Saab Key Programming

Saab cars made since 1994 have an immobilizer system that is based on codes for keys. The addition of a key requires the purchase of a new transponder as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.

This can be expensive. You should always keep a spare set of keys on hand.

Transponder key

The transponder key is a piece of hardware equipped with an electronic chip. It sends a signal to car when it is inserted into the ignition. The car checks to see whether the signal matches the one on the key. If the signals are in sync the car will then open and start. This is a great method to guard your car against theft.

This is because, if it's lost, the car will need a new CIM and the locking cylinders replaced. This could be expensive, especially if you are buying a used car.

The next step is to connect the wires for columns and row to your microcontroller. This is the most difficult part of the project and will require a great amount of soldering. There is no standardized way to accomplish this, however it's important to plan out how you will route and solder the rows and columns. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller wires and pins to connect.

After the columns and rows are soldered together, it is time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins from current and prevent them from being shortened. The diode will only allow the current to flow in a single direction, and it also has a an indicator in black that shows the direction in which current will flow.

A few of the tools that are available at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- can help customers in the shop, or even DIY customers in certain cases programme replacement keys and recover lost immobilizer information, Sanabria says. The tools plug into the OBD port and guide the customer through the process, making it easier than replacing the computer in the vehicle.

Jump-starting the battery

The majority of people have a set of jumper cables in their trunks to use in an emergency however, jumping a battery on modern automobiles might not be the best idea.

The black cable should not be connected to the negative terminal of the dead battery. This could cause sparks that could ignite gasoline in the engine compartment.

Once the cables are connected, start the disabled vehicle and let it run for approximately five minutes before disconnecting them in reverse order. Keep in mind that the battery on the saab replacement key 9-3 will be charged during your drive, which means it could take a while to get the battery back to its original level. You should consider purchasing another key fob as soon as you can. Replacing the only one that works requires the installation and programming of a new computer chip.
