Saab Key Programming

saab ignition key cars manufactured from 1994 have an immobilizer system that relies on coded keys. Adding an extra key requires an entirely new transponder and programming. This is usually done at the dealer, using a specially-designed Tech2 diagnostic tool.

It can be costly. This is why it is important to always have a spare key on hand.

Transponder key

The transponder keys are keys with an electronic chip that sends a signal back to the car when it is inserted into ignition. The car checks to see whether the signal matches with the one on the key. If the signals match it will open and start. This is a fantastic way to guard your car against theft.

Transponder keys are a popular addition to cars, but they are not as secure as traditional keys made of metal. The metal component of a traditional keys can be easily cut and copied, whereas transponders have an electronic chip that protects it. This chip has an individual code that is programmed into the car's computer to identify it.

The car will recognize the saab key fob programming keyfob and permit it to turn on. However, it is only able to do this if the 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 has not been programmed to match.

It is essential to ensure that you have an extra key for your Saab. This is particularly important if you live in a rural area where there are numerous car thieves. The good thing is that you can find a replacement Saab car keys key to your Saab without having to go to a dealer and pay the high costs that they ask.

If you only have one, it's recommended to purchase an additional key fob as soon as you can as if you lose it, the car will require an entirely new CIM unit and the locking cylinders will need to be replaced. This can be costly, especially if you are buying a used car.

The next step is to wire the wires for the column and row to the microcontroller. This is the most difficult part of the project and it will require lots of soldering. There isn't a standard way to accomplish this, however it is important to think about the route you'll take and solder the rows and columns. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller wires and pins to connect.

After the rows and column are joined It is now time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins from current, thus preventing them from being shortened. A diode lets current only flow in only one direction. It features a visual indicator that is black, that indicates the direction in which current will flow.

Sanabria says that a few of the tools offered in auto parts stores, including the Autel MaxiIM IM608PRO and the IM508 will assist customers who are shopping or DIY customers to program replacement keys and restore data from the immobilizer. The tools plug into the OBD port and guide the customer through the process, making it easier than replacing the computer in the vehicle.

Jump-starting the battery

Most people keep a few sets of jumper cables in their trunks for emergencies however, jumping a battery on modern vehicles may not be the best idea. These vehicles are equipped with many digital and computer systems that communicate with each other. A voltage spike when a battery is hooked up to another can fry these components and render your car unable how to open a saab 93 without a key drive.

Start the vehicle you are using and allow it to run for around two minutes before connecting the cables to the battery that is not working. Attach the red clip to the positive terminal on the battery that is good (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 a good choice. The black cable is not to be connected to the negative terminal of the dead battery. This could create sparks, which could ignite gasoline in the engine compartment.

Once the cables are connected, you can start the vehicle that is disabled and let it run for approximately five minutes before disconnecting the cables in reverse order. Be aware that the battery of your Saab 9-3 is charged during your drive, which means it could take a while for the battery to go back down again. It is recommended to purchase an additional key fob as soon as possible. Replacing the original one that works requires the installation and programming of a new computer chip.

Replacement case

Many Saab owners only have one key for their car and if they lose it, they'll be charged. The reason is that it's costly to add a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It is best to have a spare key in case of theft or any other catastrophe the best solution is to purchase a second key as soon as you can. Even it's "new", it will not function.

Most locksmiths can't help you if you have only one working key, and the dealer will charge high fees to replace the computer in your vehicle to make a new replacement. We can reset and reprogram the computer's EEEPROM in order to make it ready to accept a replacement key without having to replace the entire system. This could save you a significant amount of money. It's less expensive than wait until you lose the only key.
