Saab Key Programming

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 to each key switch pin. This will protect the pins that are used for key switches from current and prevent them from being shorted. A diode lets current only flow in one direction. It comes with a visual indicator of a black line that indicates which direction current will flow.

Some of the tools offered at auto parts stores — such as the Autel MaxiIM IM608 PRO and IM508 — could assist customers at the shop or DIY customers in certain instances program replacement keys and restore lost immobilizer data, Sanabria says.
