Saab Key Programming
Saab cars made since 1994 have an immobilizer system made up of coded keys. In order to add a second key, it requires an entirely new transponder and programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.
It can be costly. It is recommended to always have an extra set of keys on hand.
Transponder key
The transponder keys are keys equipped with an electronic chip. It sends a signal to car when it is put into the ignition. The car then analyzes the signal to see if it matches that of the key. If both signals match, the car will unlock itself and begin. This is a great method to guard your car against theft.
Transponder keys are a popular feature in cars, but it is important to know that they are not as secure as traditional keys made of metal. While the metal portion of a conventional key can be cut and copied but a transponder key is protected by an electronic chip. The chip contains a unique code that is inserted into a car's computer in order 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 has a chip that is unmodified and has been programmed to match. Otherwise, the car would reject the key and won't start.
It is essential to have a spare Saab key. This is particularly important especially if you reside in a rural region where there are a lot of car burglars. The good news is that you can find a new key for your Saab without needing to visit a dealership and pay the expensive prices that they charge. You can have a replacement key created on the spot at a fraction of what you would pay at a dealership.
Key for Wired
Saab cars usually come with two keys when they are new. If you have only one, it's recommended to purchase an extra key fob as soon as possible since if you lose it, the car will require a new CIM unit, and the locking cylinders have to be replaced. This can be costly particularly if you are buying a used car.
The next step is connecting 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. There is no standardized way to do this, but it is important to think about the way you'll route and solder the rows and columns. For this keyboard, there are five rows and 17 columns. This means there will be 22 microcontroller pins and wires to connect.
After the columns and rows are joined It is now time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins from current, and prevent them from getting shorted. A diode lets current only flow in one direction. It comes with a visual indicator of a black line that indicates the direction in which current will flow.
Some of the tools available at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- can aid shop customers or DIY customers in certain instances program replacement keys and restore lost immobilizer information, Sanabria says. The tools connect to the OBD port and automatically guide the user through the process, making it more simple than replacing the computer in the vehicle.
Jump-starting the battery
The majority of people have the set in their trunks to jump-start a car in an emergency, but it might not be a good idea for cars with more modern technology. These cars are equipped with a variety of computers and digital devices which communicate with each other. A surge in voltage when the battery is connected to another battery could fry these components, rendering your car unable to drive.
Start the working vehicle and allow it to run for approximately two minutes before you connect the cables to the non-working one. Attach the red clip on the positive terminal of the battery that's good. (It will say "POS" or "+".) Attach the other end to a clean, unpainted metal surface under the hood of the damaged car. The engine block is an excellent choice. The black cable should not be connected to the negative terminal of the dead battery. replacement key for saab 93 could trigger sparks, which would ignite gasoline in the engine compartment.
Once the cables are connected, you need to begin the car and let it run for about five minutes. Then, disconnect them in reverse. The battery in your Saab 9-3 is recharged as you drive. It takes a while for it to drop back down. You should purchase a second key fob, as soon as you can. Replacing the only one that works requires the installation and programming of a brand new computer chip.
Replacement Case
Many Saab owners have only one key for their vehicle and if they lose it, they'll be charged. It's expensive to add keys and will require replacing the CIM or TWICE for older models. It's best to have a backup key in case of theft or other disaster and the most effective way is to purchase an additional key as early as you can. Even when the key is "new", it will not function.
The dealer will charge you top dollar if you only have one working key. We can reset and reprogram the EEEPROM of your computer to be able to accept a replacement key without having to replace the entire system. This could save you a great deal of money. It's more affordable instead of waiting until you lose your only key.
