Whether it is the laptop’s own keyboard or an external independent keyboard, the keyboard is locked or frozen, your keyboard is not typing and you can’t type anything. This article will introduce several common causes of keyboard lock and corresponding solutions.

Why is my keyboard locked?

There are usually many reasons why the keyboard is locked. Accidentally pressing a special key, enabling some special functions, or generating two or two errors, etc., will cause the keyboard won’t type. The following will list the most common 5 reasons for the keyboard to fail to type.

  1. The keyboard-specific lock key was pressed
  2. Turn on the Windows filter key function
  3. The keyboard and the computer are connected incorrectly
  4. The keyboard is broken or out of power
  5. Keyboard driver or system error

How to unlock a locked keyboard?

1.The keyboard-specific lock key was pressed

First of all, you need to confirm whether the keyboard lock is the entire keyboard locked or only the right number key area. The confirmation method is very simple. There is no response when pressing the buttons on the right number area, but there is a response when pressing the letters and characters buttons in other areas, which means that only the buttons in the number area are locked. Or observe the index on the upper right of the keyboard, if the first lock indicator does not light up, it also means that the number area keys are disabled. If you can’t type anything, all keys are disabled.

  • “Numlock” (workaround for disabling numeric keys)

    How to unlock the keyboard

After pressing the first key “Numlock” in the number key area, the indicator light of the first lock key above the “Numlock” key will light up, which means that you have unlocked and enabled the number key area, and then you can use them normally. Press “Numlock” to repeatedly disable or enable the number key area.

  • “Fn” + lock key (workaround to lock the entire keyboard)

If your entire keyboard is locked, then you may have pressed the lock key.

Not all keyboards have the function of locking keys. First of all, this workaround requires that your keyboard has this function. The usual lock key function is triggered by pressing “Fn” + the key with a small lock at the same time, and pressing the “Fn” key and the key with a small lock again can unlock the keyboard.

2.Turn on the Windows filter key function

If your keyboard doesn’t recognize the pressed keys at all, then you may have the Filter Keys feature enabled. The filter key function refers to the ability to make Windows ignore short or repeated keystrokes and slow down the keyboard repetition speed. Using this function, users can set the computer to a keystroke speed that suits their habits. But in the first two startups, you need to press and hold the button for 1-2 seconds each time to enter a character. For most users who only last less than 0.1 seconds each time the button is pressed, no matter how much you press the keyboard, there is no response.

Press and hold the “Shift” button for 8 seconds (to turn off the Windows filter key function)

To enable or disable the Windows filter key function on Windows 10, 11, you can press and hold the “Shift” button for 8 seconds to achieve. Additionally, you can manage Mouse Keys functionality with the following steps:

  1. Click the windows icon or press the “windows” + “X” key,
  2. Click “Settings” in the window
  3. Click “Accessibility” in the window
  4. Click “Keyboard”
  5. Find “Filter Keys” and click the button at the back to turn it on or off. Click the arrow at the back and you can choose whether to enable its shortcut keys, or change a series of its parameters

Tips: The above two methods work for both external keyboards and laptop keyboards.

3.Computer connection error

The keyboard is connected to the PC computer incorrectly. At this time, you can unplug the USB interface of your keyboard and plug it into the computer to see if it can work normally again. If you are a wireless Bluetooth keyboard, press the “windows” + “I” keys to enter the setting interface, click “Bluetooth and other devices”, click “Devices”, and then find the Bluetooth name of the keyboard in the device drop-down box that appears, and click the back “⋮”, then click “Remove Device”. Next, click “Add Device” at the top, select “Bluetooth”, and select your keyboard model in the Bluetooth list that appears to connect.

4.The keyboard is broken or out of power

If the keyboard still does not work properly through the third method, it may be that the keyboard is broken or out of power. Replaceable battery The keyboard is replaced with a new pair of batteries, the rechargeable battery is fully charged, and then connected to the computer equipment. If it works normally, then it is the reason for the power outage.

If it still doesn’t work, then connect the keyboard to another computer that is working properly. If it doesn’t work on other computers, then the keyboard is broken, and you have to buy a new keyboard; if it works on other computers, it should be that your computer’s keyboard driver is broken or a system error.

5.Keyboard driver or system error

If it works normally on someone else’s computer but doesn’t work on your own, it may be caused by a driver or system error.

First, you can try restarting your computer. After all, it is always said that restarting solves 90% of the problems, and reinstalling the system solves 99% of the problems, which always makes sense. After restarting, check whether the keyboard works normally. If it works normally, no other steps are required. If it does not work normally, please reinstall the keyboard driver on Windows 7/10/11 according to the following steps.

  1. Right-click “This PC” on the desktop and select “Manage”.
  2. Then click “Device Manager” in the list on the left.
  3. Then click the “Keyboard” option on the right.
  4. Right-click your keyboard driver, and then click “Update Driver”.
  5. Then select the “Search for drivers automatically” option to check for updates.
  6. Wait for the driver to be reinstalled and then exit.

Reconnecting the keyboard after installation completes works fine.
