Saab cars manufactured since 1994 feature an immobilizer system that is based on a set of keys. Adding an extra key requires an entirely new transponder and programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.
It can be costly. It is recommended to always have a spare set of keys at hand.
Transponder key
The transponder key is a piece of hardware with an electronic chip that transmits a signal to the car when it is placed in the ignition. The car then examines the signal to see whether it matches the one in the key. If the signals are identical the car will then unlock itself and start. This is a great way to guard your car against theft.
Transponder keys could be an increasingly popular feature for cars, but they are not as secure as traditional metal keys. While the metal parts of a traditional key may be cut and copied however, a transponder is secured by an electronic chip. The chip contains a unique code that is programmed into a car's computer order to identify it.
The car will recognize the Saab keyfob and allow it to be turned on. But, it's only able to do this if the key fob is equipped with a chip that is not modified that has been programmed to match. Otherwise, the car will reject the key and won't start.

The next step is connecting the wires for columns and rows to your microcontroller. This is the most laborious component of the project and it will require a lot of soldering. There is no standardized way to accomplish this, but it is essential to determine how you will route and solder the rows and columns. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller pins and wires to connect.
After the rows and column are joined after which it is time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins of the key switch from current and prevent them from being shorted. A diode only allows the current to flow in a single direction, and it comes with a an indicator of black color that shows the direction in which current will flow.
Some of the tools available at auto parts stores -- such as the Autel MaxiIM IM608 PRO and IM508 -- could help customers in the shop, or even DIY customers in some cases replace keys in the program and restore the lost immobilizer's data, Sanabria says. The tools plug into the OBD port and guide the customer through the process, making it easier than replacing the computer inside the vehicle.
Jump-starting the battery
Most people keep a set of jumper cables in their trunks for emergencies, but jumping a battery in newer cars might not be the best choice. These vehicles are equipped with numerous computers and digital devices which communicate with one another. A voltage spike when a battery is hooked up to another battery could fry these components and render your vehicle unable to drive.

Attach the other end to a clean, unpainted metal surface underneath the hood of the affected vehicle. The engine block is a great option. The black cable should not be connected to the negative terminal of the dead battery. This could cause a spark, which would ignite the gasoline in the engine compartment.

In the event of theft, or any other calamity it is advisable to have an extra key. Even it's "new" it will not work.
The dealer will charge the highest dollars if you only have one working key. We can, however, reset and reprogram the computer's EEPROM in order to prepare it to accept an alternative key without replacing the whole system. This could save you a lot of money. It's more affordable instead of waiting until you lose the sole key.
