Saab Key Programming Saab cars manufactured since 1994 utilize an immobilizer system based on keys that are coded. 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 a Tech2 diagnostic tool. It can be costly. This is why it is important to always keep a spare key in your possession. Transponder key The transponder key is a piece of hardware equipped with an electronic chip. It sends a signal back to the car when it is inserted into ignition. The car checks to see if the signal matches the one on the key. If the signals match, the car will unlock and start. This is a great way to protect your car from theft. Transponder keys are a popular feature in automobiles, however you should be aware that they're not as secure as classic metal keys. The metal portion of a traditional key can easily be copied and cut, but the transponder is protected by an electronic chip which protects it. The chip contains a unique code that is programmed into a car's computer order to identify it. The car will recognize the Saab keyfob and permit it to be turned on. The car can only recognize the key fob if the device has a chip that is unmodified and has been programmed to match. Otherwise, the car would refuse to accept the key and will not start. It's essential to ensure that you have an extra key for your Saab. This is especially true especially if you live in a rural area that is home to numerous car thieves. The good part is that you can obtain a replacement key for your Saab without having to go to an auto dealership and pay the high prices that they charge. You can get an original key made on the spot for less than half of the cost you would pay at a dealership. Wired key Saab cars are usually provided with two keys. If you own only one, you should purchase an additional key as soon as you can. This is because, if it's lost and the car needs a new CIM and the locking cylinders replaced. This can be costly particularly for used cars. The next step is connecting the row and columns wires to your microcontroller. This is the toughest part of the project and will require lots of soldering. There isn't a standard method to go about it, but you must consider how you will connect and solder each column and row. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller wires and pins to connect. Once the rows and columns are soldered, it's the time to connect them to key switches. To do this, put a diode on each pin of the key switch and solder it. This will protect the pins that are used for key switches from current and stop them from being shorted. A diode allows current to flow in one direction, and it comes with a an indicator of black color that shows the direction in which current will flow. Some of the tools you can find at auto parts stores -- such as the Autel MaxiIM IM608 PRO and IM508 -- may aid shop customers or DIY users in some cases program replacement keys and restore lost immobilizer information, Sanabria says. replacement saab key connect to OBD ports and guide the user through each step, making the process easier than replacing the car's computer. Jump-starting the battery Most people keep a set in their trunk to jump start a vehicle in an emergency, however it might not be a good idea for cars with more modern technology. These cars are equipped with a variety of digital and computer systems that communicate with each other. A voltage spike when the battery is connected to another battery could damage the components and render your vehicle unusable. Connect the cables to the vehicle operating. Allow it to run for two minutes. Attach the red clip on the positive terminal of the good battery. (It will read POS or +.) Attach the other end of the black cable to a clean, unpainted metal surface underneath the 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 sparks that could ignite gasoline in the engine compartment. After the cables have been connected, start the vehicle and allow it to run for around five minutes. Then disconnect the cables in reverse. The battery in your Saab 9-3 will be recharged as you drive. It takes a while for it to drop back down. You should purchase a second key fob, when you can. Replacing the only 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 it is lost, they'll be charged. It's expensive to add an additional key and it requires replacing the CIM or TWICE in the case of older models. It is recommended to have a second key in case of theft or other disaster and the most effective way is to purchase an additional key as quickly as you can. But don't buy a used key even it's new. Keys that are claimed as new from aftermarket sellers will not work and are almost guaranteed to fail at the critical moment. The dealer will charge you the highest dollar if you have only one working key. We can reset and reprogram the computer's EEEPROM in order for it to accept a replacement key without the need to replace the entire system. This could save you lots of money. It's also much less expensive than waiting until you lose your one key.
