Cool. An xM1 (NExT, xMagic, flexM1, or flexUG4) should do the trick. If it’s not reading, it’s a coupling issue. Try working around the hf field detector keychain and see if you can get it to light. It looks like it’s got some locked keys. I believe the there’s an app for the Flipper to help with those (I haven’t used it). A Proxmark would probably be better. But, I’d be curious if you could get enroll your NExT rather than try to clone the ring to it. If you can’t get the field detector to light, it would be worth getting an rsp or mfgc so see if you can improve things enough to get a read.
Edit: NExT is incorrect here. My bad. So tired today
