There are 22 microcontroller pins and wires to connect to this keyboard. It has 5 rows and 17 columns.

Once the rows and columns are soldered, it's the time to connect them to key switches. To do this, put a diode on each pin of the key switch and solder it. This will shield the pins from current, preventing them from being shorted. A diode allows the current to flow in a single direction, and has a the black band as a visual indicator that indicates the direction in which current will flow.

Sanabria states that some of the tools offered in auto parts stores, such as the Autel MaxiIM IM608PRO or IM508 will assist shoppers or DIY users to program replacement keys and restore immobilizer information.
