It has five rows and 17 column.

After the rows and column are soldered together, it is time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins from current, preventing them from being shortened. A diode can only allow the current to flow in a single direction, and has a the black band as a visual indicator that indicates the direction current will flow.

A few of the tools that are available at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- may assist customers at the shop or DIY customers in some cases create replacement keys and restore lost saab keys immobilizer data Sanabria says.
