Saab cars that were built prior to 1994 have an immobilizer feature that is based on codes for keys. A new transponder is required for the addition of an extra key, as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.
This can be expensive. It is recommended to always have an extra set of keys on hand.
Transponder key
The transponder key is a key with an electronic chip that sends a signal to the car when it is placed in the ignition. The car then analyzes the signal to see whether it matches the one on the key.

The car will recognize the saab key replacement bristol keyfob, and allow it to turn on. But, it's only able to do this if the fob is unmodified and has a chip that has been programmed to match. The car won't start if the key is not programmed to match.

There is no standardized way to accomplish this, but it is crucial to plan the way you'll route and solder the columns and rows. There are 22 microcontroller wires as well as pins to connect for this keyboard. It has 5 rows and 17 column.
After the rows and column are joined It is now time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins from current, thus preventing them from being shorted. A diode only allows current to flow in one direction, and has a the black band as a visual indicator that indicates which way the current will flow.
Some of the tools available at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 – could help shop customers or even DIY customers in some cases program replacement keys and restore lost immobilizer data, Sanabria says. The tools plug into OBD ports and guide the user through each step making the process simpler than replacing the vehicle's computer.
Jump-starting the battery
Most people keep a set of jumper cables in their trunks for emergency situations, but jumping a battery on modern vehicles may not be the best idea. These vehicles have many electronic devices and computers that communicate with each other. A voltage spike when the battery is connected to another can fry the components and render your vehicle unusable.

Attach the red clip on the positive terminal of the good battery. (It will say “POS” or “+”.) Attach the other end of the black cable to a clean, unpainted metal surface beneath the damaged car's hood–the engine block is a good option. The black cable is not to be connected to the negative terminal of the dead battery. This could result in sparks, which would ignite gasoline in the engine compartment.
Once the cables are connected, you can begin the car and allow it to run for around five minutes. Then, disconnect them in reverse.

You should purchase another key fob as soon as you can. Replacing the only one that works requires the installation and programming of a new computer chip.
Replacement Case
