Saab Key Programming

Saab cars made since 1994 have an immobilizer system that is based on codes for keys. A new transponder is required to allow the addition of an extra key, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

There's no standard way to accomplish this, but it is important to think about 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 5 rows and 17 column.

After the rows and column are soldered together It is now time to connect the key switches. To do this, place a diode on each key switch pin and solder it. This will shield the pins from current, preventing them from being cut off. The diode allows current to only flow in only one direction. It is equipped with a visible indicator that is black, that shows the direction in which the current will flow.

Sanabria states that a number of the tools available in auto parts stores, such as the Autel MaxiIM IMM608PRO and IM508 will assist customers shopping or DIY users to program replacement keys and restore data from the immobilizer. The tools connect to the OBD port and guide the user through the procedure, making it much easier than replacing the computer inside the vehicle.

Jump starting the battery

The majority of people have an assortment of tools in their trunks to start a car in case of emergency, but it might not be a good idea for vehicles that are newer.
