There isn't a standard method to do it, but you need to consider how you will route and solder each column and row. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller pins and wires to connect.

After the columns and rows are soldered together, it is time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins from current, and prevent them from being shorted. A diode lets current only flow in one direction. It is equipped with a visible indicator that is black, that shows which way current will flow.

Some of the tools you can find at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- may aid shop customers or DIY customers in certain cases create replacement keys and restore lost immobilizer information, Sanabria says.
