Saab Key Programming
Saab cars that were built prior to 1994 feature an immobilizer mechanism that is based on codes for keys. A new transponder is required in order to enable the addition of an additional key, as well as special programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.
It can be costly. You should always keep a spare set of keys at hand.
Transponder key
The transponder keys are keys with an electronic chip that sends a signal to car when it is inserted into ignition. The car then checks to see whether the signal matches with the one on the key. If the signals match, the car will unlock and start. This is a great method to protect your vehicle from theft.
saab key replacement cost may be a popular addition to cars, but they are not as secure as traditional metal keys. While the metal parts of a traditional key may be cut and copied however, a transponder is secured by an electronic chip. This chip has a unique code that is programmed into the car's computers to identify it.
The car will recognize the Saab keyfob, and allow it to be turned on. The car will only recognize the key fob if it has a chip that is unmodified and has been programmed to match. If not, the car will reject the key and won't start.
It's essential to ensure that you have a spare key for your Saab. This is especially true when you live in a rural area that is home to many car thieves. You can obtain a replacement key for your Saab by going to the dealership without paying pricey costs. In most instances, you can get a new key made on-the-spot for less than half the price of what you would pay at dealerships.
Key for Wired
Saab cars are usually delivered with two keys. If you have only one, it is recommended to get an additional key as quickly as you can. This is because if the key is lost the car will require an entirely new CIM and the locking cylinders replaced. This can be costly especially for used vehicles.
The next step is to connect the wires for the column and row to the microcontroller. This is the most challenging part of the project and requires a significant deal of soldering. There's no standard way to accomplish this, but it's important to plan out how you will 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 rows and column are soldered together then it's time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins of the key switch from current and stop them from being shorted. The diode will only allow the flow of current to be in one direction, and it also has a a black band visual indicator that indicates the direction current will flow.
Sanabria states that a number of the tools sold in auto parts stores, such as the Autel MaxiIM IM608PRO and the IM508 can assist customers shopping or DIY customers to program replacement keys and restore the immobilizer's data. The tools plug into the OBD port and automatically guide the customer through the process, making it more simple than replacing the computer inside the vehicle.
Jump starting the battery
The majority of people have a set in their trunks to jump-start a vehicle in an emergency, however it might not be a good idea for newer cars. These vehicles are equipped with numerous computers and digital devices which communicate with one another. A surge in voltage when the battery is connected to another one could damage these components, rendering your car undriveable.
Connect the cables to the vehicle that is working. Allow it to run for two minutes. 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 to a clean, unpainted metal surface under the hood of the disabled car. The engine block is a great choice. The black cable is not to be connected to the negative terminal of the dead battery. This could create a spark, which would ignite gasoline in the engine compartment.
After the cables have been connected, you need to start the vehicle and let it run for approximately five minutes. Then disconnect them in reverse. The battery in your Saab 9-3 will be recharged while you drive. It will take a while for it to drop back down. You should consider purchasing another 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
Saab owners usually only have one car key, and if it is lost, they will be charged. It's costly to add the key and also requires replacing the CIM or TWICE in the case of older models. In the event of theft or any other catastrophe it is recommended to have an extra key. Even even if the key is "new" it will not function.
Most locksmiths can't help you with a single working key, and the dealer will charge high fees to replace the computer in your vehicle to make a new replacement. We can reset and reprogram the EEEPROM of your computer 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 much cheaper than wait until you lose the only key.
