Saab Key Programming

Saab cars that were built prior to 1994 have an immobilizer feature based on coded keys. A new transponder is required for addition of an extra key, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

The problem is that this could be extremely expensive. This is why it is important to always have a spare key at hand.

Transponder key

The transponder is a type of key equipped with an electronic chip. The chip sends a signal when the key is put in the ignition.

While the metal parts of a traditional key can be cut and copied however, a transponder is secured by an electronic chip. The chip is equipped with a unique code embedded into the car's computer to identify it.

When a saab car key replacement key fob is used, the car recognizes it and allows it to turn on. However, it is only able to do this if your key fob is unmodified and has a chip that has been programmed to match. If not, the car will reject the key and won't start.

There's no standard way to do it, however, you should plan how to program saab 9-3 key fob to connect and solder each column and row. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller pins and wires to connect.

After the columns and rows are soldered, it's the time to connect them to key switches. To do this, put an inverter over each pin of the key switch and solder it. This will protect the pins from current, and prevent them from getting shorted. A diode only allows the flow of current to be in one direction, and it also has a the black band as a visual indicator that indicates the direction current will flow.

Sanabria says that a few of the tools sold in auto parts stores, including the Autel MaxiIM IM608PRO and IM508 will assist customers who are shopping or DIY users to program replacement keys and restore the immobilizer's data. The tools connect to the OBD port and automatically guide the user through the process, making it easier than replacing the computer in the vehicle.

Jumpstarting the battery
