I have msn wireless keyboard and mouse. Mouse works but keyboard does not. Computer recognizes keyboard in add wireless devices. I do not have a keyboard to add as normal as I have no way to enter passkey. Can I get keyboard readded/reinstalled without the use of a keyboard?

There should be a little button on your receiver to initiate a resync. On most keyboards, located on the bottom of your keyboard is also a small button that needs to be pressed as well to initiate a resync.

Then after the keyboard is synchronized, you will need to resync the mouse as well. Press the small button on the underside of the mouse.

Resync keyboard first then mouse.
