Hello Fred123456lol,
Thank you so much for posting in Microsoft Community.
I appreciate you raising this concern and I understand the need to request for a replacement of your Microsoft Sculpt Ergonomic Keyboard. However, Repair orders are already beyond of our scope here in Microsoft Community since we do not have the necessary tools. For submitting a form, you may refer to this link: Microsoft account | Devices Form PC Accessory.
Wish you all the best and hopefully this helps!
Kind regards,
Rolando S.
