Saab cars built since about 1994 have an immobilizer feature built on coded keys. Adding an extra key requires a new transponder and special programming. This is usually done by the dealer using a Tech2 diagnostic tool.
It can be costly. Always keep an extra set of keys available.
Transponder key
The transponder is a piece of key that is equipped with an electronic chip. This chip sends a signal when the key is inserted in the ignition. The car then checks the signal to see if it matches that of the key. If the signals match, the car will open and start. This is a great way to deter car theft and keep your car secure from thieves.
Transponder keys are a common feature in vehicles, but you should be aware they are not as secure as classic keys made of metal. While the metal component of a traditional key can be cut and copied the transponder is protected by an electronic chip. The chip contains a unique code that is inserted into a car's computer order to identify it.
When a saab key programmer key fob is used the car recognizes it and allows it to turn on. But, it's only able to do this if your key fob has a non-modified chip that has been programmed to match it. If not, the car will reject the key and refuse to start.

The next step is to connect the wires for columns and rows to your microcontroller. This is the most difficult part of the project and will require a good deal of soldering. There is no standard method to do this, but it is crucial to plan how you will route and solder the rows and columns. There are 22 microcontroller pins and wires to connect for this keyboard. It has five rows and 17 columns.
After the rows and column are joined then it's time to connect the key switches. Solder a diode to each key switch pin. This will shield the pins from current, preventing them from being cut off. The diode allows current to only flow in one direction. It has a visual indicator of a black line that indicates the direction in which current will flow.
Some of the tools you can find at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- could assist customers at the shop or DIY customers in some cases replace keys in the program and restore the lost immobilizer's data, Sanabria says. The tools connect to OBD ports and guide the customer through each step making the process simpler than replacing the car's computer.
Jump-starting the battery
Most people keep a set of jumper cables in their trunks for emergencies however, jumping a battery in newer cars might not be the most efficient option. These vehicles are equipped with many digital and computers that communicate with each other. A surge in voltage while the battery is connected to another one could damage these components and leave your vehicle unable to drive.
Start the vehicle that is working and let it run for about two minutes before you connect the cables to the one that is disabled. Attach the red clip to the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end to a clean unpainted metal surface underneath the hood of your disabled car. The engine block is an excellent choice. Don't connect the black cable to the negative terminal on the dead battery, since this could cause a spark that ignites the gasoline in the engine bay.
Once the cables are connected, you can start the vehicle and let it run about five minutes. Then disconnect them in reverse. The battery in your saab 9-3 key 9-3 is recharged while you drive.

In the event of theft, or other catastrophe it is recommended to have an extra key. Even if the key is "new", it will not function.
The dealer will charge you the highest dollar if you only have one working key. We can, however, reset and re-program your computer's EEPROM to prepare it to accept a new key without replacing the entire system. This can save you a lot of money. It's less expensive rather than wait until you lose your only key.
