Saab Key Programming Saab cars manufactured since 1994 have an immobilizer feature that is based on codes for keys. A new transponder is required for the addition of a second key, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool. It can be costly. This is the reason why you should always have a spare key on hand. Transponder key The transponder is a piece of key that has an electronic chip. This chip sends out a signal when the key is placed into the ignition. The car will check to see if the signal matches the one on the key. If the signals match it will open itself and begin. This is a great method to stop car theft and keep your car safe from thieves. Transponder keys are a favored feature in automobiles, however you should be aware they're not as secure as classic keys made of metal. While the metal part of a conventional key can be cut and copied, a transponder is protected by an electronic chip. The chip has an individual code that is encoded into the car's system 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 programmed to match. In the absence of that, the car will reject the key and not start. It's essential to ensure that you have a spare key for your Saab. This is especially important when you live in a rural area with many car thieves. You can purchase a new key for your Saab by visiting the dealership without paying pricey costs. You can get a replacement key made on the spot for less than half of the price you'd pay at a dealership. Key for Wired Saab cars typically come with two keys when they're new. If you have only one, it's a good idea to get an extra key fob as quickly as you can as if you lose it, the car will require a new CIM unit and the locking cylinders have to be replaced. This can be costly, especially for used cars. The next step is to wire the row and column wires to the microcontroller. This is the most difficult part of the project and will require a good deal of soldering. There isn't a standard method to do it, however, you should consider how you will connect and solder each column and row. 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 rows and column are joined after which it is time to connect the key switches. To do this you must place an inverter over each pin of the key switch and solder it. This will shield the pins from current, preventing them from getting shorted. A diode lets current only flow in one direction. It is equipped with a visible indicator with a black band that indicates which direction current will flow. Sanabria says that some of the tools sold in auto parts stores, like the Autel MaxiIM IM608PRO or IM508, can help customers who are shopping or DIY customers to program replacement keys and restore data from the immobilizer. The tools plug into OBD ports and guide the user through each step making the process simpler than replacing the car'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 newer vehicles may not be the best option. These vehicles have many electronic devices and computers that communicate with one another. A surge of voltage when the battery is connected another can fry the components making your car unusable. Connect the cables to the vehicle that is operating. Allow replacement key for saab 93 to run for two minutes. Attach the red clip on the positive terminal of the battery that is good. (It will say POS or +.) Attach the other end of the black cable to a clean, unpainted metal surface beneath the damaged vehicle's hood. An engine block is an excellent choice. The black cable is not to be connected to the negative terminal of the dead battery. This could result in sparks that could ignite the gasoline that is in the engine compartment. Once the cables are connected, you can start the vehicle you are not using and let it run for about five minutes before you disconnect them in reverse order. The battery in your Saab 9-3 will be recharged as you drive. It takes a while for it to recharge again. It is recommended to purchase a second key fob, as soon as possible. Replacing the only one that works requires the installation and programming of a brand 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 add a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. In the event of theft, or any other disaster it is best to have an extra key. However, don't purchase a secondhand key even it's new. Keys that are claimed-new from sellers selling aftermarket keys won't perform and are almost certain to fail in the most critical moment. Most locksmiths aren't able to help when you only have one working key, and the dealer will charge you for the cost of replacing the computer in your vehicle to make a new replacement. We can reset and reprogram the computer's EEEPROM in order for it to accept a replacement key without having to replace the entire system. That can save you a lot of money. It's also cheaper than waiting until you lose your only key.
