There isn't a standard method to go about it, but you need to think about how to connect and solder each column and row. For this keyboard, there are 5 rows and 17 columns, which means there will be 22 microcontroller wires and pins that you need to connect.
After the rows and column are joined then it's time to connect the key switches. To do this, put a diode on each key switch pin and then solder it. This will shield the key switch pins from current and prevent them from being shorted. The diode allows current to only flow in only one direction. It is equipped with a visible indicator with a black band that indicates the direction in which current will flow.
Sanabria says that some of the tools available in auto parts stores, such as the Autel MaxiIM IM608PRO and the IM508 will assist shoppers or DIY customers to program replacement keys and restore immobilizer information.
