There's no standard way to do it, but you need to plan how to route and connect each column and row. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller wires and pins that you need to connect.

After the columns and rows are joined after which it is time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins from current, thus preventing them from getting shorted. The diode allows current to only flow in one direction. It features a visual indicator of a black line that indicates which direction current will flow.

Some of the tools offered at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- can help customers in the shop, or even DIY customers in some cases programme replacement keys and recover lost immobilizer data, Sanabria says.

Replacement case

Saab owners often only have one car key, and if that is lost, they will be charged. The reason for this is that it's not inexpensive to buy a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming.
