Saab cars manufactured since 1994 come with an immobilizer system that is based on codes for keys. In order to add a second key, it requires a new transponder, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.
The issue is that it can be very costly. Always keep an extra set of keys at hand.
Transponder key
The transponder is a piece of key equipped with an electronic chip. This chip sends out a signal when the key is placed in 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 deter car theft and keep your vehicle safe from thieves.
Transponder keys could be a popular addition to cars, but they are not as secure as traditional metal keys. The metal part of the traditional key can easily be cut and copied, whereas transponders have an electronic chip that safeguards it. The 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 turn on. The car can only recognize the key fob if the device has an unmodified chip 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 especially important when you live in a rural area where there are many car thieves. The good part is that you can get a replacement key for your Saab without having to go to an auto dealer and pay the high prices that they charge. In most instances, you can get a new key created on-the-spot at a fraction of the price of what you would pay at a dealer.
Wired key
Saab cars are usually provided with two keys. If you have only one, you should get an additional key as quickly as you can. This is because if you lose it and the car needs an entirely new CIM and the locking cylinders replaced. This can be costly particularly for used cars.
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 will require a large amount of soldering. It's not a common way to do it, but you need to plan how to connect and solder each column and row. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller wires and pins that you need to connect.
After the rows and column are soldered together then it's time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins of the key switch from current and prevent 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 indicates the direction in which current will flow.
Some of the tools available at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- may help shop customers 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 in the vehicle.
Jumpstarting the battery
The majority of people have an assortment of tools in their trunks to jump start a car in case of emergency, but this might not be the best idea for cars with more modern technology. These vehicles have many electronic devices and computers that communicate with one another. A surge in voltage when a battery is hooked up to another could cause damage to the components and render your vehicle undriveable.
Connect the cables to the vehicle that is working. Let it run for two minutes. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to an unpainted, clean metal surface underneath the disabled car's hood. The engine block is a good option. Don't connect the black cable to the negative terminal of the dead battery because this could trigger an ignition spark that ignites the gasoline in the engine bay.
Once the cables are connected, you can begin the car and let it run for about five minutes. Then, disconnect them in reverse. The battery in your
saab key replacement near me 9-3 is recharged as you drive. It will take a while for it to return to its original state. 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 special programming to convince it that the lost keys aren't in the process of trying to steal the car.
Replacement case
saab 9-3 key owners typically only have one car key, and if that is lost, they'll be charged. The reason for this is that it's expensive to buy a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It is recommended to have a spare key in case of theft or any other catastrophe and the most effective way is to buy an extra key as early as you can. Don't purchase a used key even if it's "new." Keys that are claimed as new purchased from third-party sellers won't work and are likely to fail in the crucial moment.
The dealer will charge you top dollar if you have only one working key. We can reset and reprogram the computer's EEEPROM to make it ready to accept a replacement key without the need to replace the entire system. This can save you a significant amount of money. It's less expensive than wait until you loose the only key.
