Saab Key Programming
Saab cars built since about 1994 come with an immobilizer system made up of coded keys. A new transponder is required to allow the inclusion of an additional key, and special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.
This can be expensive. This is the reason why you should always have a spare key available.
Transponder key
The transponder is a piece of key equipped with an electronic chip. The chip transmits a signal when the key is put into the ignition. The car will check to see whether the signal is the same as the one on the key. If the signals are in sync the car will then open and start. This is a great way to safeguard your car from theft.
Transponder keys may be an extremely popular accessory for cars, but they're not as secure as traditional metal keys. The metal portion of a traditional key can easily be cut and copied, however the transponder is protected by an electronic chip that protects it. The chip has a unique code that is inserted into a car's computer order to identify it.
The car will recognize the Saab keyfob and permit it to be turned on. However, it is only able to do this if the key fob has an unmodified chip that has been programmed to match the original. The car will not start in the event that the key is not programmed to match.
It is vital to have a spare Saab key. This is especially true for those who live in a rural region where there are a lot of car thieves.

This can be expensive, especially for used cars.
The next step is to connect the wires of columns and row to your microcontroller. This is the most laborious aspect of the project and it will require a lot of soldering. There's no standard way to accomplish this, however it is essential to determine the routes you'll use to solder the columns and rows. There are 22 microcontroller wires and pins to connect for this keyboard. It has 5 rows and 17 columns.
After the rows and column are soldered together, it is time to connect the key switches. Solder a diode to each key switch pin. This will shield the pins from current and prevent them from being shortened. A diode permits current to only flow in only one direction. It has a visual indicator of a black line that indicates which direction current will flow.
Some of the tools you can find 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 replace keys in the program and restore lost immobilizer information, Sanabria says. The tools plug into OBD ports and guide the user through each step and make the process more straightforward than replacing the car's computer.
Jumpstarting the battery
A lot of people keep an item in their trunks to jump-start their vehicle in the event of an emergency, but this might not be the best option for vehicles with newer technology.

Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end to a clear, unpainted metal surface under the hood of the affected car. The engine block is an excellent choice. Do not connect the black cable to the negative terminal of the dead battery, since it could ignite a spark that ignites the gasoline in the engine bay.
After the cables have been connected, you can start the vehicle and let it run for approximately five minutes. Then, disconnect them in reverse. The battery in your Saab 9-3 will recharge as you drive. It will take some time for it to fall back. You should consider purchasing another key fob when you can. Replacing the original one that works requires the installation and programming of a brand new computer chip.
Replacement case
Many Saab owners only have one key for their vehicle and if they lose that it's going to cost them. It's costly to add an additional key and it requires replacing the CIM or TWICE in the case of older models. In the event of theft or any other disaster, it is best to have a spare key. Even when the key is "new" it won't work.
Most locksmiths aren't able to help with a single working key, and the dealer will charge high fees to replace the computer in your vehicle to make a new replacement. We can, however, reset and reprogram the computer's EEPROM to accept the new key, without replacing the entire system. This can save you a lot of money. It's more affordable than wait until you lose the only key.
