Saab Key Programming

Saab cars that were built prior to 1994 have an immobilizer system that is based on codes for keys. In order to add a second key, it requires an entirely new transponder and programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.

Transponder key

It includes 5 rows and 17 column.

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

Sanabria says that some of the tools that are sold in auto parts stores, like the Autel MaxiIM IM608PRO and IM508, can help customers shopping or DIY customers to program replacement keys and restore the immobilizer's data.
