Fallout 4 Keyboard Not Working is a problem gamers have had to deal with every once in a while. The keyboard will just cease working completely during the Fallout 4 gameplay. The inability to use the keyboard, and occasionally the mouse, may be caused by software conflicts or outdated drivers. 

In most cases, players have been able to resolve the problem by restarting the Fallout 4 game. Reconnecting the keyboard may also help fix some temporary keyboard problems. In other cases, restarting the game or reconnecting the keyboard may not fix the issue. 

If you are in such a situation, the more advanced solutions discussed in this guide will come in handy. The guide also explains the various causes of the Fallout 4 keyword not working issue, and some quick fixes for the problem. 

What Caused the Keyboard not to Work in Fallout 4?

When not using the gamepad, you will need to use the keyboard to play and to alter various settings on the Fallout 4 game. A considerable number of Fallout players have had their keyboards fail during the gameplay. 

When this happens, you will be unable to use the keyboard while playing Fallout 4 until the problem is resolved. The inability to use the keyboard on Fallout 4 may be caused by several things, including: 

App Overlay 

Some of the applications you may have installed in your computer are known to overlay the Fallout 4 game. This prevents the game from running as it should and may even cause the keyboard to be unresponsive. 

Some of the applications commonly associated with this problem include Overwolf and Steam. If this is the cause of your keyboard problem, you should consider disabling the problematic App, as discussed later in this guide. 

Fallout 4 Limiting You to One Input Method at a Time 

The game is known to prevent players from using multiple input devices. For instance, using both the keyboard and mouse may be considered to be cheating in the Fallout 4 game. If the game suspects you to be cheating, it will automatically deactivate the keyboard, rendering it unusable in the gameplay. 

This error may also occur when you have the controller connected to the console or just installed as a device. Again, using a gamepad alongside the keyboard to play the game may also be detected as cheating, resulting in the same problem. 

If this is the problem, the solution would be to remove all devices, restart the computer, and then install the keyboard.
