Saab Key Programming Saab cars built from 1994 have an immobilizer system that relies on a set of keys. To add an additional key, you need an entirely new transponder and programming. This is usually done by the dealer using a Tech2 diagnostic tool. The problem is that this can be very expensive. This is why it is important to always have a spare key at hand. Transponder key The transponder key is a key with an electronic chip that sends a signal back to the car when it is inserted into the ignition. The car checks to see whether the signal matches with the one on the key. If the signals are in sync it will unlock and begin. This is a great way to deter auto theft and keep your vehicle safe from thieves. Transponder keys are a common feature in automobiles, but you should be aware that they're not as secure as classic keys made of metal. The metal portion of a traditional key is easily copied and cut, but transponders have an electronic chip that safeguards it. The chip has an unique code that is programmed into the car's computers to identify it. The car will recognize the Saab keyfob, and allow it to turn on. However, it will only do this if your key fob is unmodified and has a chip that has been programmed to match. Otherwise, the car would reject the key and not start. It's important to make sure that you have an extra key for your Saab. This is especially true for those who live in a rural location that has numerous car thieves. You can get a new key for your Saab by visiting the dealership, without having to pay their pricey prices. In the majority of cases, you can have an original key made on the spot at a fraction of the cost of what you would pay at the dealer. Wired key Saab cars usually come with two keys when new. If you have only one, it's a good idea to get an extra key fob as soon as possible in case you lose it, the car will require an entirely new CIM unit, and the locking cylinders need to be replaced. This can be costly especially if you're buying a used car. The next step is to connect the wires of the column and row to the microcontroller. This is the most laborious part of the project and will require lots of soldering. There's no standard way to accomplish this, but it is essential to determine how you will route and solder the rows and columns. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller pins and wires to connect. After the rows and column are soldered together It is now time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins from current, preventing them from being cut off. A diode can only allow the current to flow in a single direction, and it has an indicator in black that indicates the direction current will flow. A few of the tools that are available at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- could aid shop customers or DIY customers in some cases program replacement keys and restore the lost immobilizer's data, Sanabria says. saab key repair connect to the OBD port and automatically guide the customer through the procedure, making it much easier than replacing the computer in the vehicle. Jump-starting the battery The majority of people have the set in their trunks to jump start a car in case of emergency, but it may not be the best idea for newer cars. These vehicles are equipped with many digital and computer systems that communicate with each other. A voltage spike when a battery is connected to another battery could damage the components making your car unusable. Start the vehicle that is working and allow it to run for around two minutes before you connect the cables to the disabled one. Attach the red clip to the positive terminal of the battery that is good. (It will read POS or +.) Attach the other end of the black cable to an unpainted, clean metal surface under the disabled car's hood. The engine block would be an excellent choice. The black cable is not to be connected to the negative terminal of the dead battery. This could result in a spark, which would ignite gasoline in the engine compartment. Once the cables are connected, start the car and let it run for approximately five minutes. Then, disconnect them in reverse. Keep in mind that the battery on your Saab 9-3 is recharged while you drive, so it will take a while to get the battery down. You should purchase a second key fob, as soon as possible. Replacing the original one that works requires the installation and programming of a new computer chip. Replacement Case Saab owners typically only have one car key, and if it is lost, they'll be charged. The reason is that it's not inexpensive to add a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It's recommended to have a second key in case of theft or any other catastrophe and the most effective way is to purchase an additional key as quickly as you can. Don't purchase a used key, even it's new. Keys that are claimed-new from sellers selling aftermarket keys won't be effective and are almost guaranteed to fail in the most critical moment. Most locksmiths can't help you in the event that you only have one working key, and the dealer will charge you for the cost of replacing the computer in your car for a replacement. However, we can reset and re-program your computer's EEPROM in order to prepare it to accept an alternative key without replacing the entire system. This can save you a significant amount of money. It's much cheaper than wait until you lose the only key.
