It's not a common way to go about it, but you should think about how to route and solder each column and row. There are 22 microcontroller wires and pins to connect for this keyboard. It has 5 rows and 17 columns.

After the columns and rows are soldered, it's time to connect them to the key switches. To do this, place a diode across each key switch pin and solder it. This will protect the pins from current, and prevent them from being shorted. A diode allows the current to flow in a single direction, and it comes with a an indicator of black color that shows the direction in which 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 cases replace keys in the program and restore lost saab key immobilizer data Sanabria says.

Don't connect the black cable to the negative terminal on the dead battery, since it could ignite an ignition source that ignites gasoline in the engine bay.
