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

After the columns and rows are joined, it is time to connect the key switches. To do this you must place an inverter over each pin on the key switch and then solder it. This will shield the pins from current and prevent them from getting shorted. A diode allows the flow of current to be in one direction, and it has an indicator of black color that indicates the direction in which current will flow.

Sanabria says that some of the tools sold in auto parts stores, like the Autel MaxiIM IM608PRO and the IM508 will 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 for emergency situations however, jumping a battery on newer vehicles might not be the most efficient option.
