Saab Key Programming
saab ignition key cars built since 1994 use an immobilizer system that relies on keys that are coded. The addition of a key requires a new transponder, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.
It can be costly. This is why it is important to always keep a spare key in your possession.
Transponder key
The transponder is a key that has an electronic chip. This chip sends out a signal when the key is put into the ignition.

This is a great method to prevent car theft and keep your vehicle safe from thieves.
Transponder keys may be an increasingly popular feature for cars, but they're not as safe as traditional metal keys. While the metal component of a conventional key can be cut and copied the transponder is protected by an electronic chip. The chip contains a unique code that's programmed into a car's computer order to identify it.
The car will recognize the Saab keyfob, and allow it to be turned on. But, it's only able to do this if your key fob has an unmodified chip that has been programmed to match. The car won't start when the key isn't programmed to match.

The next step is to connect the wires for columns and row to your microcontroller. This is the most challenging part of the project and will require a great amount of soldering. There isn't a standard way to do this, but it is important to think about the way you'll route and solder the columns and rows. There are 22 microcontroller wires and pins that you can connect to this keyboard. It has five rows and 17 columns.
After the columns and rows are soldered, it's the time to connect them to key switches. Solder a diode to each key switch pin. This will shield the pins of the key switch from current and stop them from being shorted. A diode only allows the current to flow in a single direction, and it comes with a a black band visual indicator that indicates the direction current will flow.
Some of the tools available at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 -- may assist customers at the shop or DIY customers in certain instances create replacement keys and restore lost immobilizer data, Sanabria says. The tools connect to the OBD port and automatically guide the user through the procedure, making it much easier than replacing the computer inside the vehicle.
Jump-starting the battery
Most people keep the set in their trunk to start a car in an emergency, but it may not be the best idea for newer cars.

The black cable is not to be connected to the negative terminal of the dead battery. This could result in sparks, which could ignite the gasoline in the engine compartment.
