Why Are My Keyboard Keys Typing Double Letters?

So, your keyboard is typing double letters. You may be thinking, why exactly is this happening; There can be several reasons for this. Let’s take a look at some of the possible reasons so that you know the root cause and then choose a viable solution. 

Keyboard’s Physical Problems

Typing double letters isn’t something all keyboards are programmed to do. However, keyboards can get a bunch of issues that might cause them to behave this way.

One of the issues is the keyboard’s physical problems. This can include manufacturing defects and power outages causing the switches and the wires to not work. 

Such problems are much more difficult to fix as compared to other minor issues. That is why it is ideal that you keep a stabilizer connected to your computer and all the peripheral devices whenever you use them. 

Excessive Dust in the Keyboard

Dust might not seem very harmful at the start, but the thing about dust is, it can cause severe problems over time. So if there is a slight amount of dust on your keyboard, you might not bother cleaning it.

But if the dust increases and ends up stacking under the keycaps onto the mechanical switches, the mechanical switches might create problems in sending the signals to the computer.

These signals sometimes might not reach the computer on time and at other times would make the computer type the letters twice, which is the problem we’re facing right now.

Software Issues

Software issues are a major cause of a keyboard typing double letters and numbers. It could be that the keyboard’s drivers are old or broken due to which it is behaving this way and causing the keys to be registered more than once.

There is also the possibility of the keyboard settings being changed. If either of these issues exists within your computer, it is possible that they’ve affected your keyboard, and that is precisely why your keyboard and numpad are typing double letters actually.

Rough Keyboard Usage

Mechanical keyboards might be tough and durable, but keyboards are not designed to be violently used or struck if you’re frustrated or you’re having problems with work. In fact, even a strong press might end up messing up the switch.

If the switches have been damaged due to rough keyboard usage, this issue might introduce itself to your keyboard. Damaged switches can cause double typing or simply stop responding to any kind of instructions and might not even take the signal to the computer for processing.
