Transponder keys could be a popular addition to cars, but they are not as safe as traditional metal keys. The metal part of the traditional key can be easily cut and copied, whereas transponders have an electronic chip that protects it. This chip contains an unique code which is programmed into a car's computers in order to identify it.

The car will recognize the Saab keyfob, and allow it to turn on. The car will only recognize the key fob when it has an unmodified chip and programmed to match. The car won't start in the event that the key is not programmed to match.

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

After the rows and column are soldered together It is now time to connect the key switches. To do this, put a diode on each pin of the key switch and solder it. This will protect the pins from current, preventing them from getting shorted. A diode allows current to only flow in one direction. It is equipped with a visible indicator, a black band, that indicates which direction current will flow.

Sanabria says that some of the tools sold in auto parts stores, like the Autel MaxiIM IM608PRO and the IM508 are able to assist customers shopping or DIY users to program replacement keys and restore immobilizer information.
