Saab Key Programming

Transponder key

The transponder can be described as a key equipped with an electronic chip. This chip sends a signal when the key is put into the ignition.

There are 22 microcontroller pins and wires to connect to this keyboard. It has five rows and 17 column.

Once the rows and columns are soldered, it's time to connect them to key switches. Solder a diode to each key switch pin. This will protect the pins on the key switch from current and also prevent them from being shorted. The diode allows current to only flow in one direction. It comes with a visual indicator of a black line that shows the direction in which the current will flow.

Sanabria says that a few of the tools available in auto parts stores, including the Autel MaxiIM IM608PRO and the IM508 will assist shoppers or DIY customers to program replacement keys and restore data from the immobilizer.
