Saab Key Programming Saab cars produced 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 by the dealer using a special Tech2 diagnostic tool. This can be expensive. This is the reason why you should always have a spare key available. Transponder key The transponder key is a piece of hardware equipped with an electronic chip. It transmits a signal to the car when it is inserted into the ignition. The car then analyzes the signal to see whether it matches the one on the key. If the signals match the car will then open and start. This is a great method to stop auto theft and keep your vehicle safe from thieves. Transponder keys could be an increasingly popular feature for cars, but they're not as secure as traditional keys made of metal. While the metal portion of a traditional key may be cut and copied but a transponder key is protected by an electronic chip. The chip has a unique code which is programmed into a car's computers in order to identify it. The car will recognize the Saab keyfob, and allow it to be turned on. However, it will only do this if the key fob has a non-modified chip that has been programmed to match. The car will not start in the event that the key is not programmed to match. It's essential to ensure that you have a spare key for your Saab. This is especially important for those who live in a rural region where there are numerous car thieves. The good thing is that you can find a new key for your Saab without having to go to an auto dealership and pay the high costs that they charge. In the majority of cases, you can have a new key created on-the-spot for less than half the price of what you'd pay at a dealer. Key for Wired Saab cars are usually provided with two keys. If you only have one, you should get an additional key as soon as you can. This is because if you lose it and the car needs a new CIM and the locking cylinders replaced. This could be expensive, especially if you are purchasing a used car. The next step is connecting the wires for columns and row to your microcontroller. This is the most tedious part of the project, and it will require lots 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 as well as pins to connect to this keyboard. It has five 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 key switch pins from current and keep them from being shorted. A diode allows current to only flow in one direction. saab 9-3 key fob programming comes with a visual indicator with a black band that shows which way current will flow. Some of the tools offered at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 — can help customers in the shop, or even DIY customers in certain cases program replacement keys and restore lost immobilizer data Sanabria says. The tools connect to OBD ports and help the customer through each step which makes the process much easier than replacing the vehicle's computer. Jumpstarting the battery Most people keep a set of jumper cables in their trunks to use in an emergency, but jumping a battery on newer vehicles might not be the best option. They have numerous digital and computer systems that communicate with one another. A voltage surge while a battery is hooked up to another battery could fry these components, rendering your vehicle unable to drive. Start the working vehicle and let it run for about two minutes before connecting the cables to the non-working one. 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 under the disabled car's hood. The engine block would be a good option. Do not connect the black cable to the negative terminal of the dead battery because this could trigger an ignition that ignites the gasoline in the engine bay. After the cables have been connected, you should start the car and let it run for about five minutes. Then disconnect them in reverse. The battery in your Saab 9-3 is recharged as you drive. It takes a while for it to fall back. You should consider purchasing an additional key fob when you can. Replacing the original 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 that they'll be charged. The reason is that it's costly to add a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It's recommended to have a backup key in case of theft or any other catastrophe, and the best way is to buy an extra key as early as you can. Don't buy a secondhand key, even when it's “new.” Keys that are claimed to be new from a second-hand store will not perform and are almost certain to fail in the most critical moment. The majority of locksmiths won't be able to help in the event that you only have one working key and the dealer will charge you high fees to replace the computer in your vehicle for a replacement. However, we can reset and re-program the computer's EEPROM to prepare it to accept the new key without having to replace the whole system. This could help you save a significant amount of money. It's also a lot cheaper than waiting until you lose your sole key.
