It has five rows and 17 column.

Once the rows and columns are soldered, it's the time to connect them to key switches. Solder a diode on each key switch pin. This will shield the pins that are used for key switches from current and stop them from being shorted. A diode lets current only flow in only one direction. It features a visual indicator that is black, that shows which way current will flow.

Sanabria states that a number of the tools that are sold in auto parts stores, including the Autel MaxiIM IM608PRO and the IM508 can assist shoppers or DIY customers to program replacement keys and restore data from the immobilizer.
