Exist Top: Hactool Prodkeys Does Not

Your query includes the word "top." This usually refers to one of two things:

There is no command called hactool top. If you type hactool top, you will get an error. The correct command structure is hactool --keyset=./prod.keys <file.nca>.

You cannot legally get this file from a public repository. You must dump it from your own Nintendo Switch console using tools like:

⚠️ Do not ask for or share prod.keys online — it contains console-unique cryptographic keys. hactool prodkeys does not exist top

| Mistake | Fix | |---------|-----| | File named prod.keys.txt | Rename to prod.keys | | Keys file inside a subfolder | Move to same folder as hactool or use --keyset | | Using title.keys instead of prod.keys | prod.keys is required; title.keys is different | | Keys from a different console | Keys are console-specific. Dump fresh from your Switch |

If you are diving into the world of Nintendo Switch emulation, modding, or file management, you have likely encountered hactool. It is the industry-standard command-line utility for extracting and decrypting Switch content (NSP, XCI, NCA files).

However, for many beginners, the very first attempt to use the tool ends in frustration with this exact error message: Your query includes the word "top

IOError: prod.keys does not exist

If you are staring at your terminal wondering what went wrong, don't panic. This is the most common hurdle when setting up hactool. In this post, we will explain why this happens and how to fix it step-by-step.

Once you've stopped the error, you should verify the file is valid. Run this command: There is no command called hactool top

hactool --keyset=./prod.keys --keys

If your keys are valid, hactool will print a long list of keys (header_key, area_key, titlekek, etc.) to the terminal. If you see "Failed to locate key," your file is corrupt or from an old firmware.

Before fixing the problem, you must understand the relationship between three critical components:

The error message is literal but slightly misleading. It does not mean hactool is broken. It means: "I am looking for a file named prod.keys in a specific location, and I cannot find it."

Use the --keyset argument to avoid location issues:

hactool --keyset=/full/path/to/prod.keys file.nca

Many automated scripts fail because they assume prod.keys is in ~/.switch/ or the current directory. Modify the script to include the --keyset argument.
