Try A New Cable

Replace Batteries

Clean The Keyboard With Canned Air

Clean The Key With A Contact Cleaner

If the canned air technique does not work, use a contact cleaner. However, be cautious while using the contact cleaner as it may damage the other keys surrounding the target key. Some contact cleaners, such as CRC QD contact cleaners, are designed for this purpose.

Once you have the right contact cleaner, remove the keycap and insert the nozzle onto the spray. Now, push the nozzle into the stem and give it two squirts. Sometimes one squirt is also enough—however, don’t squirt more than two times.

Now, move the stem sideways to distribute the spray evenly. Usually, it works with the first attempt. However, you may try it two to three times unless the debris is cleared. Before replacing the keycap, ensure that the contact cleaner has dried completely.

If cleaning the switch also does not work, the button is broken internally. If such is the case, replace the switch with a new one. You may find a new switch for ten cents at a computer hardware store.

If you have some experience with electrical appliances, you should also check the solder joints. Sometimes, the solder joint gets loose or removed from the circuit board. In such a case, you may repair the solder joint yourself or get it to a professional.
