For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller pins and wires to connect.

Once the rows and columns are soldered, it's time to connect them to the key switches. Solder a diode to each key switch pin. This will protect the key switch pins from current and also prevent them from being shorted. A diode allows current to only flow in only one direction. It is equipped with a visible indicator that is black, that indicates which direction current will flow.

Some of the tools offered at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- can aid shop customers or DIY customers in certain instances replace keys in the program and restore lost immobilizer data, Sanabria says.
