Saab Key Programming

Saab cars built since 1994 feature an immobilizer that relies on key codes. A new transponder is required for addition of an extra key, and special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

The issue is that it can be very costly. Always keep an extra set of keys on hand.

Transponder key

The transponder key is a key with an electronic chip that transmits a signal to the car when it is inserted into the ignition. The car will check to see whether the signal matches the one on the key. If the signals match it will open and start. This is an excellent way to guard your car against theft.

Transponder keys are a popular feature in automobiles, but you should be aware they're not as secure as traditional metal keys.

The next step is to connect the wires for columns and row to your microcontroller. This is the most challenging part of the project and requires a significant deal of soldering. There isn't a standard method to do it, but you need to plan how to connect and solder each column and row. There are 22 microcontroller wires and pins that you can connect for this keyboard. It has 5 rows and 17 column.

After the columns and rows are soldered together, it is time to connect the key switches. To do this you must place a diode on each key switch pin and then solder it. This will shield the pins from current, preventing them from being shorted. A diode permits current to only flow in one direction. It comes with a visual indicator that is black, that indicates the direction in which current will flow.

Sanabria says that some of the tools sold in auto parts stores, like the Autel MaxiIM IM608PRO and IM508 are able to assist shoppers or DIY users to program replacement keys and restore data from the immobilizer. The tools connect to OBD ports and guide the customer through each step making the process simpler than replacing the vehicle's computer.

Jump starting the battery

Most people keep a few sets of jumper cables in their trunk for emergency situations, but jumping a battery for newer cars might not be the best idea. These vehicles are equipped with digital and computer systems that communicate with each other. A voltage surge while a battery is hooked up to another can fry these components and render your car unable to drive.

Start the vehicle that is working and let it run for about two minutes before connecting the cables to the disabled one. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end to a clear, unpainted metal surface underneath the hood of your disabled car. The engine block is an excellent choice. Don't connect the black cable to the negative terminal on the dead battery, as it could ignite an ignition spark that ignites the gasoline in the engine bay.

Once the cables are connected, you need to start the car and allow it to run for around five minutes. Then disconnect them in reverse. The battery in the Saab 9-3 will charge while you drive. It takes a while for it to drop back down. It is a good idea to invest in a spare key fob as soon as you can, because replacing the sole working one requires the installation of a brand 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.
