Saab Key Programming
Saab cars built since about 1994 have an immobilizer system made up of coded keys. A new transponder is required in order to enable the inclusion of an additional key, as well as special programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.
It can be costly. It is recommended to always have an extra set of keys at hand.
Transponder key
The transponder key comes with an electronic chip that sends a signal to car when it is inserted into the ignition. The car then checks to see whether the signal matches the one on the key. If the signals match then the car will be able to open and start. This is a great way to protect your car from theft.
Transponder keys are a favored feature in vehicles, but it is important to know that they aren't as secure as classic keys made of metal. While the metal part of a traditional key can be cut and copied however, a transponder is secured by an electronic chip. This chip has an unique code that is programmed into the car's computer to identify it.
The car will recognize the Saab keyfob, and allow it to be turned on. However, it will only do this if your key fob is equipped with a chip that is not modified that has been programmed to match it. Otherwise, the car would reject the key and won't start.
It is crucial to have a spare Saab key. This is especially important if you reside in a rural location that has numerous car thieves. The good part is that you can obtain a replacement key for your Saab without having to go to a dealer and pay the expensive prices they ask. In most instances, you can get a brand new key made right on the spot for less than half the price of what you'd pay at a dealer.
Key for Wired
Saab cars are usually delivered with two keys. If you have only one, it is recommended to purchase an additional key fob as quickly as you can in case you lose it, your car will require a new CIM unit and the locking cylinders will have to be replaced. This can be costly, especially for used cars.
The next step is connecting the wires for columns and row to your microcontroller. This is the most difficult part of the project, and it will require a lot of soldering. There isn't a standard method to do it, but you must plan how to connect and solder each column and row. There are 22 microcontroller wires and pins that you can connect for this keyboard. It has five rows and 17 columns.
After the rows and column are soldered together, it is time to connect the key switches. To do this you must place an inverter over each pin on the key switch and solder it. This will protect the pins from current, thus preventing them from getting shorted. A diode only allows the flow of current to be in one direction, and it comes with a an indicator in black that indicates the direction in which current will flow.
Some of the tools available at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- can help customers in the shop, or even DIY customers in certain cases replace keys in the program and restore lost immobilizer data Sanabria says. The tools connect to 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
A lot of people keep an item in their trunk to jump-start their car in case of emergency, but it might not be the best option for vehicles with newer technology. These vehicles are equipped with many digital and computers that communicate with one another. A surge in voltage while the battery is connected to another can fry the components and render your vehicle undriveable.
Start the vehicle you are using and allow it to run for around two minutes before you connect the cables to the disabled one. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to a clean, unpainted metal surface under the disabled car's hood. The engine block would be an ideal choice. Do not connect the black cable to the negative terminal of the dead battery, since it could spark an ignition that ignites the gasoline in the engine bay.
After the cables have been connected, begin the car and let it run for about five minutes. Then disconnect the cables in reverse. Remember that the battery on the Saab 9-3 gets recharged during your drive, which means it will take a while to get the battery back to normal. It is a good idea to invest in a spare key fob as soon as you can, since replacing the only working one requires the installation of a new computer module and a special program to convince it that your missing keys aren't trying to steal the car.
Replacement case
Saab owners usually have only one car key, and if that is lost, they will be charged. It's expensive to purchase the key and also requires replacing the CIM or TWICE in the case of older models. In the event of theft, or any other calamity, it is best to have a spare key. Even even if the key is "new" it will not work.
please click the next webpage will charge the highest dollar if you only have one working key. We can, however, reset and reprogram the computer's EEPROM in order to prepare it to accept a new key without replacing the whole system. This can help you save money. It's also much less expensive than waiting until you lose the only key.
