If you are simply using SwitchArmyKnife to update the firmware on a third-party controller (e.g., making a generic Bluetooth gamepad work on your Switch), you do not need to provide prod.keys. The app functions independently by flashing pre-compiled firmware binary files to the controller.
For Advanced Use (File Management/Dumping): Yes. If you are using SAK in conjunction with other homebrew tools to manage SD card content or if you are using specific builds that interact with system nand backups, valid keys are required to decrypt the data.
A switch army knife key is a compact, versatile tool designed for modern carry needs.
