Saab Key Programming Saab cars manufactured since 1994 utilize an immobilizer that relies on keys that are coded. The addition of a key requires a new transponder and special programming. This is usually done at the dealer using a special Tech2 diagnostic tool. It can be costly. It is always advisable to keep an extra set of keys available. Transponder key The transponder is a key with an electronic chip. The chip transmits a signal when the key is put into the ignition. The car then examines the signal to see if it matches the one in the key. If the signals match, the car will unlock itself and begin. This is a great way to protect your car from theft. Transponder keys can be an increasingly popular feature for cars, but they're not as safe as traditional keys made of metal. While the metal portion of a conventional key can be cut and copied, a transponder is protected by an electronic chip. This chip contains an unique code that is programmed into a car's computer in order to identify it. The car will recognize the Saab keyfob, and allow it to turn on. The car can only recognize the key fob if it is equipped with a chip that is unmodified and has been programmed to match. The car will not start when the key isn't programmed to match. It is important to have a spare Saab key. This is especially important especially if you reside in a rural location where there are many car thieves. You can get a brand new key for your Saab by visiting the dealership without paying expensive prices. saab car key can have an original key made on the spot for less than half the cost you would pay at a dealership. Key for Wired Saab cars are usually supplied with two keys. If you only have one, it is recommended to get an extra key as soon as you can. This is because if you lose it and the car needs an entirely new CIM and the locking cylinders replaced. This can be expensive, 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 way to accomplish this, but it is essential to determine the route you'll take and solder the columns and rows. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins to connect. After the rows and column are joined, it is time to connect the key switches. Solder a diode to each key switch pin. This will shield the pins that are used for key switches from current and prevent them from being shorted. A diode only allows the current to flow in a single direction, and has a a black band visual indicator that shows the direction in which current will flow. Sanabria states that a number of the tools available in auto parts stores, including the Autel MaxiIM IM608PRO and the IM508 can assist customers shopping or DIY customers to program replacement keys and restore data from the immobilizer. The tools connect to the OBD port and guide the customer through the process, making it easier than replacing the computer inside the vehicle. Jump-starting the battery A lot of people keep a set of jumper cables in their trunk to use in an emergency, but jumping a battery in newer vehicles may not be the most efficient option. These cars have a variety of computers and digital devices that communicate with one another. A surge of voltage when batteries are connected to another could cause damage to 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 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 under the hood of your disabled vehicle. The engine block is an excellent choice. The black cable should not be connected to the negative terminal of the dead battery. This could create sparks that could ignite the gasoline that is in the engine compartment. Once the cables are connected, start the vehicle that is disabled and let it run for approximately five minutes before you disconnect the cables in reverse order. Be aware that the battery in the Saab 9-3 gets recharged when you drive, and it could take a while for the battery to come back to its original level. It is a good idea to purchase a spare key fob as soon as you can, since replacing the only working one requires the installation of a brand new computer module and special programming to convince the system that your lost keys are not trying to steal the car. Replacement Case Many Saab owners only have one key for their vehicle and if they lose that key, it will cost them. The reason for this is that it's costly to add a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. In the event of theft, or any other catastrophe it is advisable to have a spare key. Don't purchase a used key, even if it's “new.” Claimed-new keys from sellers selling aftermarket keys won't work and are likely to fail at the crucial moment. Most locksmiths cannot help you when you only have one working key and the dealer will charge top dollar to replace the computer in your car to make a new replacement. However, we can reset and re-program your computer's EEPROM to accept an alternative key without replacing the whole system. This can help you save a significant amount of money. It's also much less expensive than waiting until you lose your sole key.
