However, if just one key stops working while the rest work fine, it is more likely to be a problem with that particular switch. For example, if you are A key is not working while the rest work fine, it is more likely to be a problem with that specific switch. If the keyboard does not work, it is likely a connection or driver problem. The following is a list of potential causes for a key on a mechanical keyboard to cease functioning:
- The connection to the PC is not functioning correctly.
- There is a problem on the inside with a switch.
- There is an issue with a button.
- There is garbage accumulated beneath the keycap.
If you are using a mechanical keyboard and are experiencing issues with keys not responding, you should attempt each of the following solutions in the order they are listed. You may skip any of these options that don't apply to the keyboard you're using if there's one here that doesn't work.
Ways To Fix Unresponsive Keyboard Keys:
- To restart the keyboard, unplug it and then plug it back in. it is a simple remedy that takes no time. After you have plugged in the keyboard, test each key to see whether it works. If it does, then you are finished.
- You might also try a new cable. Suppose your keyboard is linked to your computer by a physical connection. In that case, you should try switching to a new thread and inserting it into a different USB port on your computer if you are experiencing connectivity issues. If you are experiencing issues and are utilizing Bluetooth, you may check to see if the problem can be solved by connecting using a cable. If it does, there is likely an issue with the Bluetooth driver on your device.
- There is a possibility that the connection is occasionally disconnecting. Put in a new set of batteries and see if it fixes the problem of dead key; it's worth a shot.
- It's time to clean the keyboard. The keycaps of the keys that aren't responding may be becoming caught in debris. To begin, experiment by using bottled air to blow between the keycaps. If it does not solve the problem, you must take off the keycaps and clean the keyboard with bottled air.
- Remove the fuse from the switch that isn't responding. Remove the keycap from the not responding button by prying it off, flip the keyboard over and use bottled air to clean out the switch. If it solves the problem, you should probably clean the keyboard now so that you won't have the same issue with different controls in the future.
- Employ the use of a contact cleaner. Turn off the power to your keyboard, take out the batteries, and then transfer the keyboard to a place with plenty of fresh air. After removing the keycap, you should place the nozzle of the contact cleaner or the straw into the stem of the key switch. After applying one or two squirts of contact cleaner, move the switch stem in all directions, including up, down, left, right, and diagonally. After that, give the contact cleaner sufficient time to dry entirely before restoring the keycap and determining whether or not the key still operates.
- Examine the solder joints for quality. If your keyboard contains soldered switches, it's possible that one of the solder connections on one of the switches has failed. You may resolve the issue by mending the solder joints. If the solder has detached from the circuit board or the switch contacts seem loose.
- Change out the toggle switch. Changing the button is often the last resort that successfully resolves problems of this kind. You will need to desolder and remove any controls that have been soldered, and then you will need to solder in replacements. Hot-swappable switches may be removed from their housings using the appropriate tool, and then a new button can be inserted in its place without the need for soldering.
- It's time to get a new keyboard. Changing the switch is the first step in troubleshooting, but if it doesn't work, there may be a more severe issue with the keyboard itself.
Methods For Restoring Functionality
When a key on a mechanical keyboard stops working, the problem may be fixed by changing the switch that controls that key. If you have a keyboard that supports hot-swapping, you may remove the button using the proper tool and replace it with a new one by simply snapping it into place. Even if it doesn't happen often, hot-swappable switch sockets might eventually get worn out.
