There isn't a standard method to do it, but you need to plan how to get a saab replacement key to route 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 to connect.

After the columns and rows are soldered, it's time to connect them to key switches. Solder a diode to each key switch pin. This will protect the pins from current, thus preventing them from being cut off. A diode allows current to only flow in one direction.

Don't connect the black cable to the negative terminal on the dead battery as it could ignite an ignition source that ignites gasoline in the engine bay.
