Saab Key Programming
Saab cars built since 1994 use an immobilizer that relies on a set of keys. 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 using a Tech2 diagnostic tool.
The problem is that this could be very expensive. This is the reason why you should always have a spare key on hand.
saab key replacement cost is a piece of hardware equipped with an electronic chip. It sends a signal back to the car when it is inserted into the ignition. The car is able to check whether the signal is the same as the one on the key. If the signals are the same, the car will unlock itself and start. This is a great method to avoid car theft and keep your car secure from thieves.
Transponder keys could be an increasingly popular feature for cars, but they're not as secure as traditional keys made of metal. While the metal parts of a conventional key can be cut and copied the transponder is protected by an electronic chip. The chip is equipped with a unique code programmed into the car's computers to identify it.
When a Saab key fob is used, the car recognizes it and allows it to turn on. The car can only recognize the key fob if the device has a chip that is unmodified and programmed to match. If not, the car will reject the key and refuse to start.
It is essential to have an extra Saab key. This is especially true for those who live in a rural area where there are numerous car thieves. You can purchase a new key for your Saab by visiting the dealership and not paying their high cost. In most cases, you can have an original key made on the spot at a fraction of the cost of what you would pay at dealerships.
Key for Wired
Saab cars are usually provided with two keys. If you only have one, it is a good idea to get an extra key fob as soon as is possible in case you lose it, your car will require an entirely new CIM unit, and the locking cylinders 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 will require a good deal of soldering. There isn't a standard method to go about it, but you need to think about how to connect and solder each column and row. There are 22 microcontroller wires as well as pins to connect for this keyboard. It includes 5 rows and 17 column.
After the columns and rows are soldered, it's time to connect them to key switches. Solder a diode to each key switch pin. This will protect the pins from current, thus preventing them from getting shorted. A diode can only allow current to flow in one direction, and has a the black band as a visual indicator that indicates the direction current will flow.
A few of the tools that are available at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- may aid shop customers or DIY customers in certain instances program replacement keys and restore the lost immobilizer's data, Sanabria says. The tools plug into the OBD port and automatically guide the customer through the procedure, making it simpler than replacing the computer in the vehicle.
Jump-starting the battery
Most people keep a few sets of jumper cables in their trunks for emergency situations, but jumping a battery on newer cars might not be the best option. These vehicles have many computers and digital devices that communicate with each other. A voltage surge when the battery is connected another can fry the components making your car unusable.
Start the vehicle you are using and let it run for about two minutes before you connect the cables to the battery that is not working. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end to a clean unpainted metal surface under the hood of the disabled vehicle. The engine block is a great alternative. The black cable should not be connected to the negative terminal of the dead battery. This could trigger sparks, which would ignite the gasoline in the engine compartment.
Once the cables are connected the disabled vehicle and allow it to run for around five minutes before you disconnect them in reverse order. The battery in your Saab 9-3 is recharged while you drive. It takes a while for it to return to its original state. It's a good idea invest in a spare key fob as soon as you can, because replacing the only functioning one requires the installation of a brand new computer module and a special program to convince it that the lost keys aren't in the process of trying to steal the car.
Replacement case
Many Saab owners have only one key for their car and if they lose it, it's going to cost them. The reason for this is that it's not cheap to purchase a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. It's recommended to have a backup key in the event of theft or other disaster the best solution is to purchase a second key as quickly as you can. However, don't purchase a secondhand key even if it's "new." Claimed-new keys purchased from third-party sellers won't perform and are almost certain to fail in the most critical moment.
The majority of locksmiths won't be able to help if you have only one working key, and the dealer will charge for the cost of replacing the computer in your vehicle to make a new replacement. However, we can reset and re-program the computer's EEPROM to prepare it to accept an alternative key without replacing the whole system. This could save you lots of money. It's also cheaper than waiting until you lose your one key.
