It's not a common way to go about it, but you must consider how you will route and connect each column and row. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller wires and pins that you need to connect.

After the columns and rows are soldered together then it's time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins of the key switch from current and keep them from being shorted. A diode allows the flow of current to be in one direction, and has a the black band as a visual indicator that shows the direction in which current will flow.

Sanabria says that a few of the tools that are sold in auto parts stores, such as the Autel MaxiIM IM608PRO or IM508 will assist customers who are shopping or DIY users to program replacement keys and restore the immobilizer's data.
