After the columns and rows are soldered together It is now time to connect the key switches. To do this, put a diode on each pin of the key switch and then solder it. This will protect the pins on the key switch from current and keep them from being shorted. A diode can only allow current to flow in one direction, and it also has a the black band as a visual indicator that indicates the direction in which current will flow.
Sanabria states that a number of the tools offered in auto parts stores, like the Autel MaxiIM IM608PRO or IM508 can assist customers who are shopping or DIY users to program replacement keys and restore data from the immobilizer.
