There isn't a standard method to do it, but you should consider how you will route and solder each column and row. There are 22 microcontroller wires and pins that you can connect to this keyboard. It has five rows and 17 column.

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 shield the pins from current, preventing them from being cut off.

Jump starting the battery

Most people keep a set of jumper cables in their trunk in case of emergency, but jumping a battery on modern vehicles might not be the most efficient option.
