Transponder keys are a popular feature in vehicles, but it is important to know that they aren't as secure as traditional metal keys. The metal part of the traditional keys can be easily cut or copied, while transponders are protected by an electronic chip that protects it. This chip contains a unique code that is programmed into the car's computers to identify it.

For this keyboard, there are 5 rows and 17 columns, which means there will be 22 microcontroller wires and pins that you need to connect.
Once the rows and columns are soldered, it's the time to connect them to the key switches. To do this you must place a diode on each pin of the key switch and then solder it. This will protect the pins from current, thus preventing them from being shorted. A diode allows current to only flow in only one direction. It comes with a visual indicator of a black line that shows the direction in which the current will flow.
