There isn't a standard method to go about it, however, you should plan How To Program Saab 9-3 Key Fob to connect and solder each column and row. 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, it's time to connect them to key switches. To do this, you need to place an inverter over each pin on the key switch and then solder it. This will shield the pins that are used for key switches from current and stop them from being shorted. A diode can only allow the current to flow in a single direction, and has a a black band visual indicator that indicates the direction current will flow.
Some of the tools available at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- can help shop customers or even DIY users in some cases create replacement saab 9-3 key keys and restore lost immobilizer data Sanabria says.
