The hardening of the keyboard keys can be solved by cleaning, adjusting or repairing, and it does not necessarily require a new replacement. 1. Clean the key cap and shaft body: Dust and debris accumulation will cause the keys to become tight. You can use a key extractor to clean the key cap and clean the shaft body with a brush, compressed air or alcohol; 2. Check the shaft body to aging or damage: the shaft body may wear after many years of use, so you can try to replace the individual shaft body; 3. The keyboard structure affects the feel: Some keyboard designs themselves cause the keys to be hard, and the shaft body can be lubricated, replace the key cap or adjust the typing posture to improve; 4. Troubleshoot system or driver problems: Occasionally abnormal system will also cause the keys to be stuck. Try to replace the USB port, restart the computer or update the driver to confirm whether it is a hardware problem. In most cases, it can be improved by cleaning, and parts need to be replaced only if severe aging is achieved.

The keyboard keys become hard and the typing feels poor, which affects efficiency. This situation is actually quite common. In most cases, it can be solved through cleaning, adjustment or simple repair, and it does not necessarily have to be replaced. The following methods can help you find the root cause of the problem and deal with it.

1. Cleaning the key cap and shaft is the first step

Over time, dust, debris and even food residues will get stuck under the keys, especially mechanical keyboards are more likely to accumulate dust. This can cause the keys to tighten, rebound slowly, or fail to press.

• You can use a key puller to remove the key caps one by one, rinse them with clean water and dry them.
• Clean the surroundings of the shaft with a small brush or compressed air, especially the cross slider section
• If there is oily or sticky feeling, you can wipe the surroundings of the shaft with a small amount of alcohol

Some membrane keyboards will also accumulate dirt on the bottom, but it is not easy to disassemble. At this time, try to clean it with a blow-drawn and tap.

2. Check whether the shaft body is aging or damaged

If it is a mechanical keyboard, some shafts may suffer from wear and aging of springs after several years of use, resulting in the keys being significantly harder than other keys.

• Commonly used in axes such as blue shafts and tea shafts with a paragraph feeling or a large pressure gauge
• Replacing the shaft body is a way, but it requires a certain amount of hands-on ability (such as using a hot air gun or a welding station)
• If there is only a problem with individual keys, you can try to replace those shafts first, without changing them all

Of course, if you are not sure if it is a shaft problem, you can also try cleaning it first and then test whether the feel has improved.

3. The keyboard structure design or layout affects the feel

Some keyboards are inherently difficult to press, such as:

• Film keyboard sacrifices key stroke and elasticity for lightness
• The keyboard comes with a laptop sometimes feels hard due to structural limitations.
• Some retro mechanical shafts (such as old black shafts) have a large pressure

In this case, it is difficult to completely improve unless the external keyboard is replaced. But you can:

• Try lubrication of shaft body (for mechanical keyboards with removable shafts)
• Use third-party keycaps to change the tap angle
• Adjust typing posture to reduce finger fatigue

4. System or driver exception? Occasionally it will affect the input experience

Although it is not common, sometimes the system misidentifies the keyboard status, which may make you feel that the keys are "stuttered" or "hard to press".

• You can try changing the USB port or restarting the computer to see if there are any changes
• Update motherboard driver or keyboard related driver
• Check for conflicting devices in Device Manager

If the problem disappears after these operations, it means it is not a hardware problem.

Basically, these possible reasons and corresponding solutions are all about them. Most of the time, cleaning can improve a lot. Only when the shaft body is really aging is serious, you need to consider replacing the parts. Those with strong hands-on ability can check step by step, and those who are afraid of trouble can directly change to a new keyboard with a good feel.
