Saab Key Programming Saab cars that were built prior to 1994 feature an immobilizer mechanism that is based on codes for keys. A new transponder is required in order to enable the addition of an extra key, as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool. This can be expensive. Always keep a spare set of keys 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 checks to see if the signal matches the one on the key. If the signals are identical, the car will unlock itself and begin. This is an excellent way to safeguard your car from theft. Transponder keys may be an increasingly popular feature for automobiles, but they are not as secure as traditional metal keys. While the metal portion of a traditional key may be cut and copied the transponder is protected by an electronic chip. The chip is a unique code that is inserted 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. how to open a saab 93 without a key can only recognize the key fob if it is equipped with a chip that is unmodified and has been programmed to match. If not, the car will reject the key and refuse to start. It is crucial to have a spare Saab key. This is especially true especially if you live in a rural location that has numerous car thieves. The good part is that you can obtain a replacement key for your Saab without needing to visit an auto dealer and pay the high costs that they charge. In the majority of instances, you can get a new key created on-the-spot at a fraction of the cost of what you'd pay at dealerships. Wired key Saab cars typically come with two keys upon purchase. If you only own one, you should purchase an additional key as fast as you can. This is because if it's lost the car will require a new CIM and the locking cylinders replaced. This can be costly especially if purchasing a used vehicle. The next step is to connect the row and columns wires to your microcontroller. This is the most challenging part of the project and will require a great deal of soldering. There isn't a standard way to do this, but it's important to plan out the routes you'll use to solder the rows and columns. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins that you need to connect. After the columns and rows are soldered, it's the time to connect them to the key switches. To do this, place a diode over each pin on the key switch and then solder it. This will protect the key switch pins from current and stop them from being shorted. A diode lets current only flow in one direction. It is equipped with a visible indicator with a black band that indicates the direction in which current will flow. Sanabria says that some of the tools available in auto parts stores, like the Autel MaxiIM IM608PRO and IM508, can help customers who are shopping or DIY customers to program replacement keys and restore the immobilizer's data. The tools plug into OBD ports and guide the user through each step, making the process easier than replacing the vehicle's computer. Jump-starting the battery A lot of people keep a set of jumper cables in their trunks for emergency situations however, jumping a battery on modern vehicles may not be the best option. These vehicles are equipped with computers and digital devices which communicate with one another. A voltage surge while a battery is hooked up to another battery could fry these components and leave your vehicle unable to drive. Connect the cables to the vehicle operating. Allow it to run for two minutes. Attach the red clip to the positive terminal of the battery that's good. (It will say POS or +.) Attach the other end to a clear, unpainted metal surface beneath the hood of the affected vehicle. The engine block is a good alternative. The black cable should not be connected to the negative terminal of the dead battery. This could result in a spark, which would ignite the gasoline that is in the engine compartment. Once the cables are connected, you need to start the vehicle and allow it to run for around five minutes. Then, disconnect the cables in reverse. Be aware that the battery in your Saab 9-3 is recharged when you drive, so it may take some time to get the battery back down again. You should consider purchasing a second key fob, when you can. Replacing the original one that works requires the installation and programming of a new computer chip. Replacement case Saab owners often only have one car key, and if that is lost, they will be charged. The reason is that it's expensive to buy a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. It is best to have a backup key in case of theft or any other catastrophe the best solution is to purchase an additional key as quickly as you can. Even it's new it will not function. 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 high fees to replace the computer in your vehicle for a replacement. We can reset and reprogram the computer's EEEPROM to get it ready to accept a new key without the need to replace the entire system. This could help you save money. It's less expensive instead of waiting until you lose your only key.
