This means there will be 22 microcontroller wires and pins that you need to connect.

After the rows and column are joined It is now 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 being shortened. The diode will only allow the flow of current to be in one direction, and it comes with a an indicator in black that indicates which way the current will flow.

Some of the tools you can find at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- could assist customers at the shop or DIY users in some cases replace keys in the program and restore lost immobilizer information, Sanabria says.
