Saab Key Programming Saab cars built since 1994 use an immobilizer system that relies on key codes. To add an additional key, you need a new transponder and special programming. This is usually done by the dealer using the Tech2 diagnostic tool. The problem is that this could be extremely expensive. This is why you should always have a spare key available. Transponder key The transponder is a piece of key equipped with an electronic chip. This chip sends out a signal when the key is put into the ignition. The car then checks to see if the signal matches the one on the key. If the signals match the car will be able to unlock itself and begin. This is a great method to guard your car against theft. Transponder keys are a popular feature in vehicles, but you must be aware that they're not as secure as classic keys made of metal. The metal component of the traditional key is easily cut and copied, however transponders have an electronic chip that guards it. This chip contains an unique code that's programmed into the 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 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 in the event that the key is not programmed to match. It is vital to have a spare Saab key. This is particularly important especially if you reside in a rural area where there are a lot of car thieves. You can purchase a new key for your Saab by going to the dealership, without having to pay their expensive prices. In most cases, you can have a new key made on-the-spot for less than half the cost you would pay at a dealer. Wired key Saab cars are usually delivered with two keys. If you have only one, it's best to acquire an additional key fob as soon as you can as if you lose it the car will require an entirely new CIM unit, and the locking cylinders have to be replaced. This can be costly particularly for used cars. The next step is to connect the wires for columns and row to your microcontroller. This is the toughest aspect of the project and it will require a lot of soldering. It's not a standard way to go about it, but you must determine how to route and connect each column and row. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller pins and wires to connect. Once the rows and columns are soldered, it's the time to connect them to the key switches. To do this, put a diode over each key switch pin and then solder it. This will protect the pins on the key switch from current and prevent them from being shorted. A diode can only allow the flow of current to be in one direction, and has a an indicator of black color that indicates which way the current will flow. Sanabria states that some of the tools that are sold in auto parts stores, including the Autel MaxiIM IM608PRO or IM508 are able to assist customers shopping or DIY users to program replacement keys and restore immobilizer data. The tools plug into the OBD port and automatically guide the customer through the procedure, making it much easier than replacing the computer inside the vehicle. Jump starting the battery The majority of people have an assortment of tools in their trunk to start a car in an emergency, but this might not be the best option for vehicles with newer technology. They have numerous computers and digital devices that communicate with one another. saab key code while the battery is connected to another one could damage the components and render your vehicle undriveable. Start the vehicle you are using and allow it to run for around two minutes before you connect the cables to the non-working one. Attach the red clip to the positive terminal on the good battery (it will have “POS” or “+” on it). Attach the other end of the black cable to an unpainted, clean metal surface underneath the car's hood. The engine block would be a good option. The black cable should not be connected to the negative terminal of the dead battery. This could result in sparks, which could ignite the gasoline that is in the engine compartment. Once the cables are connected the vehicle that has been disabled and let it run for about five minutes before disconnecting the cables in reverse order. Remember that the battery on the Saab 9-3 will be charged during your drive, which means it could take a while for the battery to go back down again. You should invest in an additional key fob when you can. The replacement of the 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. The reason for this is that it's costly to buy a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. It is best to have a backup key in the event of theft or any other catastrophe and the most effective way is to purchase a second key as soon as you can. Don't buy a secondhand key, even if it's “new.” Keys that are claimed to be new purchased from third-party sellers won't perform and are almost certain to fail at the critical moment. The dealer will charge you the highest dollar for only one working key. However, we can reset and reprogram the computer's EEPROM to accept the new key, without replacing the entire system. This can save you a lot of money. It's also much less expensive than waiting until you lose your sole key.
