Saab Key Programming

Saab cars that were built prior to 1994 have an immobilizer feature made up of coded keys. The addition of a key requires an entirely new transponder and programming. This is usually done by the dealer, using a specially-designed Tech2 diagnostic tool.

The issue is that this can be quite costly. This is why it is important to always have a spare key at hand.

Transponder key

The transponder is a key with an electronic chip. The chip sends a signal when the key is inserted into the ignition. The car checks to see if the signal matches the one on the key. If the signals match it will open itself and begin. This is an excellent way to guard your car against theft.

Transponder keys are a favored feature in automobiles, but you must be aware that they're not as secure as traditional keys made of metal. While the metal component of a conventional key can be cut and copied, a transponder is protected by an electronic chip. This chip contains a unique code that is encoded into the car's system to identify it.

When a saab 93 key key fob is used the car recognizes it and allows it to turn on. But, it's only able to do this if the key fob has a non-modified chip that has been programmed to match it. In the absence of that, the car will refuse to accept the key and will not start.

The next step is to wire the column and row wires to the microcontroller. This is the most laborious component of the project and will require a lot of soldering. There's no standard way to go about it, but you need to consider how to open a saab 93 without a key (Full Content) you will route and connect each column and row. There are 22 microcontroller wires and pins that you can connect to this keyboard. It has 5 rows and 17 column.

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

Sanabria says that some of the tools sold in auto parts stores, including the Autel MaxiIM IM608PRO or IM508 are able to assist customers who are shopping or DIY users to program replacement keys and restore immobilizer information. The tools plug into OBD ports and guide the user through each step which makes the process much easier than replacing the car's computer.

Jump-starting the battery

Most people keep a few sets of jumper cables in their trunks to use in an emergency however, jumping a battery on newer cars might not be the best option.

Attach the other end to a clean unpainted metal surface underneath the hood of the damaged car. The engine block is an excellent choice. Don't connect the black cable to the negative terminal of the dead battery, as this could trigger an ignition that ignites the gasoline in the engine bay.

After the cables have been connected, you can start the car and allow it to run for around five minutes. Then, disconnect the cables in reverse. Be aware that the battery in your Saab 9-3 is charged when you drive, and it may take some time for the battery to come back to its original level.
