saab key fob replacement Key Programming

Saab cars manufactured since 1994 utilize an immobilizer system that relies on keys that are coded. A new transponder is required for addition of an extra key, as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.

This can be expensive. It is always advisable to keep a spare set of keys available.

Transponder key

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

Transponder keys could be a popular addition to automobiles, but they are not as secure as traditional metal keys. While the metal part of a traditional key may be cut and copied the transponder is protected by an electronic chip. The chip is equipped with a unique code that is programmed into the car's computers to identify it.

When a Saab key fob is used the car recognizes it and allows it to turn on. However, it can only do so if the key fob has a non-modified chip that has been programmed to match it. If not, the car will reject the key and refuse to start.

It has 5 rows and 17 column.

After the columns and rows are soldered, it's time to connect them to key switches. To do this you must place a diode over each pin of the key switch and solder it. This will shield the key switch pins from current and also prevent them from being shorted. The diode allows current to only flow in only one direction. It features a visual indicator of a black line that shows the direction in which the current will flow.

Sanabria states that some of the tools available in auto parts stores, such as the Autel MaxiIM IM608PRO and the IM508 can assist shoppers or DIY customers to program replacement keys and restore immobilizer information.
