Transponder keys may be a popular addition to cars, but they are not as secure as traditional keys made of metal. The metal component of a traditional key can be easily copied and cut, but transponders have an electronic chip that protects it. The chip has an unique code that is encoded into the car's system to identify it.
When a Saab key fob is used, the car recognizes it and allows it to turn on. The car can only recognize the key fob if it has an unmodified chip and has been programmed to match. In the absence of that, the car will reject the key and won't start.

There's no standard way to go about it, but you need to consider how you will route and connect each column and row. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins to connect.
After the columns and rows are soldered, it's time to connect them to key switches. To do this, place a diode on each key switch pin and solder it. This will shield the pins that are used for key switches from current and stop them from being shorted. A diode permits current to only flow in only one direction. It features a visual indicator with a black band that shows the direction in which the current will flow.
