Crucial note: A "new" prod.keys file is required every time Nintendo releases a firmware update (e.g., from 18.0.0 to 19.0.0). Each firmware version introduces new key generations. If an emulator game requires firmware 19.0.0 keys but you are using keys from firmware 16.0.0, the game will not launch. When you search for "switch prod keys new"

header_key = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
key_area_key_application_00 = XXXXXXXXXXXXXXXXX...

When The Legend of Zelda: Tears of the Kingdom launched, many users with old prod keys from firmware 15.0.0 could not run the game. Even after dumping the game cartridge correctly, their emulator reported:
Missing key: header_kek_source_17
Missing key: key_area_key_application_17
The solution? Obtaining a new set of prod keys that included generation 17 keys. This is why you must keep your prod.keys file synchronized with the latest Switch firmware—even if you do not own that firmware version.
