Saab Key Programmingsaab 9-3 key replacement cars made since 1994 come with an immobilizer system made up of coded keys. In order to add a second key, it requires a new transponder, as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.
The problem is that it can be extremely expensive. Always keep 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 inserted into ignition. The car then checks the signal to determine whether it is identical to the one on the key. If the signals match the car will then unlock and start. This is a great method to protect your vehicle from theft.
Transponder keys are an increasingly popular feature for cars, but they're not as secure as traditional metal keys. The metal component of the traditional key can be easily copied and cut, but transponders have an electronic chip which protects it. This chip contains an unique code that's 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 fob is equipped with a chip that is not modified that has been programmed to match. The car will not start when the key isn't programmed to match.

The next step is to wire the wires of the column and row to the microcontroller. This is the most difficult part of the project, and it will require a lot of soldering. There is no standard method to do this, but it is essential to determine the route you'll take and solder the rows and columns. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins that you need to connect.
After the columns and rows are soldered, it's time to connect them to the key switches. To do this you must place a diode on each pin on the key switch and solder it. This will protect the pins that are used for key switches from current and keep them from being shorted. A diode permits current to only flow in only one direction. It features a visual indicator with a black band that shows which way current will flow.
Sanabria states that some of the tools sold in auto parts stores, including the Autel MaxiIM IM608PRO and IM508 are able to assist customers who are shopping or DIY customers to program replacement keys and restore immobilizer data. The tools plug into the OBD port and guide the user through the procedure, making it much easier than replacing the computer inside the vehicle.
Jump-starting the battery
A lot of people keep the set in their trunk to start a vehicle in an emergency, however it might not be the best idea for cars with more modern technology.

Attach the other end of the black cable to a clean, unpainted metal surface beneath the damaged car's hood. The engine block would be an excellent choice. The black cable should not be connected to the negative terminal of the dead battery. This could result in sparks that could ignite the gasoline inside the engine compartment.
