Saab Key Programming
Saab cars that were built prior to 1994 feature an immobilizer mechanism made up of coded keys. A new transponder is required in order to enable the addition of a second key, and special programming. This is usually done at the dealer using a Tech2 diagnostic tool.
It can be costly. You should always keep a spare set of keys at hand.
Transponder key
The transponder key is a piece of hardware with an electronic chip that sends a signal to car when it is inserted into ignition. The car then examines the signal to see whether it is the same as that of the key. If the signals are in sync then the car will be able to unlock and start. This is a great way to safeguard your car from theft.
Transponder keys are a common feature in automobiles, but you should be aware they aren't as secure as traditional metal keys. The metal portion of a traditional keys can be easily cut and copied, however a transponder has an electronic chip which protects it. The chip is equipped with a unique code that is encoded into the car's system to identify it.
The car will recognize the Saab keyfob and permit it to turn on. However, it can only do this if your key fob has a non-modified chip that has been programmed to match it. The car won't start in the event that the key is not programmed to match.
It is vital to have a spare Saab key. This is especially true for those who live in a rural region where there are a lot of car thieves. You can get a new key for your Saab by going to the dealership, without having to pay their high costs. You can get the replacement key on the spot for less than half of the cost you would pay at a dealership.
Wired key
Saab cars are typically delivered with two keys. If you own only one, you should get an additional key as quickly as you can. This is because if you lose it and the car is damaged, it will require a new CIM and the locking cylinders replaced. This can be costly particularly if you are purchasing a used vehicle.
saab key replacement near me is to connect the row and column wires to the microcontroller. This is the most tedious part of the project and will require lots of soldering. There isn't a standard way to accomplish this, but it is crucial to plan how you will route and solder the columns and rows. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller pins and wires to connect.
After the columns and rows are soldered, it's the time to connect them to the key switches. Solder a diode on each key switch pin. This will shield the pins from current, thus preventing them from being shortened. A diode only allows current to flow in one direction, and it also has a an indicator of black color that shows the direction in which current will flow.
Sanabria says that a few of the tools sold in auto parts stores, including the Autel MaxiIM IM608PRO and IM508, can help shoppers or DIY customers to program replacement keys and restore immobilizer information. The tools connect to the OBD port and automatically guide the user through the procedure, making it simpler than replacing the computer inside the vehicle.
Jump starting the battery
Most people keep an assortment of tools in their trunks to jump-start their vehicle in the event of an emergency, but this might not be a good idea for cars with more modern technology. These vehicles are equipped with many electronic devices and computers that communicate with one another. A voltage spike when the battery is connected to another one could damage these components and render your car unable to drive.
Connect the cables to the vehicle that is working. Allow it to run for two minutes. Attach the red clip on the positive terminal of the good battery. (It will say "POS" or "+".) Attach the other end to a clean and unpainted metal surface under the hood of the disabled vehicle. The engine block is an excellent choice. Don't connect the black cable to the negative terminal on the dead battery because it could ignite an ignition spark that ignites the gasoline in the engine bay.
Once the cables are connected, you can start the vehicle and let it run about five minutes. Then disconnect the cables in reverse. Keep in mind that the battery on the Saab 9-3 gets recharged when you drive, so it can take a while for the battery to come back down again. It's a good idea to purchase a spare key fob as soon as you can, since replacing the only functioning one requires the installation of a brand new computer module and a special program to convince it that your missing 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. It's expensive to purchase the key and also requires replacing the CIM or TWICE for older models. It is best to have a second key in case of theft or any other catastrophe and the best option is to purchase an extra key as early as you can. However, don't purchase a secondhand key even if it's "new." Claimed-new keys from aftermarket sellers will not work and are likely to fail in the crucial moment.
The dealer will charge the highest dollar if you only have one working key. We can reset and reprogram the computer's EEEPROM in order to get it ready to accept a new key without the need to replace the entire system. This can save you a great deal of money. It's also much less expensive than waiting until you lose your sole key.
