Saab cars made since 1994 use an immobilizer that relies on a set of keys. The addition of a key requires an entirely new transponder and programming. This is usually done at the dealer using a Tech2 diagnostic tool.

The issue is that this can be very expensive. This is why you should always have a spare key at hand.

Transponder key

The transponder can be described as a key with an electronic chip. This chip sends a signal when the key is put into the ignition. The car is able to check if the signal matches the one on the key. If the signals are in sync then the car will be able to unlock and start. This is a great way to avoid auto theft and keep your vehicle safe from thieves.

Transponder keys can be an extremely popular accessory for cars, but they're not as secure as traditional keys made of metal. The metal portion of a traditional key can be easily cut or copied, while transponders are protected by an electronic chip which protects it. The chip is equipped with a unique code encoded into the car's system to identify it.

The car will recognize the Saab keyfob and allow it to be turned on. However, it is only able to do this if the fob has a non-modified chip that has been programmed to match the original. The car won't start in the event that the key has not been programmed to match.

The next step is to connect the row and column wires to the microcontroller. This is the most challenging part of the project and will require a large amount of soldering. There is no standard method to do this, but it is essential to determine the way you'll route and solder the columns and rows. There are 22 microcontroller wires and pins to connect to this keyboard. It has 5 rows and 17 columns.

After the rows and column are joined It is now time to connect the key switches. To do this, place a diode across each pin on the key switch and solder it. This will protect the pins from current, preventing them from being cut off. A diode permits current to only flow in only one direction. It comes with a visual indicator with a black band that shows the direction in which the current will flow.

Some of the tools available at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- may help customers in the shop, or even DIY customers in some cases replace keys in the program and restore lost saab keys (blog post from Faitalia Co) immobilizer data, Sanabria says.

Jumpstarting the battery

Most people keep a set of jumper cables in their trunk to use in an emergency, but jumping a battery in newer vehicles may not be the best idea. These vehicles are equipped with a number of digital and electronic devices that communicate with one another. A surge in voltage while the battery is connected to another can fry these components and leave your car undriveable.

Start the vehicle that is working and allow it to run for approximately two minutes before you connect the cables to the disabled one. Attach the red clip to the positive terminal on the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clean and unpainted metal surface beneath the hood of the affected vehicle. The engine block is a great option. Don't connect the black cable to the negative terminal on the dead battery as it could ignite an ignition spark that ignites the gasoline in the engine bay.

Once the cables are connected the disabled vehicle and let it run for approximately five minutes before you disconnect the cables in reverse order. The battery in your Saab 9-3 is recharged as you drive. It takes a while for it to fall back. You should purchase another key fob as soon as you can. Replacing the original one that works requires the installation and programming of a new computer chip.

Replacement Case

Saab owners usually have only one car key, and if it is lost, they'll be charged. The reason is that it's not inexpensive to replace a key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft or any other disaster, it is best to have a spare key. Even even if the key is "new" it won't work.
