There is no standard method to accomplish this, however it is important to think about the way you'll route and solder the rows and columns. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins to connect.

After the rows and column are soldered together, it is time to connect the key switches. To do this, place an inverter over each key switch pin and solder it. This will protect the pins of the key switch from current and also prevent them from being shorted. A diode can only allow the flow of current to be in one direction, and it also has a an indicator of black color that shows the direction in which current will flow.

Some of the tools you can find at auto parts stores -- such as the Autel MaxiIM IM608 PRO and IM508 -- can help shop customers or even DIY customers in some cases programme replacement keys and recover lost immobilizer information, Sanabria says.

Jump-starting the battery

The majority of people have a set of jumper cables in their trunk in case of emergency, but jumping a battery on newer automobiles might not be the best choice. These vehicles are equipped with many computers and digital devices which communicate with each other. A surge in voltage when a battery is hooked up to another battery could fry these components, rendering your vehicle unable to drive.

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 in the engine compartment.
