For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller pins and wires to connect.

After the columns and rows are soldered, it's time to connect them to the key switches. Solder a diode on each key switch pin. This will shield the pins from current, thus preventing them from being shorted. A diode can only allow the current to flow in a single direction, and it comes with a the black band as a visual indicator that indicates the direction in which current will flow.

Sanabria states that some of the tools sold in auto parts stores, including the Autel MaxiIM IM608PRO and IM508 will assist shoppers or DIY users to program replacement keys and restore data from the immobilizer.
