Running the keyboard troubleshooter can help detect and fix software issues causing keyboard double typing by scanning for and resolving system errors:
Incorrect language settings can sometimes cause keyboard double typing by misinterpreting input. Adjusting these settings ensures correct keyboard functionality:
Finding the right balance in the repeating key rate settings can help minimize double typing while ensuring that your keyboard responds appropriately to your typing speed.
1- Windows
Changing the key repeat settings in Windows helps control the speed and frequency of keystrokes:
Note: This method applies only to Windows 11, Windows 10, Windows 8.1, and Windows 7.
2- Mac
Adjusting key repeat settings in macOS lets you fine-tune typing response for smoother, error-free input:
The Windows Registry is a hierarchical database that stores low-level settings for the operating system and various applications. Adjusting registry settings related to keyboard response can impact how the system interprets and processes keystrokes.
Issues like double typing may arise from settings such as a too-sensitive repeat rate, low debounce time, encountering "ghost typing", and incorrect registry editor.
You can change the keyboard response in the registry to fix double typing. However, registry modifications can significantly impact your computer. Thus, you should create a backup before proceeding to avoid something going wrong.
Now, you can modify the keyboard registry with these steps.
Note: This method applies only to Windows 11, Windows 10, Windows 8.1, and Windows 7.

For instance, some users still encounter the Corsair keyboard double typing even with the latest drivers. This may indicate a manufacturing flaw in certain models, contact the company to inquire about a refund if the keyboard is under warranty.
Keyboard chattering software helps filter out unintended duplicate keystrokes, reducing keyboard double typing effectively.
1- Windows:
Using Keyboard Chattering software on Windows allows for precise control over input timing:
Note: To auto-run the software at startup, open Run, type shell:startup and place the software’s file in the folder that opens.
2- Mac:
On macOS, Unshaky is a popular app that prevents double typing through delay adjustments:
Note: If the issue continues, consider resetting the NVRAM or consulting Apple Support as it may be a hardware flaw.

Addressing cable-related issues can be a straightforward solution to fix a mechanical keyboard from double typing. If your keyboard's USB cable is in trouble, it can send duplicate signals and lead to erratic behavior, including double typing.
To address potential cable-related problems, you should:
If the double typing issue affects only a few keys, replacing those specific keys may resolve it. For hot-swappable keyboards, key replacement is straightforward:
However, with non-hot-swappable keyboards, you’ll need soldering skills, as the key switches must be desoldered and resoldered for replacement. Ensure you’re comfortable with this process or seek professional help if needed.
A mechanical switch is a key component beneath the keycap, transmitting signals from your typing to your computer's processor. If not all keypresses perform double typing but just a few, those switches might be worn or damaged and need to be replaced.
If you own a hot-swappable keyboard, the process of replacing double-typing switches is straightforward. You just need to make sure you have the right switches for your keyboard.
Here's a quick guide:
Check out our detailed guide to the mechanical switch replacement process.
If your keyboard doesn’t have a hot-swappable feature, you’ll need to solder the mechanical keyboard switches. It’s a bit tricky, but you can refer to the following video for guidance:
On the other hand, it becomes easier if your keyboard has a hot-swappable feature. You can refer to the following video guide to learn how to replace your switches:
For example, if your Razer BlackWidow V4 or similar model is experiencing Razer keyboard double typing, you can replace mechanical keyboard switches to solve the problem. Some Razer BlackWidow keyboards use tactile switches, which can occasionally misfire due to slight misalignments in the switch mechanism. Swapping out the tactile switches for linear ones, or replacing faulty switches altogether, often eliminates repeated key registrations and improves typing precision.

If none of the above solutions show an improvement, it’s time to consider bringing your mechanical keyboard to the repairers or getting a new one. This should be based on your judgments on which ways bring more benefits, both functionally and financially.
Go for a new keyboard if those things are your situation. First, your keyboard warranty is still valid so there is a none-to-little charge. Second, the repair fees are higher than buying a new keyboard. Last, there is a high chance the keyboard double typing will reoccur.
For a good brand new keyboard, it’s best to gather the necessary information before bringing back any new one. Apart from a mechanical keyboard, an optical keyboard or a low-profile keyboard is also a good option for a nice typing experience. Furthermore, if you cannot bear the loud noise coming from pressing down the keys, a quiet keyboard will be your best friend.
There are several reasons behind a double-clicking mechanical keyboard. Getting to know the causes can be a remedy itself as you may think of solutions or know how to prevent it from happening.
Most of the time dust or ‘alien’ objects under the keycaps is the main criminal for your keyboard double typing. The keyswitches cannot run perfectly if there is a thick layer of dust or strange things get in their way. Dust and other debris also cause other problems to your keyboard and degrade your keyswitch longevity.
Cheap switches, old switches, or damaged switches may not allow your typing experiences to happen as normal. A problem within the springs or metal leaves inside a mechanical switch can make the keyboard chattering happen often.
Forgetting to update your keyboard driver can be one of the reasons. An outdated driver can not keep up with your computer and hence, bad communication between the keyboard and a processor happens, or a hole in the keyboard security is born.
If you tend to go hard on your keyboard when typing or drop it several times, the issue of keyboard double typing is likely to happen. Rough handling can cause physical damage to the fragile components of your keyboard, especially if your keyboard is made with cheap and flimsy materials.
