saab 9-3 key fob programming Key Programming

Saab key programmer cars that were built prior to 1994 feature an immobilizer mechanism that is based on codes for keys. In order to add a second key, it requires a new transponder and special programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.

After the columns and rows are soldered together after which it is time to connect the key switches. To do this, place a diode on each pin of the key switch and solder it. This will shield the pins from current, thus preventing them from being shortened. A diode allows current to only flow in one direction. It features a visual indicator, a black band, that shows which way current will flow.

Some of the tools offered at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- can help shop customers or even DIY users in some cases programme replacement keys and recover lost immobilizer data Sanabria says.
