the dealer using a speciallydesigned Tech2 diagnostic tool This can be expensive This is the reason why you should always have a spare key on hand Transponder key The transponder keys are keys equipped with an electronic chip It sends a signal back to the car when it is put into the ignition The car then checks to see whether the signal matches with the one on the key If the signals match it will open itself and start This is a great way to stop car theft and keep your vehicle safe from thieves Transponder keys are a popular feature in automobiles however it is important to know that they are not as secure as traditional keys made of metal While the metal part of a conventional key can be cut and copied however a transponder is secured by an electronic chip The chip is a unique code that is inserted into a cars computer 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 an unmodified chip and has been programmed to match If not the car will reject the key and refuse to start Its important to make sure that you have an extra key for your Saab This is particularly important for those who live in a rural area that is home to many car thieves The good news is that its possible to find a replacement key to your Saab without needing to visit an auto dealer and pay the hefty prices that they ask In most cases you can have a brand new key made right on the spot for less than half the cost of what you would pay at an auto dealer Key for Wired Saab cars usually come with two keys when theyre new If you only have one it is best to acquire an extra key fob as soon as is possible in case you lose it your car will require an entirely new CIM unit and the locking cylinders have to be replaced This could be expensive particularly if you are buying a used car The next step is connecting the row and columns wires to your microcontroller This is the most challenging part of the project and will require a good deal of soldering Theres no standard way to do it however you should think about how to connect and solder each column and row There are 22 microcontroller wires as well as pins to connect to this keyboard It includes 5 rows and 17 columns After the columns and rows are soldered together it is time to connect the key switches Solder a diode on each key switch pin This will shield the pins that are used for key switches from current and also prevent them from being shorted A diode can only allow the flow of current to be in one direction and has a the black band as a visual indicator that indicates the direction in which current will flow Sanabria says that some of the tools available in auto parts stores including the Autel MaxiIM IMM608PRO and IM508 can help shoppers or DIY customers to program replacement keys and restore the immobilizers data how to get a saab replacement key into the OBD port and guide the user through the process making it more simple than replacing the computer inside the vehicle Jumpstarting the battery Most people keep a set of jumper cables in their trunk in case of emergency however jumping a battery for newer vehicles might not be the best option These vehicles are equipped with numerous digital and computers that communicate with one another A voltage spike when the battery is connected to another battery could fry these components and leave your vehicle unable to drive Start the vehicle that is working and allow it to run for around two minutes before connecting the cables to the one that is disabled Attach the red clip on the positive terminal of the battery thats good It will read POS or Attach the other end of the black cable to an unpainted clean metal surface underneath the disabled cars hood The engine block would be a good option Do not connect the black cable to the negative terminal on the dead battery because it could spark an ignition spark that ignites the gasoline in the engine bay Once the cables are connected start the car and let it run about five minutes Then disconnect them in reverse Be aware that the battery of the Saab 93 gets recharged during your drive which means it will take a while for the battery to come down Its a good idea to purchase 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 your lost keys are not trying to steal the car Replacement case Saab owners typically only have one car key and if that is lost they will be charged Its expensive to buy a key and requires replacing the CIM or TWICE for older models In the event of theft or any other catastrophe it is recommended to have a spare key Even its new it will not work Most locksmiths arent able to help if you have only one working key and the dealer will charge for the cost of replacing the computer in your vehicle to make a new replacement However we can reset and reprogram the computers EEPROM in order to prepare it to accept a new key without replacing the entire system That can help you save money Its also cheaper than waiting until you lose the only key
