I thought many gym and apartment key fobs can’t be replicated due to rolling keys. Has this been addressed or flipper works on older fobs?

Rolling keys is more of an RF thing, fobs are NFC or RFID (rolling key is still vulnerable to a simple replay attack).

For NFC/RFID it depends entirely on the card. You can easily clone Mifare Classic, but on newer ones there's no way I know of, and the software does not (yet) have support for Legic (which has been broken for over a decade).

I’m in Malaysia. We still think RFID is a new thing
