Saab Key Programming
Saab cars made since 1994 use an immobilizer system that is based on a set of keys. Adding an extra key requires a new transponder, as well as special programming. This is usually done at the dealer using a Tech2 diagnostic tool.
It can be costly. Always keep an extra set of keys at hand.
Transponder key
The transponder key is a key with an electronic chip that sends a signal to the car when it is inserted into ignition. The car will check to see whether the signal matches the one on the key. If the signals are in sync the car will then unlock and start. This is a fantastic way to protect your car from theft.
Transponder keys can be an extremely popular accessory for cars, but they're not as safe as traditional metal keys. While the metal part of a traditional key may be cut and copied but a transponder key is protected by an electronic chip. The chip has a unique code programmed into the car's computers 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. Otherwise, the car will reject the key and won't start.
It is vital to have a spare saab 9-3 key programming (sociable-cyclamen-fkj5mq.mystrikingly.com) key. This is especially important if you live in a rural area, where there are numerous car thieves. The good news is that it's possible to find a replacement key to your Saab without needing to visit an auto dealer and pay the high prices that they demand. In most instances, you can get a new key created on-the-spot for less than half the price of what you would pay at an auto dealer.
Wired key
saab 9-3 replacement key cars are usually delivered with two keys. If you only have one, it is an ideal idea to purchase an extra key fob as soon as you can as if you lose it, your car will require the replacement of a CIM unit, and the locking cylinders will need to be replaced. This can be costly especially for cars that are used.
The next step is connecting the wires for columns and rows to your microcontroller. This is the toughest aspect of the project and it will require lots of soldering. There's no standard way to accomplish this, however it is essential to determine the way you'll route and solder the rows and columns. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins to connect.
After the columns and rows are joined It is now time to connect the key switches. Solder a diode to each key switch pin. This will protect the key switch pins from current and prevent them from being shorted. A diode can only allow the current to flow in a single direction, and it has the black band as a visual indicator that indicates which way the current will flow.
Sanabria says that some of the tools offered in auto parts stores, including the Autel MaxiIM IM608PRO or IM508 will assist customers shopping or DIY users to program replacement keys and restore immobilizer information. The tools connect to 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 a set of jumper cables in their trunk for emergency situations, but jumping a battery on newer automobiles might not be the best idea. These vehicles are equipped with a number of computers and digital devices that communicate with one another. A surge in voltage when batteries are connected to another battery could damage the components, rendering your car undriveable.
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 of the black cable to a clean, unpainted metal surface beneath the damaged car's hood. The engine block is an excellent choice. Don't connect the black cable to the negative terminal on the dead battery, as this could trigger a spark that ignites the gasoline in the engine bay.
After the cables have been connected, start the vehicle and let it run about five minutes. Then disconnect the cables in reverse. Remember that the battery on the Saab 9-3 gets recharged when you drive, and it may take some time for the battery to come down. It's a good idea to purchase a spare key fob as soon as you can, since replacing the one that works requires the installation of a new computer module and special programming to convince it that your lost saab key keys aren't in the process of trying to steal the car.
Replacement Case
Many Saab owners only have one key for their car and if they lose it, key, it will cost them. The reason is that it's costly to replace a 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 disaster it is best to have a spare key. Even when the key is "new", it won't work.
The dealer will charge you the most expensive dollar if you have only one working key. We can reset and reprogram the computer's EEEPROM in order to get it ready to accept a replacement key without having to replace the entire system. This can save you a significant amount of money. It's cheaper to do this rather than wait until you lose the only key.
