Saab Key Programming
Saab cars built since about 1994 have an immobilizer system made up of coded keys. The addition of a key requires a new transponder and special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

There's no standard way to accomplish this, however it is essential to determine the routes you'll use to solder the rows and columns. For this keyboard, there are five rows and 17 columns. This means there will be 22 microcontroller pins and wires to connect.
After the columns and rows are soldered, it's time to connect them to the key switches. To do this, you need to place a diode over each pin of the key switch and then solder it. This will shield the pins of the key switch from current and also prevent them from being shorted. A diode allows current to only flow in only one direction. It features a visual indicator, a black band, that shows which way current will flow.

Do not connect the black cable to the negative terminal of the dead battery, since it could spark an ignition that ignites the gasoline in the engine bay.
