After the columns and rows are soldered, it's the time to connect them to the key switches. To do this, place a diode over each pin of the key switch and solder it. This will protect the pins of the key switch from current and also prevent them from being shorted. A diode only allows the current to flow in a single direction, and has a an indicator in black that shows the direction in which current will flow.
