This is an EM4100, not a T5577. It is not rewritable.

These fobs seem to be built stronger than the other 'blue' fobs. I was excited to start using these. However, they will not program/write. I was cloning another T5577 chip fob at 125mhz. The 'cheap' fobs have zero issues.

These fobs kinda-sorta work, but you can do a lot better.The LF (125kHz) chip claims to be a T5577, but it does not seem to be fully implemented. It comes programmed as an EM410, and works well enough emulating that. However, if you try coding it as HID Prox it doesn't work at all, and some of the other chips supported by the T5577 kind of work but drop bits, show CRC errors, etc.The HF chip works better -- it's a "ZUID" type chip, it honors a small subset of the GDM command set. You can enable Gen2 magic mode if you want, and use the Android MCT app to write it -- but you'll need a Proxmark to do the enabling anyway. It comes configured as a Gen1a chip, which uses the "Chinese magic" commands. Proxmarks, Flippers and a variety of Chinese cloners can set the UID in this mode. You cannot, however, disable the Gen1a mode, and some readers will detect the chip's response to the "magic wakeup" command and reject it as counterfeit. You can also change the SAK, but there are no hidden pages, no shadow mode or any of the usual GDM goodies.Also, the range is pretty bad, the HF chip needs to be right on top of my Proxmark or Flipper to read. The LF chip will work at a range of an inch or so. Neither of those is great.If you REALLY want two credentials on your keychain right now, and one of them is an EM410x and the other is a MF Classic without a very picky reader, you could try this -- but you can find better dual-chip cards and fobs around.
