Saab Key Programming Saab cars built since about 1994 feature an immobilizer mechanism that is based on codes for keys A new transponder is required for addition of a second key as well as special programming This is usually done by the dealer using the Tech2 diagnostic tool The issue is that this can be quite costly Always keep an extra set of keys in your possession Transponder key The transponder can be described as a key with an electronic chip This chip sends a signal when the key is inserted into the ignition The car then checks the signal to see if it matches the one in the key If the signals are in sync it will unlock and begin This is a great way to avoid car theft and keep your car secure from thieves Transponder keys are a favored feature in cars but you should be aware that they are not as secure as classic metal keys The metal portion of a traditional key is easily cut and copied whereas a transponder has an electronic chip which protects it The chip has a unique code embedded into the cars computer to identify it The car will recognize the Saab keyfob and permit it to be turned on The car will only recognize the key fob if the device has a chip that is unmodified and has been programmed to match Otherwise the car will reject the key and wont start It is essential to have an extra Saab key This is especially important for those who live in a rural region that has numerous car thieves The good part is that you can obtain a replacement key for your Saab without having to go to an auto dealer and pay the expensive prices they ask In most instances you can get an original key made on the spot at a fraction of the cost youd pay at an auto dealer Wired key Saab cars are usually supplied with two keys If you have only one it is best to acquire an extra key fob as soon as you can in case you lose it the car will require a new CIM unit and the locking cylinders will have to be replaced This can be expensive especially for cars that are used The next step is to wire the wires of the column and row to the microcontroller This is the most difficult part of the project and requires a significant amount of soldering Its not a common way to do it however you should consider how you will connect and solder each column and row There are 22 microcontroller wires as well as pins to connect for this keyboard It has 5 rows and 17 columns Once the rows and columns are soldered its time to connect them to the key switches To do this put a diode on each pin on the key switch and solder it This will shield the pins from current thus preventing them from being shorted A diode only allows current to flow in one direction and it has the black band as a visual indicator that shows the direction in which current will flow Sanabria states that some of the tools that are sold in auto parts stores like the Autel MaxiIM IM608PRO or IM508 can help customers shopping or DIY users to program replacement keys and restore the immobilizers data The tools connect to OBD ports and help the customer through each step making the process simpler than replacing the cars computer Jumpstarting the battery Most people keep a set of jumper cables in their trunks to use in an emergency however jumping a battery on modern vehicles might not be the best choice These vehicles are equipped with numerous digital and computer systems that communicate with one another A voltage surge when a battery is connected to another one could cause damage to the parts rendering your car undriveable Start the working vehicle and let it run for about two minutes before connecting the cables to the battery that is not working Attach the red clip to the positive terminal of the battery thats good It will say POS or Attach the other end of the black cable to a clean unpainted metal surface underneath the cars hoodthe engine block is an ideal choice The black cable is not to be connected to the negative terminal of the dead battery This could result in sparks which would ignite the gasoline that is in the engine compartment After the cables have been connected you should start the vehicle and allow it to run for around five minutes Then disconnect them in reverse Keep in mind that the battery on the Saab 93 will be charged when you drive so it may take some time for the battery to come back to its original level Its a good idea purchase a spare fob as soon as you can because replacing the sole working one requires the installation of a brand new computer module and a special program to convince it that the lost keys arent in the process of trying to steal the car Replacement case Saab owners often only have one car key and if it is lost they will be charged The reason for this is that its costly to purchase a new key and this involves replacing the CIM Column Integration Module or TWICE on older models plus programming Its best to have a backup key in case of theft or other disaster and the best option is to purchase a second key as soon as you are able to Even if G28 is new it wont work The dealer will charge the highest dollar for only one working key We can reset and reprogram the computers EEEPROM for it to accept a replacement key without having to replace the entire system This can help you save a significant amount of money Its also cheaper than waiting until you lose your only key
