Once the rows and columns 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 from current, preventing them from being shorted. A diode allows current to only flow in only one direction. It comes with a visual indicator, a black band, that shows which way current will flow.

Some of the tools offered at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- may help customers in the shop, or even DIY customers in some cases program replacement keys and restore lost immobilizer information, Sanabria says.
