Determine Why the Keyboard is Locked

Before trying to unlock the keyboard, it’s important to understand why it’s locked in the first place. Here are some of the most common reasons for a locked keyboard on a Dell laptop:

  • Filter keys are turned on – Filter keys is an accessibility feature that can ignore brief or repeated keystrokes. When enabled, it can make the keyboard appear to be locked.
  • The built-in keyboard is disabled in BIOS – The laptop keyboard can be disabled in the BIOS, blocking input.
  • The laptop is in tablet mode – Laptops with 360 degree hinges may lock the keyboard when flipped into tablet mode.
  • Faulty keyboard or connection – Hardware issues with the keyboard itself or the cable connection could lead to an unresponsive keyboard.

  2. Uncheck the option ‘Turn on Filter Keys’ and click OK.

  2. Navigate to the Configuration tab and select Keyboard.
  3. Change Internal Keyboard from ‘Disabled’ to ‘Enabled’.
  4. Press F10 to save changes and exit BIOS.
  5. The laptop keyboard should now be unlocked after rebooting.

Method 4: Disable Tablet Mode

If your Dell laptop has a 360 degree convertible hinge, it may have locked the keyboard due to entering tablet mode.

To exit tablet mode:

  1. Swivel the screen back into laptop orientation.
  2. Press the tablet mode key, which is usually located above the power button.
  3. The tablet mode status light should turn off, signalling laptop mode is active again.
  4. Check if the keyboard is now unlocked.

Method 5: Update or Reinstall Drivers

Keyboard issues may also arise from corrupted, outdated or missing drivers. Updating the necessary drivers may help:

  1. Open Device Manager using the search bar or control panel.
  2. Expand the ‘Keyboards’ section.
  3. Right click on Standard PS/2 Keyboard and select Update Driver.
  4. Choose to automatically search for updated drivers online and install if available.
  5. You can also try uninstalling the keyboard driver altogether, then restarting the laptop to reinstall the drivers.
  6. If the drivers are up to date, there may be a hardware issue with the keyboard.

Method 6: Test with External Keyboard

To isolate whether the problem is being caused by a hardware fault, connect an external USB keyboard.

  1. Plug the external keyboard into any USB port and wait for it to be recognized.
  2. Try typing on the external keyboard to check if it’s working.

If the external keyboard types normally, then the built-in keyboard most likely has a hardware fault and may need replacement. Contact Dell support for repair options if under warranty.
