The [WARN] prod.keys does not exist message is one of the most misunderstood and feared outputs in the Switch modding toolkit. But as we've seen, for the vast majority of users, it is a harmless notification, not a fatal error. It's a bit of nagging from a tool that's thorough in its checks, even when those checks aren't required for the task at hand.
The keys are derived from your Switch console's unique hardware (specifically, the TSEC and keyblobs) and are not something that can be shared legally or generated without access to a physical console. If you need the prod.keys file for your legitimate projects, you must generate it yourself using tools like Lockpick_RCM , which is the standard method for dumping keys directly from a hacked Switch. hactool --keyset=/home/username/Downloads/keys/prod
If you'd prefer to avoid typing the -k flag for every command (which can be tedious), you can solve the problem at its root by placing your prod.keys file in the folder hactool expects it to be.
If the above steps don't resolve the issue, it's time to dig deeper: The [WARN] prod
To obtain your prod.keys legally, you must dump them from your own hacked Nintendo Switch console: Boot your Switch into RCM mode. Launch the payload. Select the option to Dump from SysNAND .
If you haven't dumped your keys yet, you'll need to do that from your own console (legal/CFW methods only).
