This chip has an unique code that is encoded into the car's system to identify it.

The car will recognize the saab car key keyfob, and allow it to be turned on. The car will only recognize the key fob if it has an unmodified chip and Saab Ignition Key programmed to match. If not, the car will refuse to accept the key and will not start.

There's no standard way to do this, but it is essential to determine how you will route and solder the rows and columns. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins to connect.

After the rows and column are joined It is now time to connect the key switches. Solder a diode on each key switch pin. This will protect the key switch pins from current and prevent them from being shorted. A diode allows the flow of current to be in one direction, and it has the black band as a visual indicator that shows the direction in which current will flow.

Sanabria states that a number of the tools that are sold in auto parts stores, such as the Autel MaxiIM IM608PRO or IM508 can assist shoppers or DIY users to program replacement keys and restore the immobilizer's data.

Don't connect the black cable to the negative terminal on the dead battery, since it could spark a spark that ignites the gasoline in the engine bay.
