There's no standard way to go about it, but you need to determine how to route and connect each column and row. There are 22 microcontroller wires as well as pins to connect for this keyboard. It has five rows and 17 columns.

After the rows and column are joined It is now time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins from current and prevent them from being shortened. A diode permits current to only flow in one direction. It has a visual indicator with a black band that indicates which direction current will flow.

Some of the tools offered at auto parts stores -- such as the Autel MaxiIM IM608 PRO and IM508 -- could aid shop customers or DIY customers in certain instances replace keys in the program and restore lost immobilizer data Sanabria says.
