Saab Key Programmingsaab key fob cars manufactured since 1994 feature an immobilizer system that relies on keys that are coded. To add an additional key, you need the purchase of a new transponder as well as special programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.
The issue is that it can be extremely expensive. This is why it is important to always keep a spare key in your possession.
Transponder key
The transponder can be described as a key that has an electronic chip. The chip transmits a signal when the key is put into the ignition. The car then checks the signal to determine whether it is the same as the one in the key. If both signals match, the car will unlock itself and start. This is an excellent way to guard your car against theft.
Transponder keys can be an extremely popular accessory for cars, but they're not as secure as traditional keys made of metal. The metal part of the traditional keys can be easily cut or copied, while the transponder is protected by an electronic chip that protects it. The chip is a unique code that is programmed into a car's computer order to identify it.
The car will recognize the
lost saab key keyfob and permit it to be turned on. The car will only recognize the key fob if the device has an unmodified chip and has been programmed to match. The car will not start when the key isn't programmed to match.
It is crucial to have an extra
saab key replacement cost key. This is particularly important when you live in a rural region where there are a lot of car thieves. You can get a brand new key for your
saab key programming by visiting the dealership, without having to pay their high costs. You can have a replacement key created on the spot at a fraction of what you would pay at an auto dealer.
Wired key
Saab cars are usually delivered with two keys. If you only have one, it is a good idea to get an extra key fob as quickly as you can as if you lose it, the car will require a new CIM unit and the locking cylinders will have to be replaced. This can be costly especially if purchasing a used car.
The next step is to connect the wires for columns and rows to your microcontroller. This is the toughest part of the project and will require a lot of soldering. There's no standard way to do this, but it is crucial to plan the way you'll 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, it is time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins from current and prevent them from being shorted. The diode will only allow current to flow in one direction, and has a a black band visual indicator that indicates the direction current will flow.
Sanabria says that some of the tools offered in auto parts stores, such as the Autel MaxiIM IM608PRO and IM508 will assist customers who are shopping or DIY customers to program replacement keys and restore data from the immobilizer. The tools connect to the OBD port and guide the user through the procedure, making it much easier 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 the event of an emergency, but this might not be the best idea for vehicles that are newer. These vehicles have many digital and computer systems that communicate with one another. A voltage surge when the battery is connected to another one could cause damage to the parts, rendering your car undriveable.
Connect the cables to the vehicle 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 unpainted metal surface underneath the hood of the disabled vehicle. The engine block is an excellent option. Don't connect the black cable to the negative terminal on the dead battery because it could spark an ignition source that ignites gasoline in the engine bay.
After the cables have been connected, you need to begin the car and let it run for approximately five minutes. Then disconnect the cables in reverse. Be aware that the battery in the Saab 9-3 will be charged when you drive, so it will take a while for the battery to go back down again. You should purchase a second key fob, as soon as possible. The replacement of the one that works requires the installation and programming of a new computer chip.
Replacement case
Many
saab key replacement cost owners only have one key for their car and if they lose that the cost will be. The reason is that it's not inexpensive to replace a key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It is recommended to have a second key in the event of theft or any other catastrophe, and the best way is to purchase an additional key as soon as you can. Even it's "new" it will not function.
The dealer will charge you the most expensive dollar if you have only one working key. We can reset and reprogram the computer's EEEPROM in order to get it ready to accept a replacement key without the need to replace the entire system. That can help you save money. It's much cheaper rather than wait until you lose the only key.
