Saab cars that were built prior to 1994 have an immobilizer system that is based on codes for keys. A new transponder is required to allow the addition of an extra key, and special programming. This is usually done at the dealer using a special Tech2 diagnostic tool.

The problem is that it can be very expensive. This is why it is important to always keep a spare key in your possession.

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 placed in the ignition. The car checks to see if the signal matches the one on the key. If the signals are the same it will open itself and start. This is a great method to avoid car theft and keep your vehicle safe from thieves.

Transponder keys are a favored feature in automobiles, however you should be aware they're not as secure as classic metal keys. While the metal portion of a traditional key may be cut and copied, a transponder is protected by an electronic chip. This chip contains an unique code that's programmed into a car's computer in order to identify it.

The car will recognize the Saab keyfob and permit it to turn on. However, it can only do this if the key fob has an unmodified chip that has been programmed to match it. The car won't start when the key isn't programmed to match.

It's crucial to ensure that you have an extra key for your Saab. This is especially true when you live in a rural area where there are numerous car thieves.

Wired key

Saab cars usually come with two keys when new. If you have only one, it's best to acquire an additional key fob as soon as is possible since if you lose it, your car will require the replacement of a CIM unit and the locking cylinders have to be replaced. This can be costly particularly if you are purchasing a used vehicle.

The next step is to wire the wires for the column and row to the microcontroller. This is the toughest part of the project and will require a lot of soldering.

There are 22 microcontroller wires and pins that you can connect to this keyboard. It has five rows and 17 columns.

Once the rows and columns are soldered, it's the time to connect them to the key switches. To do this, you need to place an inverter over each pin on the key switch and solder it. This will protect the pins on the key switch from current and keep them from being shorted. A diode allows current to only flow in one direction. It comes with a visual indicator, a black band, that indicates the direction in which current will flow.

Sanabria states that a number of the tools offered in auto parts stores, such as the Autel MaxiIM IM608PRO and IM508 can assist customers who are shopping or DIY customers to program replacement keys and restore immobilizer information. The tools plug into the OBD port and automatically guide the user through the procedure, making it much easier than replacing the computer in the vehicle.

Jump-starting the battery

A lot of people keep a set of jumper cables in their trunks to use in an emergency however, jumping a battery in newer automobiles might not be the best choice. These cars have a variety of digital and electronic devices that communicate with each other. A surge in voltage when batteries are connected to another one could cause damage to the parts making your car unusable.

Start the working vehicle and allow it to run for around two minutes before connecting the cables to the battery that is not working. 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 of the black cable to a clean, unpainted metal surface underneath the car's hood. The engine block would be a good option. The black cable should not be connected to the negative terminal of the dead battery. This could trigger sparks that could ignite gasoline in the engine compartment.

Once the cables are connected, you can start the car and let it run for about five minutes. Then, disconnect the cables in reverse. Keep in mind that the battery on the Saab 9-3 gets recharged while you drive, so it could take a while for the battery to go back down again. It is a good idea to buy a spare key fob as soon as you can, because replacing the sole working one requires the installation of a new computer module and a special program to convince the system that your lost keys aren't in the process of trying to steal the car.

Saab owners often only have one car key, and if it is lost, they will be charged. The reason is that it's not cheap to buy a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming.
