There is no doubt that mechanical keyboards are great for typing and gaming. However, most of the 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 very irritating and annoying for both gaming and typing. This means if you press ‘d’ key then it may get registered as ‘dd’ or ‘ddd’ if it is severe.
Key chattering can arise in a 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 are having original Cherry MX mechanical switches. I personally have faced this key chatter problem with my Cherry MX Blue keyboard after only few months of usage.
If your keyboard is in warranty then you can issue a RMA request and get a replacement but it is a bit of 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 on 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 in a major factor contributing to this key chattering problem in mechanical keyboards. Dust can go in the mechanical switches and can cause 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 is 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 personally do not recommend them especially if your keyboard is new and under warranty.
Compressed Air – You can try use compressed air to clean the mechanical switch and to make it work again normally. Remove the key-cap, press the switch and 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 issue.

Tapping it constantly – Tap the defected key hard multiple times and see if the problem goes away. Some users have reported to solve key chatter issue like this but I do not recommended this method as you can cause more harm to the switch and making the problem worse. Not Recommended but for knowledge purpose.
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 it. 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 attempted by a noob or novice user, otherwise you may end up damaging your whole keyboard.
Replacement (RMA) – You can issue a 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 new 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 that 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.
