There is no standardized way to do this, but it's important to plan out the route you'll take and solder the columns and rows. There are 22 microcontroller pins and wires to connect to this keyboard. It has five rows and 17 columns.

After the columns and rows are joined It is now time to connect the key switches. To do this, 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 cut off. A diode can only allow the current to flow in a single direction, and it also has a an indicator in black that indicates which way the current will flow.

Some of the tools you can find at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- can assist customers at the shop or DIY customers in certain instances replace keys in the program and restore the lost immobilizer's data, Sanabria says.

Once the cables are connected, you should start the vehicle and let it run for about five minutes. Then disconnect the cables in reverse. Be aware that the battery of the Saab 9-3 gets recharged while you drive, so it could take a while for the battery to go back down again. It's a good idea purchase a spare fob as soon as you can, because replacing the only functioning one requires the installation of a brand new computer module and special programming to convince the system that your lost keys aren't attempting to steal the car.
