You may notice that part of the key or switch is damaged permanently, a more serious problem that will require retiring the keyboard, at least for a while. Sometimes a crumb or bit of debris is keeping the key from properly pressing down on the switch, and blowing it away will fix your problem. If you have a mechanical keyboard or another version that allows you to take off that specific key, do so and inspect what you find underneath.

Otherwise, this problem indicates a hardware problem with that specific key. If that Lock key was accidentally pressed, it would explain why certain number keys aren’t working. For example, if you have a numeric keypad, then you probably have a Number Lock key that can turn it off. Start by looking for any basic reasons why a key may not be working. You can also try visiting Dells keyboard diagnostics page, which may give you a bit more insight into exactly what’s going wrong.

OLD TYPE KEYBOARD DRIVERS
When you log back in, Windows should automatically find and download the right drivers for your keyboard. Right-click to uninstall the drivers, then reboot your computer. Find and expand the Keyboards section to see your current drivers. Search for Device Manager and open its window. If everything checks out, it’s time to head to your keyboard drivers. For wireless models, double-check the Bluetooth connection, and try disabling then re-connecting Bluetooth to see if this makes a difference. For wired keyboards, check to see if it’s plugged into the right kind of USB port: Different keyboards are designed for different USB protocols and may not be compatible with all ports even if they can turn on. If you see the indicator lights turn on but can’t get any response out of the keyboard, take a look at your connection first. The keyboard turns on but won’t function at all

If all else fails, run a virus check: Some malware can interfere with accessories like keyboards and prevent them from working.
