There is no standardized way to accomplish this, but it is crucial to plan the routes you'll use to solder the columns and rows. There are 22 microcontroller pins and wires to connect for this keyboard. It has 5 rows and 17 column.

After the columns and rows are joined after which it is time to connect the key switches. To do this you must place an inverter over each pin of the key switch and solder it. This will protect the pins from current, thus preventing them from being shorted. The diode allows current to only flow in one direction. It comes with a visual indicator with a black band that indicates the direction in which current will flow.

Sanabria states that a number of the tools offered in auto parts stores, like the Autel MaxiIM IM608PRO and the IM508 are able to assist shoppers or DIY customers to program replacement keys and restore the immobilizer's data. The tools connect to the OBD port and automatically guide the customer through the process, making it more simple than replacing the computer inside the vehicle.

Jump-starting the battery

Don't connect the black cable to the negative terminal on the dead battery, as it could ignite an ignition source that ignites gasoline in the engine bay.

Replacement case

Many Saab owners only have one key for their vehicle and if they lose that the cost will be. The reason for this is that it's not cheap to add a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft or other catastrophe it is recommended to have an extra key. Don't purchase a used key even if it's "new."
