5/5 – Reliable, Easy-to-Use, and a Great Value
I've been really impressed with these T5577 rewritable RFID fobs. I picked up the 10-pack to use with a handheld RFID writer, and every single tag has worked flawlessly so far.I’ve used them in a few real-world scenarios:Made a backup fob to keep hidden in my truck just in case I lock myself out or misplace the original.Cloned a pet-sitter fob while I was on vacation so they could access my building without needing to hand over my main one.Copied a pool access fob for my friend group, so we can all get in without having to juggle the original back and forth.Cloning and rewriting have both worked without issue. I've tested re-writability multiple times on the same fob, and it’s held up perfectly each time—no failures, no weird behavior. The chips respond consistently, and I haven’t had a single dud in the pack.Heads-up for first-time users:These come blank, so you must have a compatible 125kHz RFID writer to program them. They won’t scan or read until they’re written to. That’s not a flaw—it’s just how the T5577 chip works. Also, don’t expect these to work with systems like Onity or Proxmark3 RDV4; they’re great for common 125kHz formats like EM4100 and HID.The fobs themselves are durable with a solid keyring hole, and the black color looks clean and low-profile. At under a dollar per fob, this is one of the best values I’ve found for RFID work.Highly recommended for DIY security backups, access sharing, and general RFID cloning projects.

Worked for our condo
Needed additional fobs for our condo and didn't want to spend $50/ea for two more. My son's friend had a copier and it worked perfectly.

Work perfectly. Easily written with Flipper
Work exactly as described. Needed a few extra building fobs so I bought these. I was able to read my key with the flipper and then write to these immediately without issue. These operate at 125kHz, so make sure that is the protocol your device uses or it will not work.
