Saab Key Programming

If both signals match, the car will unlock itself and start. This is a great way to prevent auto theft and keep your vehicle safe from thieves.

Transponder keys could be a popular addition to cars, but they're not as safe as traditional metal keys. While the metal component of a traditional key can be cut and copied however, a transponder is secured by an electronic chip.

It's not a common way to go about it, however, you should determine how to route and connect each column and row. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins that you need to connect.

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 shield the pins that are used for key switches from current and stop them from being shorted. The diode allows current to only flow in only one direction. It features a visual indicator, a black band, that indicates the direction in which current will flow.

Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to a clean, unpainted metal surface under the disabled car's hood. The engine block would be a good option. Don't connect the black cable to the negative terminal of the dead battery, as this could cause a spark that ignites the gasoline in the engine bay.

After the cables have been connected, you can start the car and let it run for approximately five minutes. Then disconnect the cables in reverse.
