It's not a common way to go about it, however, you should determine how to route and connect each column and row. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller pins and wires to connect.

Once the rows and columns 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 and prevent them from getting shorted. A diode only allows the flow of current to be in one direction, and it comes with a the black band as a visual indicator that indicates the direction current will flow.

Some of the tools available at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- may help customers in the shop, or even DIY customers in certain cases replace keys in the program and restore lost immobilizer data, Sanabria says.
