Saab Key Programming

saab replacement keys cars built since 1994 utilize an immobilizer system that relies on a set of keys. In order to add a second key, it requires the purchase of a new transponder as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

There is no standard method to accomplish this, however it's important to plan out the routes you'll use to solder the rows and columns. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller pins and wires to connect.

After the rows and column are joined It is now time to connect the key switches. To do this, put a diode on each pin of the key switch and then solder it. This will shield the pins from current and prevent them from getting shorted. A diode allows current to only flow in one direction. It has a visual indicator, a black band, that shows which way current will flow.

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