It's not a common way to do it, however, you should consider how you will route and connect each column and row. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller wires and pins to connect.

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 from current, preventing them from being shortened. A diode allows current to only flow in only one direction. It features a visual indicator, a black band, that indicates the direction in which current will flow.

Sanabria says that some of the tools sold in auto parts stores, including the Autel MaxiIM IM608PRO and IM508, can help customers shopping or DIY users to program replacement keys and restore immobilizer information.
