Saab Key Programming
saab key programming cars built from 1994 have an immobilizer system that is based on key codes. To add an additional key, you need a new transponder and special programming. This is usually done at the dealer using a Tech2 diagnostic tool.

Transponder key
The transponder is a type of key that is equipped with an electronic chip. The chip transmits a signal when the key is put into the ignition.

Transponder keys could be an increasingly popular feature for automobiles, but they are not as safe as traditional keys made of metal. The metal portion of a traditional key is easily cut and copied, however the transponder is protected by an electronic chip that guards it.

Jump starting the battery
A majority of people keep a set in their trunk to jump start a vehicle in an emergency, but this might not be the best option for vehicles with newer technology. These cars have a variety of electronic devices and computers that communicate with one another. A surge of voltage when a battery is connected to another battery could damage the components making your car inoperable.
Connect the cables to the vehicle working. Let it run for two minutes. Attach the red clip to the positive terminal on the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clean and unpainted metal surface under the hood of the disabled vehicle. The engine block is an excellent alternative. Don't connect the black cable to the negative terminal of the dead battery as it could spark a spark that ignites the gasoline in the engine bay.
Once the cables are connected, you need to start the car and let it run for about five minutes. Then disconnect the cables in reverse. Remember that the battery on your Saab 9-3 is charged while you drive, so it will take a while for the battery to go down.

Replacement case
Many saab 93 key owners only have one key for their car and if they lose that key, it will cost them. It's expensive to add keys and will require replacing the CIM or TWICE for older models.

Keys that are claimed as new from a second-hand store will not perform and are almost certain to fail at the critical moment.
Most locksmiths cannot help you with a single working key and the dealer will charge you high prices to replace the computer in your vehicle to create a replacement. We can, however, reset and re-program the computer's EEPROM to accept a new key without replacing the whole system. This could save you a significant amount of money. It's less expensive rather than wait until you loose the only key.
