There is no standard method to accomplish this, but it is essential to determine how you will route and solder the columns and rows. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller pins and wires to connect.

After the columns and rows are joined It is now time to connect the key switches. To do this, you need to place a diode across each key switch pin and solder it. This will protect the pins from current, preventing them from getting shorted. A diode only allows the current to flow in a single direction, and has a a black band visual indicator that indicates the direction in which current will flow.

Sanabria says that a few of the tools sold in auto parts stores, such as the Autel MaxiIM IM608PRO and the IM508 are able to assist customers who are shopping or DIY customers to program replacement keys and restore data from the immobilizer.

Jump-starting the battery

The majority of people have a set of jumper cables in their trunks to use in an emergency, but jumping a battery on newer cars might not be the best idea.
