After the rows and column are soldered together after which it is time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins from current and prevent them from getting shorted. A diode only allows current to flow in one direction, and it also has a an indicator in black that indicates which way the current will flow.
Sanabria states that a number of the tools that are sold in auto parts stores, such as the Autel MaxiIM IMM608PRO and IM508 are able to assist customers shopping or DIY users to program replacement keys and restore the immobilizer's data.
