Fix Key Chatter in Mechanical Keyboards [Working Best Solution]

There is no doubt that mechanical keyboards are great for typing and gaming. However, most mechanical keyboards suffer from a very common problem known as key chatter or key bounce. During key chatter, multiple inputs are registered in a single key press which is irritating for both gaming and typing. This means if you press the ‘d’ key then it may get registered as ‘dd’ or ‘ddd’ if it is severe.

Key chattering can arise in single or multiple keys in a mechanical keyboard and it generally arises when the keyboard gets older, but it can also occur in brand new keyboards too. The problem is more pronounced in mechanical keyboards with Cherry MX Clones or Chinese mechanical switches i.e. Outemu, Kailh, etc., but I have seen key chatter in branded mechanical keyboards too (i.e. Corsair, Ducky, etc.) that have original Cherry MX mechanical switches. I have faced this key chatter problem with my Cherry MX Blue keyboard after only a few months of usage.


If your keyboard is under warranty then you can issue an RMA request and get a replacement but it is a bit time-consuming and it is also not guaranteed that the new keyboard will not face this chattering issue. Key chatter can arise due to different reasons and here I am going to list down all the causes of this problem and will tell you how to fix key chatter in mechanical keyboards permanently.

What causes Key Chatter?

Here are the various reasons that can cause key chatter in mechanical keyboards.

Dust – Dust is a major factor contributing to this key chattering problem in mechanical keyboards. Dust can go into the mechanical switches and can cause the malfunction of switches. So, it is advisable to keep your keyboard away from dusty environments and keep it covered when not in use.

Faulty Switches – Faulty and Defective mechanical switches are another major cause of key chattering in mechanical keyboards. The switches may become faulty after some time or it can also be a manufacturing defect straight from the company or manufacturer. I must say that the quality of mechanical switches is getting doubtful these days as I have seen many cases of bad switches lately.

Rough Usage – Well if you type hard or play hard then you can be damaging your mechanical switches with extra force, and this may cause them to function improperly leading to the most common problem which is key chatter.

Temperature – Well this is not a major factor but if you keep your keyboard in hot and humid conditions then mechanical switches may not perform normally and this can lead to key chattering.

How to Fix Key Chatter in Mechanical Keyboards

Here are some of the common ways by which you can try to fix the key chatter in mechanical keyboards, but I do not recommend them, especially if your keyboard is new and under warranty.

Compressed Air – You can try to use compressed air to clean the mechanical switch and to make it work again normally. Remove the key cap, press the switch, blow air using a compressed air can or duster in the switch, and repeat this process two or three times. Well, it is not guaranteed that the switch will come back to normal functionality eliminating chatter but it can work sometimes if the chattering is due to dust-related issues.

Tapping it constantly – Tap the defective key hard multiple times and see if the problem goes away. Some users have reported solving key chatter issues like this but I do not recommend this method as you can cause more harm to the switch and make the problem worse. Not Recommended but for knowledge purposes.

Using Contact Cleaner Spray – You can spray contact cleaner sprays like WD40 Specialist Contact Cleaner on the mechanical switch to resolve the issue. To spray, remove the mechanical switch keycap, press the switch, and spray the contact cleaner into the switch liberally. Allow the switch to dry and then tap the switch a couple of times. In quite several cases, this technique fixes the key chatter issue for a long time.

Replace Faulty Switch – Replace the faulty switch with a new one and your problem should go away. This method is not for everyone, as it requires opening up your keyboard, de-soldering, and soldering the switch, which only experienced users who have good technical know-how, can do. You can buy Cherry MX mechanical switches online but other Cherry MX clone switches can be hard to find. This is also a very risky procedure and should not be attempted by a noob or novice user, otherwise, you may end up damaging your whole keyboard.

Replacement (RMA) – You can issue an RMA request and get a replacement if your keyboard is under warranty period. Well, this sounds good but you will never know that the replacement keyboard is completely free from key chattering because this problem may arise in the newly replaced keyboard too after some time. It is a very time-consuming process too and can hamper your productivity. So, it is up to you whether you want to take this chance or not, because it may happen that the replacement piece may come with bigger problems compared to the older one.

Best Way to Fix Key Chatter in Mechanical Keyboards

This method works with any number of keys that have chattering or double typing issues. This method fixes the key chattering problem on the software side and it is very flexible and easy to implement. Also, this solution works with every mechanical keyboard with any switch type.

Follow the steps mentioned below to fix the chattering issue with your mechanical keyboard.

Step 1. Download the Keyboard Chattering Software from here.

Step 2. Unzip it and start the Keyboard Chattering Software executable file from the folder.

Step 3. Here, in the Config menu, Enable Chattering Filter, and in Threshold change the value from 50 to 90 to completely fix the key chatter issue. Click on Apply and minimize the software. Now, this software will delete any duplicate inputs or repeated characters arising from key chattering. It can automatically filter key chattering without interfering with your work. I find 90ms to be the sweet spot for removing duplicate inputs. However, if the key chatter is too serious or aggressive on your mechanical keyboard then you can set the Threshold value to 40 or even lower depending on the severity of key chattering you have.


Step 4. To run this software automatically on Windows Startup go to Start Menu->Run-> shell:startup and then place the executable file of the Keyboard Chattering Software in C:\Users\<YOURUSERNAME>\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup
