There isn't a standard method to do it, however, you should plan how to route and solder each column and row. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller wires and pins to connect.

Once the rows and columns are soldered, it's time to connect them to key switches. Solder a diode on each key switch pin. This will shield the pins from current, and prevent them from being cut off. The diode allows current to only flow in only one direction. It comes with a visual indicator that is black, that indicates which direction current will flow.

Sanabria says that some of the tools sold in auto parts stores, including the Autel MaxiIM IM608PRO and IM508 are able to 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 an item in their trunk to start a car in an emergency, however it might not be a good idea for newer cars. These vehicles have many computers and digital devices that communicate with one another. A surge in voltage when a battery is hooked up to another one could damage the components and render your vehicle unable to drive.

Attach the other end to a clean unpainted metal surface under the hood of the damaged car. The engine block is a great option. The black cable should not be connected to the negative terminal of the dead battery. This could trigger a spark, which would ignite the gasoline that is in the engine compartment.
