Once the rows and columns are soldered, it's the time to connect them to key switches. Solder a diode on each key switch pin. This will shield the pins of the key switch from current and keep them from being shorted. A diode allows current to only flow in one direction. It is equipped with a visible indicator with a black band that shows the direction in which the current will flow.

Do not connect the black cable to the negative terminal on the dead battery as this could trigger an ignition that ignites the gasoline in the engine bay.
