There are 22 microcontroller pins and wires to connect for this keyboard. It includes 5 rows and 17 column.

After the columns and rows are soldered, it's the time to connect them to key switches. Solder a diode on each key switch pin. This will protect the pins from current, and prevent them from being shorted.

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