Saab Key Programming
Saab cars that were built prior to 1994 feature an immobilizer mechanism made up of coded keys. A new transponder is required for inclusion of an additional key, and special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.
The problem is that this could be extremely expensive. It is always advisable to keep an extra set of keys on hand.
Transponder key
The transponder is a type of key that has an electronic chip. This chip sends out a signal when the key is inserted in the ignition. The car then analyzes the signal to see whether it matches the one that is in the key. If the signals match the car will then unlock itself and begin. This is a great way to deter auto theft and keep your vehicle safe from thieves.
Transponder keys are a common feature in cars, but you should be aware they aren't as secure as traditional keys made of metal. The metal component of a traditional key is easily cut or copied, while the transponder is protected by an electronic chip that safeguards it. This chip has a unique code programmed into the car's computer to identify it.
The car will recognize the saab replacement key programming keyfob, and allow it to turn on. The car can only recognize the key fob when it has a chip that is unmodified and programmed to match. The car won't start in the event that the key is not programmed to match.

The next step is to wire the wires for the column and row to the microcontroller. This is the most tedious part of the project, and will require a lot of soldering. It's not a common way to go about it, however, you should consider how to program saab 9-3 key fob you will connect and solder each column and row. There are 22 microcontroller wires and pins to connect to this keyboard. It includes 5 rows and 17 column.
Once the rows and columns are soldered, it's time to connect them to the key switches. To do this, put a diode across each key switch pin and solder it. This will protect the pins that are used for key switches from current and stop them from being shorted. A diode permits current to only flow in one direction. It features a visual indicator that is black, that indicates which direction current will flow.
Sanabria states that a number of the tools that are sold in auto parts stores, such as the Autel MaxiIM IM608PRO and IM508 are able to assist customers shopping or DIY customers to program replacement keys and restore the immobilizer's data. The tools connect to the OBD port and guide the customer through the procedure, making it simpler than replacing the computer inside the vehicle.
Jump-starting the battery
Most people keep a set of jumper cables in their trunks to use in an emergency however, jumping a battery on newer automobiles might not be the best option. These vehicles are equipped with many computers and digital devices which communicate with each other. A voltage spike when the battery is connected to another one could cause damage to the parts making your car inoperable.
Start the vehicle that is working and let it run for about two minutes before you connect the cables to the disabled one. Attach the red clip on the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end to a clean, unpainted metal surface underneath the hood of your disabled vehicle. The engine block is an excellent alternative. Don't connect the black cable to the negative terminal of the dead battery as this could cause an ignition source that ignites gasoline in the engine bay.
Once the cables are connected, start the vehicle and let it run about five minutes. Then, disconnect them in reverse. Remember that the battery on your Saab 9-3 is charged during your drive, which means it may take some time for the battery to come down. You should invest in another key fob as soon as you can. The replacement of the one that works requires the installation and programming of a new computer chip.

saab 900 key owners usually only have one car key, and if it is lost saab keys, they will be charged. The reason is that it's not inexpensive to purchase a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming.
