saab keys replacement cars built since about 1994 come with an immobilizer system based on coded keys. In order to add a second key, it requires the purchase of a new transponder as well as 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 at hand.
Transponder key
The transponder key comes with an electronic chip that sends a signal to car when it is placed in the ignition. The car will check to see whether the signal matches the one on the key. If the signals match it will open itself and begin. This is an excellent way to protect your vehicle from theft.
Transponder keys are an increasingly popular feature in vehicles, but it is important to know that they are not as secure as classic keys made of metal. The metal portion of a traditional key is easily cut and copied, whereas the transponder is protected by an electronic chip that guards it. This chip has an individual code that is programmed into the car's computer to identify it.
When a saab key programmer key fob is used, the car recognizes it and allows it to turn on. However, it will only do this if the fob is unmodified and has a chip that has been programmed to match it. The car won't start in the event that the key has not been programmed to match.

The next step is to wire the column and row wires to the microcontroller. This is the most difficult part of the project and will require a good deal of soldering. There isn't a standard way to accomplish this, but it is essential to determine the route you'll take and solder the rows and columns. There are 22 microcontroller pins and wires to connect for this keyboard. It includes 5 rows and 17 column.
After the columns and rows are joined then it's time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins from current, and prevent them from getting shorted. A diode lets current only flow in only one direction. It has a visual indicator, 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, including the Autel MaxiIM IM608PRO and the IM508 are able to assist customers shopping or DIY users to program replacement keys and restore data from the immobilizer. 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 majority of people keep an item in their trunks to jump start a car in case of emergency, however it might not be the best idea for cars with more modern technology. These cars have a variety of digital and computer systems that communicate with each other. A voltage surge when batteries are connected to another battery could damage the components making your car inoperable.
Start the working vehicle and let it run for about two minutes before connecting the cables to the battery that is not working. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to a clean, unpainted metal surface under the disabled car's hood. The engine block would be a good choice. The black cable is not to be connected to the negative terminal of the dead battery. This could result in sparks, which could ignite gasoline in the engine compartment.
Once the cables are connected, you can start the vehicle you are not using and let it run for about five minutes before disconnecting them in reverse order. Be aware that the battery in your saab 9-3 key programming 9-3 is charged when you drive, so it can take a while to get the battery back to normal. It's a good idea to purchase a spare fob as soon as you can, since replacing the one that works requires the installation of a brand new computer module and special programming to convince the system that your lost keys aren't attempting to steal the car.
Replacement Case
Saab owners typically only have one car key, and if that is lost, they will be charged. The reason is that it's not cheap to purchase a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. It's recommended to have a spare key in the event of theft or other disaster, and the best way is to purchase a second key as early as you can. Even when the key is "new" it won't work.
The dealer will charge you the most expensive dollars if you only have one working key. We can, however, reset and reprogram the computer's EEPROM to accept the new key, without replacing the whole system. This can save you a great deal of money. It's also much less expensive than waiting until you lose your only key.
