Here are some possible reasons why a keyboard may not be working and some suggestions for what to do:
Loose connection
Check to make sure that the keyboard is properly connected to the computer or device it's supposed to be working with. If it's a wired keyboard, make sure the USB cable is securely plugged in. If it's a wireless keyboard, check the batteries and the connection between the keyboard and the receiver.
Driver issues
Sometimes a keyboard may stop working because of driver issues. Try updating the keyboard driver through the device manager or reinstalling the driver.
Physical damage
If the keyboard has been physically damaged, such as from a spill or a drop, it may stop working. If liquid got into the computer, see what to do first when a computer got wet before trying to use it again.
Software issues
Sometimes a keyboard may stop working because of software issues, such as a conflicting program or a virus. Try running a virus scan or closing any conflicting programs.
Faulty keyboard
If none of the above solutions work, it's possible that the keyboard itself is faulty. In this case, you may need to replace the keyboard or have it repaired.
Basic checks
Check the connection.
Restart your computer or device.
Check for driver updates or reinstall the driver.
Check for physical damage.
Run a virus scan or close conflicting programs.
Try using a different keyboard or have the keyboard repaired.
