Recently a company I work for changed provider for Office 2010 and the key that is listed in the KMS-server is wrong.
How do I change the current key to the new one?

As marked above, the product key is wrong, this is what I need to change.
Just input the desired product key, this will replace the current product key with the new key:

Manually install the Office 2010 KMS host key and activate
If you want to manually enter the Office 2010 KMS host key and activate it, use the slmgr.vbs script. For more information, see
Configure the Office KMS host later in this article.
Open an elevated command prompt, and then run the following commands:
slmgr.vbs /ipk <NEW Office 2010 KMS host key>
slmgr.vbs /ato <Office 2010 activation ID>
The Office 2010 activation ID is bfe7a195-4f8f-4f0b-a622-cf13c7d16864.
