It has 5 rows and 17 columns.

After the columns and rows are soldered together, it is time to connect the key switches. To do this, you need to place a diode over each key switch pin and solder it. This will protect the key switch pins from current and prevent them from being shorted. The diode allows current to only flow in one direction. It is equipped with a visible indicator, a black band, that shows the direction in which the current will flow.

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