There isn't a standard way to do this, but it is essential to determine the way you'll route and solder the columns and rows. There are 22 microcontroller wires as well as pins to connect to this keyboard. It has 5 rows and 17 column.

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 protect the pins from current, and prevent them from being shortened. A diode can only allow the current to flow in a single direction, and it also has a an indicator in black that indicates the direction in which current will flow.

Sanabria says that some of the tools sold in auto parts stores, like 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.
