The next step is connecting the wires for columns and rows to your microcontroller. This is the most tedious part of the project, and will require a lot of soldering. There isn't a standard way to accomplish this, but it is important to think about the way you'll route and solder the columns and rows. There are 22 microcontroller wires as well as pins to connect to this keyboard. It has five rows and 17 columns.

After the rows and column are soldered together, it is time to connect the key switches. To do this, put a diode over each pin on the key switch and then solder it. This will protect the pins on the key switch from current and keep them from being shorted. The diode will only allow the current to flow in a single direction, and it has the black band as a visual indicator that indicates the direction in which current will flow.

Sanabria says that a few of the tools available in auto parts stores, like the Autel MaxiIM IM608PRO or IM508 can assist shoppers or DIY users to program replacement keys and restore immobilizer information.

Jumpstarting the battery

Most people keep a set in their trunk to jump-start a vehicle in an emergency, but this might not be a good idea for cars with more modern technology. These vehicles are equipped with digital and computer systems that communicate with one another. A surge of voltage when the battery is connected to another one could cause damage to the parts and render your vehicle unusable.

Start the working vehicle and let it run for about two minutes before connecting the cables to the non-working one. Attach the red clip to the positive terminal of the battery that is good (it will have "POS" or "+" on it).

Do not connect the black cable to the negative terminal of the dead battery because this could trigger a spark that ignites the gasoline in the engine bay.
