For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller wires and pins to connect.

After the columns and rows are soldered together then it's time to connect the key switches. To do this you must place a diode over each key switch pin and then solder it. This will shield the pins on the key switch from current and prevent them from being shorted. The diode will only allow the current to flow in a single direction, and it comes with 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, like the Autel MaxiIM IMM608PRO and IM508 will assist customers who are shopping or DIY users to program replacement keys and restore data from the immobilizer. The tools plug into OBD ports and help the customer through each step which makes the process much easier than replacing the car's computer.

Jump starting the battery

Most people keep a set of jumper cables in their trunk in case of emergency, but jumping a battery for newer vehicles may not be the best idea.

The reason for this is that it's not inexpensive to replace a key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming.
