There's no standard way to go about it, but you need to consider how you will connect and solder each column and row. There are 22 microcontroller wires as well as pins to connect for this keyboard. It has five rows and 17 column.

Once the rows and columns are soldered, it's the time to connect them to the key switches. To do this, place a diode across each pin on the key switch and then solder it. This will shield the pins from current, and prevent them from being shorted. A diode only allows the current to flow in a single direction, and has a a black band visual indicator that indicates which way the current will flow.

Some of the tools offered at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- may help shop customers or even DIY customers in some cases programme replacement keys and recover lost immobilizer information, Sanabria says.
