For this keyboard, there are 5 rows and 17 columns, so 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. Solder a diode on each key switch pin. This will shield the pins from current, and prevent them from being cut off. The diode will only allow the flow of current to be in one direction, and it also has a the black band as a visual indicator that indicates which way the 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 are able to assist shoppers or DIY users to program replacement keys and restore data from the immobilizer.

Jump-starting the battery
A lot of people keep a set in their trunks to jump-start their vehicle in an emergency, but this might not be the best idea for newer cars. These cars have a variety of computers and digital devices that communicate with each other. A voltage spike when the battery is connected to another battery could fry these components, rendering your car unable to drive.
