Find out some of the reasons why the keyboard may be faulty
Keyboard errors are very common and have various origins. Most of these problems are due to the excessive dirt that these keyboards may have, such as: dust, debris, and other small elements, cause these failures by damaging the keyboard circuitry.
Another critical factor that causes the device to fail is the humidity. Care should be taken where you place these keyboards, as moisture can cause sulfation in them, causing the current flow to completely shut off.
