Dell Latitude 5430 Keyboard Not Responding to Input

If your keyboard is outputting the wrong characters try going to the system settings and confirm you are using the intended language/regional keyboard

Dust and debris can collect in keys very easily. If keys are sticking or just hard to press try following the linked guide.

To do this you are going to need a working external keyboard (since your keyboard is not). Turn off your laptop connect your working keyboard. After turning on laptop press F2 button repeatedly to enter BIOS settings. Here you can make sure your keyboard settings are configured correctly.

If all else fails it may be time to replace the keyboard. We recommend following the linked guide in order to do so.
