There's no standard way to accomplish this, however it's important to plan out the routes you'll use to solder the columns and rows. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins that you need to connect.

After the rows and column are soldered together, it is time to connect the key switches. To do this you must place a diode on each pin on the key switch and then solder it. This will protect the pins from current, preventing them from being shortened. A diode permits current to only flow in only one direction. It is equipped with a visible indicator, a black band, that indicates which direction current will flow.

Sanabria states that a number of the tools offered in auto parts stores, including the Autel MaxiIM IM608PRO and the IM508 are able to assist customers shopping or DIY users to program replacement keys and restore immobilizer information.
