If you decide to hunt down these files, do so ethically: dump your own keys if you have a modded console, or verify checksums before loading community-shared files. Use them to back up your collection, not to produce counterfeit toys for profit.
However, with great power comes great responsibility.
Verify your key files are the correct size. unfixed-info.bin is usually 175 bytes, while locked-secret.bin is 81 bytes. Ensure the target tag is a true NTAG215 chip.
The legality of possessing amiibo key files hinges on the in the US and similar laws globally. amiibo key files

Amiibo key files contain the cryptographic data needed to unlock the encrypted sections of an amiibo chip. Without these keys, backup software cannot interpret the data structure of a dumped amiibo file ( .bin ).
I can provide direct links to reputable, open-source . If you decide to hunt down these files,
The legal status of amiibo key files falls into a gray area of intellectual property law. The keys themselves are proprietary cryptographic algorithms owned by Nintendo. Distributing or downloading these files directly violates copyright laws in many jurisdictions. Consequently, major emulation projects and app stores strictly prohibit hosting or linking to these files.
Dump your amiibo (backup the physical)

Hardware like the Flask or JoyCon Droid (Android) allows you to store hundreds of amiibo bin files on a phone or a dongle. To use these virtual tags, the emulation software must re-encrypt the raw data on the fly. Without the key file, the Switch will see a fake tag and reject it. With the key file, the software can produce a valid cryptographic handshake.
Key files are also necessary for players who prefer to use physical backups instead of emulators. Devices like the Amiibo Link, Pixl, or custom-programmed NTAG215 cards require key files during the creation process.
: Legitimate tools and open-source platforms (like GitHub) will never bundle the key files with their software. Users must supply their own files. Enthusiasts typically extract these keys directly from their own hardware using homebrew-enabled consoles.
Once a user possesses the necessary key files, a wide variety of hardware and software tools become functional. 1. Creating Custom NFC Tags (NTAG215)
