After the columns and rows are soldered, it's the time to connect them to the key switches. Solder a diode on each key switch pin. This will protect the pins of the key switch from current and prevent them from being shorted. A diode allows current to flow in one direction, and it comes with a an indicator of black color that indicates which way the current will flow.

Sanabria says that some of the tools available in auto parts stores, including the Autel MaxiIM IM608PRO and the IM508 can assist customers shopping or DIY users to program replacement keys and restore immobilizer data.
