Use a tool like LuaMacros or AutoHotInterception to press a key on your second keyboard and record its unique hardware ID string.

MKM intercepts raw input data, assigns PID/VID (Product ID/Vendor ID) to logical groups, and then executes scripts (macros) based on which physical device triggered the event.

Uses Lua scripting, which is beginner-friendly. 2. AutoHotkey (AHK) + Interception Driver

AutoHotkey (AHK) is the gold standard for Windows automation. By combining AHK with a driver framework like Interception , you can differentiate between inputs from your primary and secondary keyboards. This setup lets you create complex, context-aware macros completely free of charge. HID Macros (Free)

The good news is that you do not need to resort to cracking software to harness the power of multi-keyboard macros. A vibrant ecosystem of free, open-source, and reasonably priced legitimate tools exists to solve this exact problem. Below is a curated guide to some of the best alternatives, grouped by their approach and technical complexity.

Ironically, the software you are trying to unlock may not even work. Crackers often disable critical functions or embed bugs that cause system instability. At best, you end up with a non-functional program. At worst, the "crack" is designed to corrupt system files.
