Once the rows and columns are soldered, it's time to connect them to key switches. To do this, place a diode across each pin of the key switch and solder it. This will shield the key switch pins from current and prevent them from being shorted. A diode lets current only flow in one direction. It comes with a visual indicator of a black line that shows which way current will flow.
Sanabria says that some of the tools sold in auto parts stores, such as the Autel MaxiIM IM608PRO and IM508 will assist customers shopping or DIY users to program replacement keys and restore immobilizer information.

Jump-starting the battery
The majority of people have a set of jumper cables in their trunk to use in an emergency, but jumping a battery for newer cars might not be the best choice.
