saab key fob repair produced since 1994 use an immobilizer that relies on coded keys. To add an additional key, you need an entirely new transponder and programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool. This can be expensive. You should always keep an extra set of keys on hand. Transponder key The transponder key is a key with an electronic chip that sends a signal to the car when it is placed in the ignition. The car is able to check if the signal matches the one on the key. If the signals are identical, the car will unlock itself and start. This is a great way to avoid car theft and keep your vehicle safe from thieves. Transponder keys are an extremely popular accessory for cars, but they are not as secure as traditional keys made of metal. The metal part of the traditional key can be easily copied and cut, but a transponder has an electronic chip that guards it. The chip is a unique code that's programmed into a car's computer in order to identify it. When a Saab key fob is used, the car recognizes it and allows it to turn on. The car will 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 won't start. It's crucial to ensure that you have an extra key for your Saab. This is especially important if you reside in a rural region that has many car thieves. The good thing is that you can find a new key for your Saab without needing to visit an auto dealership and pay the high prices that they ask. You can get an original key made on the spot at a fraction of what you would spend at an auto dealer. Wired key Saab cars are usually supplied with two keys. If you have only one, it's an ideal idea to purchase an additional key fob as soon as is possible as if you lose it, your car will require the replacement of a CIM unit, and the locking cylinders have to be replaced. This can be costly especially if you're buying a second-hand car. The next step is to connect the wires for the column and row to the microcontroller. This is the toughest component of the project and will require lots of soldering. There is no standardized way to do this, but it is crucial to plan the way you'll route and solder the columns and rows. For this keyboard, there are five rows and 17 columns. This means there will be 22 microcontroller wires and pins that you need to connect. After the columns and rows are joined then it's time to connect the key switches. To do this, put an inverter over each pin on the key switch and solder it. This will protect the pins of the key switch from current and keep them from being shorted. A diode can only allow the current to flow in a single direction, and it also has a an indicator of black color that shows the direction in which current will flow. Some of the tools available at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 -- may help customers in the shop, or even DIY customers in certain instances programme replacement keys and recover lost immobilizer information, Sanabria says. The tools connect to the OBD port and automatically guide the customer through the process, making it more simple than replacing the computer in the vehicle. Jump-starting the battery The majority of people have an item in their trunk to jump start a car in an emergency, but this might not be the best option for vehicles with newer technology. These vehicles are equipped with a number of digital and computer systems that communicate with each other. A voltage surge while the battery is connected to another one could damage these components and leave your car undriveable. 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 read POS or +.) Attach the other end to a clean, unpainted metal surface beneath the hood of the damaged vehicle. The engine block is a good alternative. The black cable is not to be connected to the negative terminal of the dead battery. This could cause a spark, which would ignite the gasoline in the engine compartment. Once the cables are connected the disabled vehicle and let it run for approximately five minutes before disconnecting the cables in reverse order. The battery in your Saab 9-3 will recharge while you drive. It takes a while for it to return to its original state. You should purchase 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 usually have only one car key, and if that is lost, they will be charged. It's costly to add a key and requires replacing the CIM or TWICE for older models. In the event of theft or other catastrophe it is recommended to have an extra key. Even it's new it will not work. The majority of locksmiths won't be able to help when you only have one working key, and the dealer will charge top dollar to replace the computer in your car for a replacement. However, we can reset and re-program your computer's EEPROM to accept an alternative key without replacing the entire system. That can save you lots of money. It's also much less expensive than waiting until you lose your one key.
