To use amiibo data (often found as files), you need specific encryption keys to "unlock" the data so apps or devices can read and write them. 1. Identify the Required Key Files The two standard files you will need are: locked-secret.bin (sometimes called unfixed-info.bin unfixed-info.bin (sometimes called locked-secret.bin Many apps now look for a single combined file often named key_retail.bin 2. Where to Get Them
"Power Tags" are rewritable NFC cards/stickers. Users buy a device like the N2 Elite or Puck.js. They dump 200 amiibo onto one device. The device’s software requires the key file to emulate the decryption process on-the-fly. amiibo key files

Amiibo figures use NFC (Near Field Communication) technology, specifically NTAG215 chips. These chips are encrypted by Nintendo to prevent unauthorized duplication. Where to Get Them Group 2: The Power
| Filename | Role |
|----------|------|
| key_retail.bin | Main encryption key for amiibo data |
| key_retail_2.bin | Alternate/secondary retail key |
| key_common.bin | Common key used in crypto operations |
| unfixed-info.bin | Contains initial dynamic data needed to emulate unique amiibo behavior |
| locked-secret.bin | Used in some homebrew tools for full tag emulation |
⚠️ Never share these files. Each amiibo’s UID is unique, but sharing the encrypted payload violates copyright and can expose you to legal risk.
Legitimate use cases for key files (if obtained from your own legally purchased hardware) include:
