There's no standard way to do this, but it is crucial to plan the way you'll route and solder the columns and rows. There are 22 microcontroller pins and wires to connect for this keyboard. It has 5 rows and 17 columns.
Once the rows and columns are soldered, it's time to connect them to key switches. To do this you must place a diode across each pin of the key switch and solder it. This will protect the key switch pins from current and keep them from being shorted. A diode only allows current to flow in one direction, and it has an indicator of black color that indicates which way the current will flow.

Jump-starting the battery
A lot of people keep a set of jumper cables in their trunk for emergency situations, but jumping a battery in newer automobiles might not be the best option. These vehicles have many computers and digital devices that communicate with one another. A surge in voltage when the battery is connected to another one could cause damage to the parts making your car unusable.
Start the vehicle you are using and allow it to run for around two minutes before you connect the cables to the one that is disabled. Attach the red clip to the positive terminal on the battery that is good (it will have "POS" or "+" on it). Attach the other end of the black cable to a clean, unpainted metal surface under the disabled car's hood. The engine block would be a good choice. The black cable should not be connected to the negative terminal of the dead battery. This could result in sparks, which would ignite the gasoline inside the engine compartment.
Once the cables are connected, turn on the vehicle that has been disabled and allow it to run for around five minutes before disconnecting them in reverse order. Keep in mind that the battery on the Saab 9-3 gets recharged when you drive, and it will take a while for the battery to come back to normal. You should invest in a second key fob, when you can.
