Method 5 of 5: Troubleshooting a Nonworking Keyboard
Try a different keyboard. Plug another USB keyboard into your computer and see if it works. If the second keyboard works, than something is wrong with the original keyboard. If the second keyboard doesn't work either, then something is wrong with the computer.
Check the connection. If your original keyboard is the problem, there may be an issue with the connection to the computer.
If the keyboard is connected via USB, check that the cable is not frayed and that it is securely plugged into the USB port.
If the keyboard is wireless, ensure that you have the latest drivers installed and that the wireless dongle works. Make sure that the wireless keyboard has fresh batteries.
