There is no standard method to do this, but it is important to think about how you will route and solder the columns and rows. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller pins and wires to connect.
After the columns and rows are soldered, it's time to connect them to the key switches. Solder a diode on each key switch pin. This will shield the pins that are used for key switches from current and prevent them from being shorted. A diode allows current to only flow in only one direction. It is equipped with a visible indicator of a black line that indicates which direction current will flow.
Some of the tools offered at auto parts stores -- such as the Autel MaxiIM IM608 PRO and IM508 -- can help customers in the shop, or even DIY customers in some cases replace keys in the program and restore lost immobilizer information, Sanabria says.
