Saab Key Programming

There are 22 microcontroller wires as well as pins to connect to this keyboard. It has five rows and 17 column.
After the rows and column are soldered together then it's time to connect the key switches. To do this you must place a diode across each pin on the key switch and then solder it.

Some of the tools available at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- could assist customers at the shop or DIY customers in some cases programme replacement keys and recover lost immobilizer information, Sanabria says.

Jump starting the battery
Most people keep a set of jumper cables in their trunks in case of emergency however, jumping a battery for newer cars might not be the best idea. These cars are equipped with a variety of digital and computers that communicate with each other. A voltage spike when a battery is hooked up to another can fry these components and leave your vehicle undriveable.
Connect the cables to the vehicle operating. Let it run for two minutes. Attach the red clip on the positive terminal of the good battery. (It will say "POS" or "+".) Attach the other end to a clear, unpainted metal surface beneath the hood of the affected car. The engine block is an excellent choice. Do not connect the black cable to the negative terminal on the dead battery, as it could spark an ignition spark that ignites the gasoline in the engine bay.
Once the cables are connected, turn on the vehicle you are not using and allow it to run for around five minutes before disconnecting the cables in reverse order. Keep in mind that the battery on your Saab 9-3 is recharged during your drive, which means it may take some time to get the battery back down again. It's a good idea to purchase a spare key fob as soon as you can, because replacing the only working one requires the installation of a brand new computer module and a special program to convince it that your missing keys are not trying to steal the car.
Replacement case
Saab owners usually only have one car key, and if it is lost, they will be charged. The reason for this is that it's expensive to purchase a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. In the event of theft, or any other calamity, it is best to have an extra key. Don't buy a secondhand key even when it's "new." Keys that are claimed as new from sellers selling aftermarket keys won't be effective and are almost guaranteed to fail at the crucial moment.
Most locksmiths cannot help you when you only have one working key and the dealer will charge high fees to replace the computer in your car to make a replacement. However, we can reset and re-program the computer's EEPROM to prepare it to accept a new key without replacing the whole system. This could save you a significant amount of money. It's less expensive than wait until you lose your only key.
