After the columns and rows are joined after which 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 pins that are used for key switches from current and also prevent them from being shorted. A diode allows the flow of current to be in one direction, and has a the black band as a visual indicator that indicates the direction in which current will flow.

Sanabria states that a number of the tools that are sold in auto parts stores, including the Autel MaxiIM IM608PRO or IM508 will assist customers who are shopping or DIY customers to program replacement keys and restore the immobilizer's data.

Jump-starting the battery

Most people keep a few sets of jumper cables in their trunk in case of emergency, but jumping a battery on newer cars might not be the best idea.
