可能没有比锁定键盘更令人沮丧的故障了。让整个 PC 死机是一回事，而让您的键盘变得无响应则是另一回事。
在笔记本电脑上情况更糟，因为键盘不仅仅是可以轻松更换的廉价有线外围设备。不过，没有必要恐慌。
锁定键盘可能是由硬件故障以外的多种因素造成的，其中大部分都很容易修复。以下是在Windows 10(Windows 10)和Windows 11中让锁定的键盘再次工作的所有方法。
为什么键盘会被锁定？
您的键盘可能没有响应的原因有多种。筛选键(Filter Keys)可能已激活，设备可能在过时的驱动程序上运行，或者键盘可能未正确连接
。
然后还有硬件问题需要考虑，从无线键盘中的电池耗尽到物理卡住的键。当然，键盘总是有可能只是简单地完成并且您需要更换。
您可以使用屏幕键盘(with the on-screen keyboard)一段时间，它可以让您单击虚拟键盘上的按钮。但是，最终，您需要找到问题的根源并解决它。
修复 1：确保键盘实际上已锁定(Keyboard Is Actually Locked)
在您急于尝试解锁锁定键盘的方法之前，请花几分钟时间确定这是否真的是问题所在。您可能会将挂起的计算机与锁定的键盘混淆。
尝试使用鼠标（或笔记本电脑上的触摸板），看看指针是否移动。如果它的运动有口吃，您正在处理一台无响应的计算机。只有当鼠标正常工作时，您才知道是您的键盘锁定了。
您可能还会看到其他键盘问题，而不是锁定的键盘。例如，重复键(Repeating keys)会使打字变得非常困难，即使键盘在技术上可以正常工作。
修复 2：重新启动计算机
您可能已经这样做了，但值得重复。重新启动 PC 通常可以解决大多数临时问题，例如无响应的外围设备或内存错误。
请记住，使用Shutdown选项可能还不够。大多数现代计算机只是保存它们的内存状态并在关闭后重新加载它们以提高启动速度。
您必须明确使用电源选项中的(Power)重新启动(Restart)选项，以确保计算机实际关闭。
修复 3：关闭过滤器键
锁定键盘的第一个原因是过滤键(Filter Keys)功能。这是一项辅助功能，旨在让手颤的人更容易打字，过滤键(Filter Keys)经常会在毫无戒心的用户最不怀疑的时候触发，从而绊倒毫无戒心的用户。
它的工作方式很简单：按住Shift键超过 8 秒会弹出一个对话框，用于启用Filter Keys。如果您不小心按了空格键(Spacebar)或选择“是”，它就会生效。
当过滤键(Filter Keys)处于活动状态时，所有短按键都将被忽略。只有按住几秒钟的键被注册为输入。这使得它看起来好像计算机键盘已被锁定。
修复它很简单。除非您打算使用此功能，否则您只需关闭(turn off Filter Keys)计算机上的过滤键即可。这可以在“轻松(Ease)访问”(Access)设置下找到，以及其他辅助功能（如粘滞(Sticky)键）。
- 要禁用过滤键(Filter Keys)，请通过单击齿轮图标从开始菜单(Start Menu)打开设置。
- 选择辅助功能选项卡。
- 向下滚动(Scroll)并单击键盘(Keyboard)以打开与其相关的所有选项。Filter Keys选项与(Filter Keys)Sticky Keys一起位于顶部。禁用切换以将其关闭。
修复 4：重新连接键盘
将键盘与计算机重新连接显然不是笔记本电脑键盘的选择，但它可以为外接键盘解决问题。由于连接不正确，键盘输入无法注册是很常见的。
对于有线键盘，这意味着拔下USB电缆并重新插入。在无线键盘中，您需要对接收器加密狗执行相同的操作。
尝试使用不同的USB端口，因为频繁使用的端口可能已松动或出现故障。特别是如果您使用的是某种USB集线器，问题可能出在集线器上而不是键盘上。
修复 5：更换电池
这不适用于有线键盘，因为它们从 PC 本身获取电力。但是无线键盘在电池上运行，并且可能仅仅因为电池没电而无法工作。
这样的键盘还有一个开/关开关，您可以切换它以检查它是否开始工作 - 电池电量不足通常会在再次像这样通电时为您提供更多汁液。这表明您需要更换电池。
修复 6：检查卡住的键
与完全失效的键盘相比，有一些故障键(a few malfunctioning keys)更为常见。通常发生的情况是某个特定键卡在按下的位置，从而阻止任何其他键注册。
仔细检查你的键盘，检查每个键，看看它是否在物理上工作。钥匙可能会损坏，或者由于灰尘或碎屑而被卡住。在这种情况下，您需要做的就是清理污垢以释放钥匙。
如果您不小心将液体溅到了键盘上，清洁它需要更多的工作(cleaning it is going to take more work)。您必须将其拆开并清洁内膜，使用酒精棉签擦去任何粘性残留物。
修复 7：重新安装设备驱动程序
基本输入设备（如键盘）的驱动程序默认安装在您的计算机上，因此无需更新它们。但有时这些驱动程序会意外损坏或弄乱，导致键盘锁定。
重新安装键盘驱动程序是解决这种情况的方法。您甚至不需要在线搜索合适的驱动程序——只需卸载键盘并重新启动计算机即可(simply uninstall the keyboard and restart the computer)。Microsoft Windows将自动为您安装适当的驱动程序。
- 要重新安装键盘驱动程序，请从控制面板(Control Panel)打开设备管理器(Device Manager)。您也可以从“开始”菜单(Start Menu)中搜索它。
- 在这里，您将看到连接到计算机的所有硬件设备的列表。展开键盘(Keyboards)部分。
- 右键单击(Right-click)有问题的键盘并选择卸载(Uninstall)设备。
- 将出现一个对话框，确认您的选择。选择卸载(Uninstall)按钮继续。
- 重新启动计算机。Windows操作系统会自行重新安装键盘驱动程序
。
如果您不想卸载设备，可以使用
设备管理器(Device Manager)中的更新驱动程序(Update Driver)选项。
解锁锁定键盘(Locked Keyboard)的最佳方法是什么？
由于多种原因，键盘可能会被锁定。因此，没有一种方法可以解锁所有锁定的键盘——适用于一个系统的方法可能不适用于另一个系统。因此，您必须采取散漫的方法。
首先禁用Filter Keys，然后正确地重新启动计算机。如果这不起作用，请继续使用键盘本身。更换电池（用于无线键盘），检查是否有卡住的键，然后将其插入不同的USB端口。
在这个阶段，您已经排除了键盘无响应的所有常见因素。您可以尝试重新安装驱动程序，但这很少会出现问题。如果您的键盘仍然无法正常工作，那么是时候更换它了。
How to Unlock a Locked Keyboard in Windows
There is рerhaps no glitch more frustrating than a locked-up keyboard. It’s one thing to have the whole PC freeze up, and quite another to just have your keyboard become unresponsive.
It’s even worse on a laptop since the keyboard isn’t just a cheap wired peripheral you can replace easily. Still, there is no need to panic.
A locked keyboard can result from a variety of factors other than a hardware fault, and most of these are quite easy to fix. Here are all the methods for getting a locked keyboard working again in Windows 10 and Windows 11.
Why Does a Keyboard Get Locked?
There are a variety of reasons why your keyboard may not be responsive. The Filter Keys may have been activated, the device might be running on outdated drivers, or the keyboard just might not be connected properly.
Then there are hardware issues to consider, from a dead battery in a wireless keyboard to physically stuck keys. And of course, it’s always possible that the keyboard is simply done for and you need a replacement.
You can get by for a while with the on-screen keyboard, which lets you click buttons on a virtual keyboard. Ultimately, however, you need to find the root of the problem and fix it.
Fix 1: Ensure the Keyboard Is Actually Locked
Before you rush into trying out methods to unlock a locked keyboard, take a few minutes to determine if that’s really the issue. You might be confusing a hung computer with a locked keyboard.
Try using your mouse (or the touchpad on a laptop), and see if the pointer moves or not. If there is stuttering in its movement, you are dealing with an unresponsive computer. It’s only if the mouse works properly that you know it’s your keyboard that has locked up.
You may also see other keyboard issues rather than a locked keyboard. Repeating keys, for example, can make typing very difficult, even though the keyboard is technically working.
Fix 2: Restart the Computer
You have probably done this already, but it bears repeating. Restarting the PC usually fixes most temporary issues, such as unresponsive peripherals or memory errors.
And keep in mind that using the Shutdown option might not be enough. Most modern computers simply save their memory states and reload them after a shut down to improve booting speed.
You have to expressly use the Restart option from the Power options to ensure the computer actually turns itself off.
Fix 3: Turn Off Filter Keys
The number one reason for a locked keyboard is the Filter Keys function. This is an accessibility feature meant to make typing easier for those with hand tremors, Filter Keys frequently trips up unsuspecting users by triggering when they least suspect it.
The way it works is simple: holding the Shift key for more than 8 seconds brings up a dialog box for enabling Filter Keys. If you accidentally hit the Spacebar or select Yes, it goes into effect.
While Filter Keys is active, all short keypresses are ignored. Only keys held down for a few seconds are registered as input. This makes it seem as if the computer keyboard has been locked up.
Fixing it is simple. Unless you plan on making use of this feature, you can just turn off Filter Keys on your computer. This is found under Ease of Access settings, alongside other accessibility features like Sticky keys.
- To disable Filter Keys, open Settings from the Start Menu by clicking on the gear icon.
- Select the Accessibility tab.
- Scroll down and click on Keyboard to open all options related to it. The Filter Keys option is right there at the top, along with Sticky Keys. Disable the toggle to turn it off.
Fix 4: Reconnect the Keyboard
Reconnecting the keyboard with the computer is obviously not an option for a laptop keyboard, but it can do the trick for external keyboards. It’s common for keyboard input not to register due to an improper connection.
For a wired keyboard, this means unplugging the USB cable and inserting it again. In a wireless keyboard, you need to do the same with the receiver dongle.
Try using a different USB port as well, since the port used heavily might have gotten loose or could be malfunctioning. Especially if you are using a USB hub of some sort – the problem might lie in the hub rather than the keyboard.
Fix 5: Replace the Batteries
This one is not applicable to wired keyboards, as they draw power from the PC itself. But a wireless keyboard runs on cells, and might not be working simply because a battery has died.
Such keyboards also have an on/off switch which you can toggle to check if it starts working – a flagging battery usually gives you some more juice when powered on like that again. That’s a sign that you need to change the batteries.
Fix 6: Check for Stuck Keys
It’s more common to have a few malfunctioning keys than a completely dead keyboard. What usually happens is that a particular key gets stuck in the depressed position, preventing any other keys from registering.
Carefully go over your keyboard, checking each key to see if it is physically working. A key might be broken, or simply stuck due to dirt or debris. Cleaning out the dirt to free the key is all that you need to do in this situation.
If you have accidentally spilled a liquid on your keyboard, cleaning it is going to take more work. You’ll have to take it apart and clean the inner membrane, using an alcohol swab to wipe away any sticky residue.
Fix 7: Reinstall Device Drivers
Drivers for basic input devices like keyboards come installed on your computer by default, making it unnecessary to update them. But sometimes these drivers get corrupted or messed up by accident, leading to a locked keyboard.
Reinstalling the keyboard drivers is the fix for such cases. You don’t even need to search for the appropriate drivers online – simply uninstall the keyboard and restart the computer. Microsoft Windows will automatically install the appropriate drivers for you.
- To reinstall the keyboard drivers, open the Device Manager from the Control Panel. You can also search for it from the Start Menu.
- Here you will see a list of all hardware devices connected to your computer. Expand the Keyboards section.
- Right-click on the problematic keyboard and select Uninstall device.
- A dialog box will appear, confirming your choice. Select the Uninstall button to continue.
- Restart the computer. The Windows operating system will reinstall the keyboard driver by itself.
There is also an Update Driver option in the Device Manager that you can use if you don’t wish to uninstall the device.
What Is the Best Way to Unlock a Locked Keyboard?
A keyboard can be locked due to a multitude of reasons. As such, there is no one method to unlock all locked keyboards – what works on one system might not be the right solution for another. So you have to go for a scattershot approach.
Start by disabling Filter Keys, and properly restarting the computer. If that doesn’t do the trick, move on to the keyboard itself. Replace its batteries (for a wireless keyboard), check for stuck keys, and plug it into a different USB port.
At this stage, you have ruled out all common factors of an unresponsive keyboard. You can try reinstalling the driver, though that’s rarely the issue. If your keyboard still isn’t working, it’s time to replace it.
