Saab Key Programming Saab cars manufactured from 1994 have an immobilizer system 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 using a special Tech2 diagnostic tool. The problem is that this can be very expensive. Always keep an extra set of keys at hand. Transponder key The transponder can be described as a key with an electronic chip. This chip sends out a signal when the key is put into the ignition. saab 9-3 key replacement checks to see whether the signal matches the one on the key. If the signals are in sync, the car will unlock and start. This is a great way to prevent auto theft and keep your vehicle secure from thieves. Transponder keys are an increasingly popular feature for automobiles, but they are not as secure as traditional metal keys. The metal part of the traditional key can easily be cut and copied, however the transponder is protected by an electronic chip which protects it. The chip has a unique code embedded into the car's computer to identify it. When a Saab key fob is used, the car recognizes it and allows it to turn on. But, it's only able to do this if the key fob has a non-modified chip that has been programmed to match the original. The car will not start in the event that the key has not been programmed to match. It is crucial to have an extra Saab key. This is particularly important if you reside in a rural area that is home to numerous car thieves. The good news is that you can find a replacement key to your Saab without needing to visit a dealership and pay the hefty prices that they charge. In the majority of cases, you can have a brand new key made right on the spot at a fraction of the price of what you would pay at a dealer. Wired key Saab cars are usually supplied with two keys. If you own only one, you should get an extra key as soon as you can. This is because, if it's lost and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This could be expensive, especially if you are purchasing a used car. The next step is to wire the column and row wires to the microcontroller. This is the most challenging part of the project and will require a large amount of soldering. It's not a standard way to go about it, but you should think about how to route and solder each column and row. There are 22 microcontroller pins and wires to connect to this keyboard. It includes 5 rows and 17 columns. Once the rows and columns are soldered, it's time to connect them to key switches. Solder a diode on each key switch pin. This will protect the pins of the key switch from current and also prevent them from being shorted. A diode can only allow current to flow in one direction, and it also has a the black band as a visual indicator that indicates the direction in which 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 help shop customers or even DIY customers in certain cases create replacement keys and restore lost immobilizer data, Sanabria says. The tools connect to the OBD port and automatically guide the customer through the process, making it easier than replacing the computer inside the vehicle. Jump-starting the battery Most people keep a set of jumper cables in their trunk to use in an emergency however, jumping a battery on modern cars might not be the best choice. They have numerous digital and electronic devices that communicate with each other. A surge in voltage when a battery is hooked up to another one could damage the components and render your car unable to drive. Connect the cables to the vehicle that is working. Let it run for two minutes. Attach the red clip to the positive terminal on 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 is an ideal choice. Do not connect the black cable to the negative terminal of the dead battery because this could cause an ignition that ignites the gasoline in the engine bay. After the cables have been connected, you should start the vehicle and let it run for approximately five minutes. Then disconnect the cables in reverse. The battery in your Saab 9-3 is recharged while you drive. It takes a while for it to fall back. You should consider purchasing an additional key fob as soon as you can. The replacement of the one that works requires the installation and programming of a brand new computer chip. Replacement case Many Saab owners only have one key for their vehicle and if they lose it, key, it will cost them. The reason for this is that it's not inexpensive to buy a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. In the event of theft, or any other catastrophe, it is best to have an extra key. Even it's new, it will not function. The dealer will charge you top dollar if you only have one working key. We can reset and reprogram the computer's EEEPROM in order for it to accept a replacement key without replacing the entire system. This could save you a significant amount of money. It's also much less expensive than waiting until you lose the only key.
