Saab Key ProgrammingSaab cars that were built prior to 1994 have an immobilizer feature built on coded keys. A new transponder is required in order to enable the addition of a second key, and special programming. This is usually done at the dealer using a Tech2 diagnostic tool.The problem is that this could be quite costly. It is recommended to always have a spare set of keys available.Transponder keyThe transponder is a piece of key that is equipped with an electronic chip. The chip transmits a signal when the key is placed in the ignition. The car is able to check if the signal matches the one on the key. If both signals match it will open itself and begin. This is a great way to stop auto theft and keep your vehicle secure from thieves.Transponder keys are a common feature in cars, but you should be aware they are not as secure as classic keys made of metal. The metal component of a traditional keys can be easily cut and copied, however transponders have an electronic chip that safeguards it. This chip has a unique code that is embedded into the car’s computer to identify it.The car will recognize the Saab keyfob and permit it to turn on. The car can only recognize the key fob if it is equipped with an unmodified chip and has been 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 especially important especially if you reside in a rural region where there are many car thieves. saab 93 key programming can get a brand new key for your Saab by visiting the dealership without paying their high prices. You can have a replacement key made on the spot for less than half the cost you would spend at a dealership.Wired keySaab cars are typically delivered with two keys. If you have only one, you should get an extra key as soon as you can. This is because if it’s lost and the car is damaged, it will require a new CIM and the locking cylinders replaced. This can be expensive especially for used vehicles.The next step is to connect the wires for columns and rows to your microcontroller. This is the most difficult part of the project and will require a good amount of soldering. It’s not a standard way to go about it, however, you should determine how to connect and solder each column and row. There are 22 microcontroller pins and wires to connect to this keyboard. It has five rows and 17 column.After the rows and column are joined then it’s time to connect the key switches. To do this you must place a diode across each key switch pin and solder it. This will protect the pins from current, preventing them from being shortened. 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 says that a few of the tools available in auto parts stores, like the Autel MaxiIM IM608PRO and the IM508 can assist shoppers or DIY users to program replacement keys and restore immobilizer data. The tools connect to OBD ports and help the customer through each step and make the process more straightforward than replacing the car’s computer.Jump-starting the batteryA lot of people keep the set in their trunks to jump-start a car in case of emergency, however it might not be the best idea for vehicles that are newer. These vehicles are equipped with numerous electronic devices and computers that communicate with each other. A surge in voltage while the battery is connected to another could cause damage to the components and render your car undriveable.Start the working vehicle and allow it to run for around two minutes before connecting the cables to the non-working one. Attach the red clip on the positive terminal of the battery that is good. (It will say “POS” or “+”.) Attach the other end to a clear, unpainted metal surface beneath the hood of the damaged car. The engine block is an excellent option. Don’t connect the black cable to the negative terminal on the dead battery because it could spark a spark that ignites the gasoline in the engine bay.After the cables have been connected, start the car and let it run about five minutes. Then, disconnect them in reverse. Be aware that the battery in the Saab 9-3 gets recharged when you drive, so it can take a while for the battery to go back down again. It is a good idea to buy a spare key fob as soon as you can, because replacing the only functioning one requires the installation of a new computer module and special programming to convince it that the lost keys aren’t in the process of trying to steal the car.Replacement caseSaab owners usually have only one car key, and if that is lost, they will be charged. It’s expensive to buy the key and also requires replacing the CIM or TWICE for older models. It’s best to have a spare key in the event of theft or any other catastrophe the best solution is to purchase an additional key as early as you can. But don’t buy a used key, even when 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.Most locksmiths can’t help you if you have only one working key and the dealer will charge high fees to replace the computer in your car for a replacement. We can reset and reprogram the computer’s EEEPROM to make it ready to accept a replacement key without having to replace the entire system. This could save you a significant amount of money. It’s more affordable rather than wait until you lose the only key.
