Transponder key
The transponder is a type of key with an electronic chip. The chip sends a signal when the key is inserted in the ignition. The car then checks the signal to determine if it matches that of the key. If the signals match the car will then unlock itself and begin. This is a great method to avoid auto theft and keep your car secure from thieves.
Transponder keys are a popular feature in vehicles, but you should be aware that they aren't as secure as traditional keys made of metal. While the metal component of a traditional key can be cut and copied but a transponder key is protected by an electronic chip. The chip is equipped with an individual code that is embedded into the car's computer to identify it.
When a Saab key fob is used the car recognizes it and allows it to turn on. However, it is only able to do this if the key fob is equipped with a chip that is not modified that has been programmed to match the original. Otherwise, the car would reject the key and refuse to start.

There isn't a standard way to accomplish this, but it is important to think about how you will route and solder the rows and columns. There are 22 microcontroller wires and pins to connect to this keyboard. It has 5 rows and 17 columns.
Once the rows and columns are soldered, it's time to connect them to key switches. Solder a diode on each key switch pin. This will protect the pins from current and prevent them from being shortened. A diode permits current to only flow in one direction. It has a visual indicator of a black line that shows which way current will flow.
A few of the tools that are available at auto parts stores -- such as the Autel MaxiIM IM608 PRO and IM508 -- could assist customers at the shop or DIY users in some cases create replacement keys and restore the lost immobilizer's data, Sanabria says.

Jump-starting the battery
A lot of people keep a set of jumper cables in their trunk for emergencies, but jumping a battery in newer cars might not be the best choice. These vehicles have many digital and computer systems that communicate with each other.

The black cable should not be connected to the negative terminal of the dead battery. This could result in sparks that could ignite the gasoline that is in the engine compartment.
Once the cables are connected, you need to start the car and let it run about five minutes. Then disconnect them in reverse. Keep in mind that the battery on the Saab 9-3 gets recharged when you drive, so it will take a while to get the battery back to normal. It's a good idea buy a spare key fob as soon as you can, since replacing the only working one requires the installation of a brand new computer module and special programming to convince it that your lost keys aren't trying to steal the car.
