Saab Key Programming

There is no standard method to accomplish this, however it's important to plan out the routes you'll use to solder the columns and rows. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins that you need to connect.

After the columns and rows are joined then it's time to connect the key switches. Solder a diode to each key switch pin. This will shield the pins from current and prevent them from being shortened. A diode allows current to flow in one direction, and it comes with a the black band as a visual indicator that indicates the direction in which current will flow.

Don't connect the black cable to the negative terminal on the dead battery, since this could trigger a spark that ignites the gasoline in the engine bay.

Once the cables are connected the vehicle you are not using and allow it to run for around five minutes before you disconnect the cables in reverse order.
