similar, if there is in fact a way to do it.

- fullstop 2y agoDon't do it. The key can easily get messed up if the rolling code isn't handled appropriately.
- kevin_thibedeau 2y agoThe old Ford transponder keys don't do rolling codes.
- askvictor 2y agoSo an attacker can cause your car keys not to work?
- fullstop 2y agoYes, as well as gain access to your vehicle. This has been reported on quite a bit over the last couple of years.
- aftbit 2y agoSo far I have not been able to emulate the keys on either of my cars, a 2001 Ford Ranger and a 2019 Subaru Outback. I think the Ranger is probably possible, but I haven't figured it out yet.
- jrussino 2y agoI'd love to have this, mainly so that I could have a single dongle on my keychain for both my and my wife's car. I know others have said that there are issues around rolling codes. But it's possible to get official duplicate / replacement keys; how does that work?
- fullstop 2y ago1/4th of my cats have microchips. They were moderately annoyed as I scanned them. The whole microchip registry thing is a mess, though. There's no authoritative database and I'm certain that the database entry for my cat is at some shelter where he was briefly held. I have no way of updating this data without paying a subscription fee, so that's out of the question. Outside of IR remotes and popping tesla ports, I have used it to emulate RFID tags. I don't have enough free time to really utilize it appropriately. Cat tax: https://i.imgur.com/8vAabRM.jpeg https://i.imgur.com/8vAabRM.jpeg -- He is sleeping where he really should not be sleeping.

This could be applied to dogs too... but cats rule the internet ( https://en.wikipedia.org/wiki/Cats_and_the_Internet https://en.wikipedia.org/wiki/Cats_and_the_Internet )
- fullstop 2y ago> Here's a ML problem for someone to consider tackling ... given a cat picture, identify all of the relevant cat subs that it might get posted in I'm fairly certain that there are an infinite number of cat subs, so this task is impossible!
- shagie 2y agoWhile "yes" ... there are only so many that are big. Getting the top 100 cat subs and going from there would be a nice ballpark number. Its one of the "this might be a fun thing to do if you're playing with a ML image classification problem." I've got a Mac and so https://developer.apple.com/documentation/createml/creating-an-image-classifier-model https://developer.apple.com/documentation/createml/creating-... has tempted me on occasion to see "how much can this thing do?"

- bowmessage 2y agoCan you emulate common TV IR blaster protocols without first recording them? I used to have an LG G4 android phone with a TV remote app built in- with just the TV manufacturer information, I could change the channel / volume in all sorts of useful places (the gym, etc.). I miss this feature often.
- pizza 2y agoFor God knows why reason, the original PSPs used to come with an IR LED. I put a homebrew program on my PSP that let you control it, and fed it a txt file with thousands of TV IR codes. What a blast!
- bigiain 2y agoYep: "Flipper Zero has a built-in library of signals for common TVs, ACs, projectors, and stereo systems brands. This library is regularly updated with new signals, thanks to the Flipper Zero community's active contributions to the IR Remote database." (from the flipper zero homepage) I've successfully used mine as a "TVbGone", switching off all the TVs in a bar...
- bowmessage 2y agoThank you, and sorry for being so blind. I think this is enough to sell me on one!
