Saab Key Programming
saab 93 key replacement cars built since about 1994 come with an immobilizer system that is based on codes for keys. A new transponder is required for the addition of a second key, and special programming. This is usually done by the dealer using a Tech2 diagnostic tool.
The issue is that it can be extremely expensive. This is why you should always keep a spare key in your possession.
Transponder key
The transponder key is a piece of hardware equipped with an electronic chip. It sends a signal to the car when it is placed in the ignition. The car will check to see whether the signal matches with the one on the key. If both signals match, the car will unlock itself and start. This is a great method to stop auto theft and keep your vehicle safe from thieves.
Transponder keys could be a popular addition to cars, but they are not as safe as traditional keys made of metal. While the metal part of a traditional key could be cut and copied however, a transponder is secured by an electronic chip. The chip is a unique code that is programmed into a car's computer in order to identify it.
When a Saab key fob is used the car recognizes it and allows it to turn on. However, it will only do so 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 has not been programmed to match.
It is essential to have a spare saab key programmer key. This is particularly important if you live in a rural region where there are a lot of car thieves. The good part is that you can obtain a replacement key for your saab 9 3 key replacement without having to go to an auto dealership and pay the expensive prices that they demand. You can have a replacement key made on the spot for less than half what you would spend at a dealership.
Key for Wired
Saab cars are usually supplied with two keys. If you have only one, it is best to acquire an additional key fob as soon as possible in case you lose it the car will require a new CIM unit, and the locking cylinders have to be replaced. This could be expensive especially if purchasing a used car.
The next step is to connect the wires of columns and row to your microcontroller. This is the most challenging part of the project and will require a large amount of soldering. There is no standard method to accomplish this, but it is crucial to plan how you will route and solder the columns and rows. There are 22 microcontroller pins and wires to connect for this keyboard. It has 5 rows and 17 column.
After the columns and rows are soldered together It is now time to connect the key switches. To do this you must place a diode across each key switch pin and solder it. This will shield the pins on the key switch from current and stop them from being shorted. A diode allows current to only flow in only one direction. It features a visual indicator that is black, that shows which way current will flow.
Sanabria says that some of the tools that are sold in auto parts stores, such as the Autel MaxiIM IMM608PRO and IM508 can assist shoppers or DIY customers to program replacement keys and restore immobilizer data. The tools connect to the OBD port and automatically guide the user through the procedure, making it much easier than replacing the computer inside the vehicle.
Jump starting the battery
The majority of people have a set of jumper cables in their trunks for emergency situations however, jumping a battery on modern automobiles might not be the best option. They have numerous electronic devices and computers that communicate with one another. A surge of voltage when a battery is connected to another battery could damage the components making your car unusable.
Connect the cables to the vehicle that is operating. Allow it to run for two minutes. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to a clean, unpainted metal surface underneath the disabled car's hood. The engine block is an ideal choice. The black cable is not to be connected to the negative terminal of the dead battery. This could trigger sparks, which would ignite gasoline in the engine compartment.
Once the cables are connected, you should start the vehicle and let it run about five minutes. Then, disconnect them in reverse. Keep in mind that the battery on your saab 9-3 key programming (i was reading this) 9-3 is charged when you drive, and it will take a while for the battery to go back to normal. It's a good idea purchase a spare fob as soon as you can, since replacing the one that works requires the installation of a new computer module and special programming to convince it that your missing keys aren't attempting to steal the car.

We can reset and reprogram the computer's EEEPROM for it to accept a replacement key without the need to replace the entire system. This could save you a significant amount of money. It's also cheaper than waiting until you lose your sole key.
