Saab Key Programming
Saab cars manufactured since 1994 feature an immobilizer system based on key codes. A new transponder is required for the addition of a second key, as well as special programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.
The issue is that this can be quite costly. You should always keep a spare set of keys available.
Transponder key
The transponder can be described as a key with an electronic chip. The chip transmits a signal when the key is put in the ignition. The car will check to see whether the signal matches with the one on the key. If the signals are the same the car will then unlock itself and start. This is a great method to stop car theft and keep your car secure from thieves.
Transponder keys are an increasingly popular feature for cars, but they're not as safe as traditional metal keys. The metal component of a traditional keys can be easily cut or copied, while transponders have an electronic chip which protects it. The chip has a unique code that is encoded into the car's system to identify it.
The car will recognize the Saab keyfob and permit it to turn on. However, it can only do this if the fob has a non-modified 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's essential to ensure that you have an extra key for your saab key programmer. This is particularly important when you live in a rural area with many car thieves. You can obtain a replacement key for your Saab by visiting the dealership without paying their high costs. In most cases, you can have a new key created on-the-spot for less than half the cost of what you'd pay at a dealer.
Key for Wired
Saab cars typically come with two keys when they are new. If you have only one, it is a good idea to get an extra key fob as soon as you can since if you lose it, the car will require a new CIM unit and the locking cylinders have to be replaced. This can be expensive particularly for used cars.
The next step is to wire the column and row wires to the microcontroller. This is the most challenging part of the project and will require a good deal of soldering. There is no standard method to accomplish this, however it is important to think about the routes you'll use to solder the columns and rows. There are 22 microcontroller wires and pins that you can connect to this keyboard. It has 5 rows and 17 column.
After the columns and rows are joined, it is time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins from current and prevent them from being shorted. The diode will only allow the flow of current to be in one direction, and it also has a an indicator in black that indicates the direction current will flow.
Sanabria says that some of the tools available in auto parts stores, like the Autel MaxiIM IM608PRO or IM508 are able to assist customers shopping or DIY users to program replacement keys and restore immobilizer data. The tools connect to the OBD port and automatically guide the customer through the procedure, making it much easier than replacing the computer inside the vehicle.
Jump-starting the battery
A lot of people keep the set in their trunk to start a car in an emergency, but it may not be a good idea for newer cars. These cars have a variety of computers and digital devices that communicate with one another. A voltage surge when the battery is connected to another can fry the components, rendering your car undriveable.
Connect the cables to the vehicle that is working. Let it run for two minutes. Attach the red clip to the positive terminal of the battery that is good (it will have "POS" or "+" on it). Attach the other end of the black cable to a clean, unpainted metal surface underneath the car's hood. The engine block would be a good choice. The black cable should not be connected to the negative terminal of the dead battery. This could result in sparks, which would ignite the gasoline inside the engine compartment.
Once the cables are connected, start the vehicle that has been disabled and let it run for about five minutes before you disconnect them in reverse order. The battery in your Saab 9-3 will recharge while you drive. It will take a while for it to return to its original state. It's a good idea purchase a spare key fob as soon as you can, since replacing the sole working one requires the installation of a new computer module and a special program to convince the system that your lost keys aren't attempting to steal the car.
Replacement case
Many Saab owners have only one key for their car and if they lose it, the cost will be. The reason is that it's not inexpensive to purchase a new 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 catastrophe it is best to have a spare key. However, don't purchase a secondhand key even the case that it's "new." Keys that are claimed to be new from aftermarket sellers will not perform and are almost certain to fail at the crucial moment.
Most locksmiths aren't able to help when you only have one working key and the dealer will charge high prices to replace the computer in your car to create a replacement. We can, however, reset and re-program the computer's EEPROM to prepare it to accept the new key, without replacing the whole system. That can save you lots of money. It's also a lot cheaper than waiting until you lose your one key.
