Saab Key Programming Saab cars built since about 1994 have an immobilizer feature made up of coded keys. A new transponder is required to allow the addition of an extra key, and special programming. This is usually done at the dealer using a Tech2 diagnostic tool. The issue is that this can be very expensive. This is why it is important to always have a spare key available. 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 in the ignition. The car then analyzes the signal to determine whether it matches that of the key. If the signals match the car will then open and start. This is a great method to deter car theft and keep your car safe from thieves. Transponder keys are a popular feature in cars, but it is important to know that they're not as secure as classic metal keys. The metal component of the traditional key can easily be cut or copied, while the transponder is protected by an electronic chip that protects it. The chip contains a unique code which is programmed into the car's computer in order to identify it. The car will recognize the Saab keyfob, and allow 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. The car will not start if the key is not programmed to match. It is essential to have a spare Saab key. This is particularly important for those who live in a rural area, where there are a lot of car burglars. The good part is that you can find a new key for your Saab without needing to visit an auto dealership and pay the hefty prices they ask. In saab ignition key , you can get a new key created on-the-spot for less than half the price of what you'd pay at the dealer. Key for Wired Saab cars typically come with two keys when they are new. If you have only one, it's a good idea to get an extra key fob as soon as is possible since if you lose it, your car will require the replacement of a CIM unit and the locking cylinders have to be replaced. This could be expensive particularly if you are purchasing a used vehicle. The next step is to connect the row and column wires to the microcontroller. This is the toughest component of the project and it will require a lot of soldering. There isn't a standard way to do this, but it is important to think about the way you'll route and solder the rows and columns. There are 22 microcontroller wires as well as pins to connect for this keyboard. It has five rows and 17 columns. After the columns and rows are joined then it's time to connect the key switches. To do this you must place an inverter over each key switch pin and then solder it. This will shield the pins on the key switch from current and keep them from being shorted. A diode lets current only flow in one direction. It is equipped with a visible indicator that is black, that shows the direction in which the current will flow. Sanabria states that a number of the tools sold in auto parts stores, including the Autel MaxiIM IMM608PRO and IM508 are able to assist customers who are shopping or DIY users to program replacement keys and restore the immobilizer's data. The tools connect to OBD ports and guide the user through each step and make the process more straightforward than replacing the vehicle's computer. Jump-starting the battery Most people keep a few sets of jumper cables in their trunk in case of emergency, but jumping a battery in newer vehicles may not be the best idea. These cars have a variety of digital and computer systems that communicate with one another. A voltage surge while a battery is hooked up to another one could damage these components and render your car unable to drive. Start the working vehicle and let it run for about two minutes before you connect the cables to the disabled one. Attach the red clip to the positive terminal of the battery that is good (it will have POS or + on it). Attach the other end to a clean, unpainted metal surface underneath the hood of the disabled car. The engine block is a good choice. Don't connect the black cable to the negative terminal of the dead battery, since it could ignite a spark that ignites the gasoline in the engine bay. After the cables have been connected, start the car and allow it to run for around five minutes. Then, disconnect them in reverse. Be aware that the battery in the Saab 9-3 gets recharged while you drive, so it could take a while for the battery to go back to its original level. It is recommended to purchase an additional key fob as soon as you can. The replacement of the one that works requires the installation and programming of a new computer chip. Replacement Case Many Saab owners only have one key for their car and if they lose that the cost will be. The reason for this is that it's expensive to add a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft, or any other calamity it is advisable to have an extra key. Even if the key is new it will not work. The dealer will charge you top dollars if you only have one working key. We can reset and reprogram the computer's EEEPROM for it to accept a new key without replacing the entire system. This could help you save a significant amount of money. It's much cheaper instead of waiting until you lose the only key.
