Hello, good day and thanks for your question. Sorry to know on what happened but you will not be able to purchase a separate dongle for your Microsoft Keyboard Wireless 800 as it is tied to the dongle. By any chance that your hardware is still under warranty?

I cannot seem to find the dongle that goes with my keyboard after moving to my new place, and I can't get my keyboard working. Is there a place where I could buy a replacement dongle? Is there an alternative way to connect it.
