Saab Key Programming
Saab cars manufactured since 1994 have an immobilizer feature built on coded keys. In order to add a second key, it requires a new transponder, as well as special programming. This is usually done by the dealer, using a specially-designed Tech2 diagnostic tool.

Transponder key
The transponder can be described as a key with an electronic chip. The chip sends a signal when the key is placed in the ignition. The car then checks to see whether the signal matches with the one on the key. If the signals match it will open itself and begin. This is a great way to stop car theft and keep your car secure from thieves.

The car will recognize the Saab keyfob and permit it to be turned on. However, it can only do this if the key fob is unmodified and has a chip that has been programmed to match. The car won't start in the event that the key has not been programmed to match.

There isn't a standard method to go about it, but you must consider how you will route and connect each column and row. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller wires and pins that you need to connect.
After the columns and rows are soldered together, it is time to connect the key switches. Solder a diode to each key switch pin. This will protect the key switch pins from current and also prevent them from being shorted. A diode lets current only flow in one direction. It is equipped with a visible indicator with a black band that indicates the direction in which current will flow.
Some of the tools offered at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- may help shop customers or even DIY customers in certain cases programme replacement keys and recover lost immobilizer data, Sanabria says.
