The car will recognize the Saab keyfob, and allow it to turn on. But, it's only able to do so if the key fob has an unmodified chip that has been programmed to match the original. Otherwise, the car will reject the key and not start.

The next step is to connect the column and row wires to the microcontroller. This is the toughest component of the project and will require a lot of soldering. It's not a common way to go about it, however, you should determine how to route and solder each column and row. There are 22 microcontroller wires as well as pins to connect to this keyboard. It has five 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 a diode over each pin on the key switch and then solder it. This will shield the pins from current, thus preventing them from being shortened. The diode allows current to only flow in one direction. It is equipped with a visible indicator with a black band that shows the direction in which the current will flow.
Sanabria states that a number of the tools offered in auto parts stores, such as the Autel MaxiIM IM608PRO or IM508, can help customers shopping or DIY customers to program replacement keys and restore immobilizer data.

Jumpstarting the battery
Most people keep the set in their trunks to jump-start their car in case of emergency, but it might not be the best option for vehicles with newer technology. These vehicles are equipped with a number of digital and electronic devices that communicate with one another. A surge in voltage while a battery is hooked up to another could cause damage to these components and render your car unable to drive.
Connect the cables to the vehicle working. Let it run for two minutes. Attach the red clip to the positive terminal of the battery that's good. (It will say "POS" or "+".) Attach the other end to a clean unpainted metal surface under the hood of the damaged vehicle. The engine block is a great alternative. Do not connect the black cable to the negative terminal of the dead battery, as this could trigger a spark that ignites the gasoline in the engine bay.

Keys that are claimed as new from aftermarket sellers will not work and are almost guaranteed to fail in the crucial moment.
The dealer will charge the highest dollar for only one working key. However, we can reset and re-program the computer's EEPROM in order to prepare it to accept a new key without replacing the whole system. This could save you a significant amount of money. It's cheaper to do this rather than wait until you loose the only key.
