Saab Key Programming

Saab cars manufactured since 1994 come with an immobilizer system built on coded keys. A new transponder is required for the inclusion of an additional 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. Always keep a spare set of keys in your possession.

Transponder key

The transponder is a piece of key that is equipped with an electronic chip. The chip sends a signal when the key is put into the ignition.

This is a great method to stop auto theft and keep your car safe from thieves.

Transponder keys are a popular feature in vehicles, but it is important to know that they're not as secure as classic keys made of metal.

The chip has a unique code that is inserted into a car's computers in order to identify it.

The car will recognize the Saab keyfob and permit it to be turned on. The car will only recognize the key fob when it has a chip that is unmodified and programmed to match. Otherwise, the car would reject the key and refuse to start.

There's no standard way to do it, however, you should plan how to route and solder each column and row. There are 22 microcontroller wires and pins to connect for this keyboard. It has 5 rows and 17 column.

After the rows and column 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, preventing them from being cut off. A diode can only allow the current to flow in a single direction, and it comes with 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, such as the Autel MaxiIM IM608PRO or IM508 can assist shoppers or DIY customers to program replacement key for saab 93 keys and restore immobilizer information.
