Saab Key Programming Saab cars made since 1994 utilize an immobilizer that relies on key codes. A new transponder is required to allow the inclusion of an additional key, as well as special programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool. The issue is that this can be very costly. Always keep a spare set of keys at hand. Transponder key The transponder key comes with an electronic chip that sends a signal back to the car when it is put into the ignition. The car then examines the signal to see if it matches that of the key. If the signals match then the car will be able to unlock and start. This is a great method to protect your car from theft. Transponder keys can be a popular addition to automobiles, but they are not as safe as traditional keys made of metal. The metal component of the traditional keys can be easily copied and cut, but transponders have an electronic chip that protects it. The chip is a unique code that is programmed into a car's computer in order to identify it. The car will recognize the Saab keyfob and permit it to be turned on. But, it's only able to do this if the fob is equipped with a chip that is not modified that has been programmed to match it. If not, the car will reject the key and not start. It's crucial to ensure that you have a spare key for your Saab. This is especially true if you reside in a rural area with numerous car thieves. saab key replacement cost can purchase a new key for your Saab by visiting the dealership and not paying their high cost. You can get a replacement key created on the spot at a fraction of the price you'd pay at an auto dealer. Key for Wired Saab cars usually come with two keys when they are new. If you have only one, it is best to acquire an extra key fob as soon as is possible in case you lose it, your car will require the replacement of a CIM unit, and the locking cylinders will need to be replaced. This can be costly particularly if you are buying a used car. The next step is to connect the wires of the column and row to the microcontroller. This is the most difficult part of the project and will require a good amount of soldering. There is no standard method to accomplish this, however it is essential to determine how you will route and solder the rows and columns. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins that you need to connect. After the rows and column are soldered together, it is time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins that are used for key switches from current and prevent them from being shorted. A diode allows the current to flow in a single direction, and it also has a a black band visual indicator that indicates the direction in which current will flow. Sanabria says that a few of the tools sold in auto parts stores, such as the Autel MaxiIM IMM608PRO and IM508 can assist customers who are shopping or DIY users to program replacement keys and restore the immobilizer's data. The tools connect to OBD ports and help the customer through each step and make the process more straightforward than replacing the vehicle's computer. Jump starting the battery A lot of people keep a set of jumper cables in their trunk in case of emergency, but jumping a battery on modern vehicles might not be the most efficient option. These vehicles have many digital and computer systems that communicate with each other. A surge in voltage when the battery is connected to another one could damage the components and render your vehicle undriveable. Start the vehicle that is working and allow it to run for approximately two minutes before connecting the cables to the disabled one. 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 would be an ideal choice. The black cable is not to be connected to the negative terminal of the dead battery. This could create sparks, which could ignite gasoline in the engine compartment. After the cables have been connected, you should start the vehicle and let it run about five minutes. Then disconnect the cables in reverse. Be aware that the battery in the Saab 9-3 will be charged when you drive, so it will take a while for the battery to come back to its original level. It's a good idea buy a spare key fob as soon as you can, since replacing the only working one requires the installation of a new computer module and a special program to convince it that your missing keys aren't trying to steal the car. Replacement case Many Saab owners only have one key for their car and if they lose it, the cost will be. The reason for this is that it's costly to replace a key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It is best to have a second key in the event of theft or other disaster, and the best way is to purchase an additional key as soon as you can. Even when the key is “new”, it won't work. 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 top dollar to replace the computer in your car to make a new replacement. We can reset and reprogram the computer's EEEPROM in order to be able to accept a replacement key without having to replace the entire system. This could help you save money. It's more affordable rather than wait until you loose the only key.
