After the rows and column are soldered together It is now time to connect the key switches. To do this, you need to place an inverter over each pin on the key switch and then solder it. This will protect the pins of the key switch from current and keep them from being shorted. A diode can only allow the current to flow in a single direction, and it comes with a a black band visual indicator that indicates the direction in which current will flow.

Sanabria says that some of the tools offered in auto parts stores, like the Autel MaxiIM IMM608PRO and IM508, can help customers who are shopping or DIY users to program replacement keys and restore data from the immobilizer. The tools plug into OBD ports and guide the user through each step which makes the process much easier than replacing the car's computer.

Jump starting the battery

Most people keep a set of jumper cables in their trunks for emergencies however, jumping a battery on modern vehicles might not be the best option.
