Update your old activation code onto the new PC to complete the setup.

Your language is a bit unclear. Did you take the key from your previous Windows PC? https://www.howtogeek.com/660517/how-to-...nd-prompt/ Are your new PCs using the same Windows 10 or 11 versions? For example, are they both Home editions? Or both Pro editions?
I also referenced that tutorial and applied the command prompt to disable the keyboard on the older machine, which should now function properly, though it hasn't yet.
I understand there are third-party tools that can help retrieve your Windows key. I won't share a link since these might be misused. If you already have the key, consider why it no longer works—updates or Microsoft deactivation could be reasons. It really depends on where you purchased it. From a reputable seller or Microsoft, you might get assistance or an exchange. Unethical sellers usually don’t offer post-purchase help.
EDIT: I previously used OEM keys and they often functioned well. Perhaps your situation is different.
