Saab Key Programming
saab 93 key fob cars manufactured since 1994 use an immobilizer that relies on key codes. A new transponder is required for addition of an additional key, as well as special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.
It can be costly. This is why you should always keep a spare key in your possession.
Transponder key
The transponder is a piece of key with an electronic chip. This chip sends a signal when the key is placed in the ignition. The car will check to see whether the signal matches with the one on the key. If both signals match the car will be able to unlock itself and begin. This is a great way to guard your car against theft.
Transponder keys could be an increasingly popular feature for cars, but they are not as secure as traditional metal keys. While the metal parts of a traditional key may be cut and copied however, a transponder is secured by an electronic chip. The chip is a unique code that is inserted into a car’s computer order to identify it.
When a Saab key fob is used the car recognizes it and allows it to turn on. The car can only recognize the key fob when it has a chip that is unmodified and has been programmed to match. Otherwise, the car will reject the key and won’t 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 great amount of soldering. There is no standard method to accomplish this, however it is essential to determine the way you’ll route and solder the columns and rows. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller wires and pins to connect.
Once the rows and columns are soldered, it’s the time to connect them to the key switches. To do this, put an inverter over each pin of the key switch and solder it. This will shield the pins of the key switch from current and also prevent them from being shorted. A diode can only allow the flow of current to be in one direction, and it has a black band visual indicator that shows the direction in which current will flow.
Sanabria states that a number of the tools offered in auto parts stores, like the Autel MaxiIM IMM608PRO and IM508, can help customers who are shopping or DIY customers to program replacement keys and restore immobilizer data. The tools connect to the OBD port and automatically guide the customer through the procedure, making it much easier than replacing the computer in the vehicle.
Jump-starting the battery
A lot of people keep the set in their trunk to start a car in an emergency, however it might not be a good idea for vehicles that are newer. These vehicles are equipped with numerous digital and computer systems that communicate with one another. A voltage surge when a battery is connected to another can fry the components making your car unusable.
Connect the cables to the vehicle that is operating. Let it run for two minutes. Attach the red clip to the positive terminal of the good battery (it will have “POS” or “+” on it). Attach the other end of the black cable to a clean, unpainted metal surface underneath the disabled 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 cause a spark, which would ignite the gasoline in the engine compartment.
Once the cables are connected, you can start the vehicle you are not using and allow it to run for around five minutes before you disconnect the cables in reverse order. The battery in the Saab 9-3 will charge while you drive. It will take some time for it to drop back down. It is recommended to purchase another key fob as soon as you can. Replacing the original one that works requires the installation and programming of a brand new computer chip.
Replacement case
Many Saab owners have only one key for their car and if they lose it, the cost will be. The reason for this is that it’s not inexpensive to buy a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. In the event of theft, or any other calamity, it is best to have an extra key. Don’t purchase a used key even if it’s “new.” Keys that are claimed-new from aftermarket sellers will not be effective and are almost guaranteed to fail at the critical moment.
