My AOpen KM-935S wireless keyboard wont work. I have changed the batteries in it and still none of the lights will come on and I cant use it. The wireless mouse that is a part of it works fine. Can you help me?

On the receiver for your wireless keyboard and mouse there should be a button that says Connect. What you need to do, is press that button, then press the button on the back of the keyboard that says connect. Depending upon your keyboard, you may have to then connect the mouse afterwards.

Thanks for using FixYa!
