Saab Key Programming Saab cars built since about 1994 feature an immobilizer mechanism made up of coded keys. A new transponder is required in order to enable the addition of a second key, as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool. It can be costly. This is the reason why you should always have a spare key on hand. Transponder key The transponder can be described as a key that is equipped with an electronic chip. This chip sends out a signal when the key is placed into the ignition. The car then analyzes the signal to see if it matches the one on the key. If the signals are the same it will open itself and begin. This is a great method to avoid car theft and keep your car secure from thieves. Transponder keys are a favored feature in automobiles, however you must be aware that they aren't as secure as traditional metal keys. The metal component of the traditional keys can be easily cut and copied, whereas the transponder is protected by an electronic chip which protects it. The chip has a unique code which is programmed into a car's computers in order to identify it. When a Saab key fob is used the car recognizes it and allows it to turn on. However, it is only able to do this if your key fob is unmodified and has a chip that has been programmed to match it. The car will not start if the key is not programmed to match. It is crucial to have a spare Saab key. This is especially important if you reside in a rural area that is home to many car thieves. You can purchase a new key for your Saab by visiting the dealership without paying their expensive prices. You can have a replacement key made on the spot for less than half the cost you would pay at an auto dealer. Key for Wired Saab cars are typically delivered with two keys. If you have only one, it is an ideal idea to purchase an extra key fob as soon as you can in case you lose it, the car will require the replacement of a CIM unit, and the locking cylinders will have to be replaced. This could be expensive, especially if you are 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 requires a significant amount of soldering. There isn't a standard way to accomplish this, but it is important to think about the routes you'll use to solder the rows and columns. There are 22 microcontroller wires as well as 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. Solder a diode on each key switch pin. This will protect the pins from current, preventing them from being shortened. The diode allows current to only flow in only one direction. It has a visual indicator, a black band, that indicates the direction in which current will flow. Some of the tools available at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- could help shop customers or even DIY customers in certain cases create replacement keys and restore lost immobilizer information, Sanabria says. The tools plug into OBD ports and help the customer through each step, making the process easier than replacing the car's computer. Jump-starting the battery A majority of people keep a set in their trunk to start a vehicle in an emergency, however it might not be a good option for vehicles with newer technology. These vehicles are equipped with many digital and computers that communicate with each other. A surge in voltage while the battery is connected to another one could damage these components, rendering your vehicle unable to drive. Start the vehicle you are using and let it run for about two minutes before connecting the cables to the battery that is not working. Attach the red clip on the positive terminal of the battery that's good. (It will say POS or +.) Attach the other end to a clear, unpainted metal surface under the hood of the damaged vehicle. saab 9-3 replacement key is a great alternative. Do not connect the black cable to the negative terminal on the dead battery as it could spark 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 the cables in reverse. Remember that the battery on your Saab 9-3 is recharged when you drive, and it can take a while for the battery to come back to its original level. You should invest in an additional key fob as soon as possible. Replacing the only one that works requires the installation and programming of a brand new computer chip. Replacement Case Many Saab owners have only one key for their vehicle and if they lose it, key, it will cost them. It's expensive to purchase an additional key and it requires replacing the CIM or TWICE in the case of older models. It's best to have a spare key in the event of theft or any other catastrophe and the most effective way is to purchase an extra key as soon as you can. However, don't purchase a secondhand key, even when it's new. Keys that are claimed as new from sellers selling aftermarket keys won't work and are almost guaranteed to fail in the crucial moment. Most locksmiths aren't able to help with a single working key and the dealer will charge you for the cost of replacing the computer in your car for a replacement. We can reset and reprogram the EEEPROM of your computer to make it ready to accept a replacement key without the need to replace the entire system. This can help you save money. It's cheaper to do this than waiting until you loose the only key.
