Saab Key Programming

Saab cars manufactured since 1994 utilize an immobilizer that relies on key codes. In order to add a second key, it requires a new transponder and special programming. This is usually done at the dealer using a special Tech2 diagnostic tool.

Transponder key

The transponder key comes equipped with an electronic chip. It sends a signal to car when it is put into the ignition. The car will check to see whether the signal matches with the one on the key. If the signals are the same the car will then unlock itself and begin. This is a great way to protect your car from theft.

Transponder keys are a popular feature in cars, but it is important to know that they are not as secure as classic keys made of metal. The metal part of the traditional keys can be easily cut and copied, whereas transponders have an electronic chip that safeguards it. This chip contains a unique code embedded into the car's computer to identify it.

The car will recognize the Saab keyfob and permit it to turn on. However, it is only able to do so if the key fob has a non-modified chip that has been programmed to match it. The car will not start if the key is not programmed to match.

The next step is to connect the row and columns wires to your microcontroller. This is the most tedious part of the project, and will require lots of soldering. There is no standardized way to do this, but it is important to think about the routes you'll use to solder the columns and rows. There are 22 microcontroller wires and pins that you can connect to this keyboard. It has five rows and 17 columns.

After the columns and rows are soldered together, it is time to connect the key switches. To do this you must place a diode on each pin of the key switch and then solder it. This will shield the pins from current and prevent them from being shortened. A diode allows current to only flow in one direction. It features a visual indicator of a black line that indicates which direction current will flow.

Sanabria states that a number of the tools available in auto parts stores, such as the Autel MaxiIM IM608PRO or IM508 are able to assist customers who are shopping or DIY users to program replacement keys and restore immobilizer information. The tools plug into the OBD port and automatically guide the user through the process, making it more simple than replacing the computer in the vehicle.

Jump-starting the battery

Most people keep a few sets of jumper cables in their trunk for emergencies however, jumping a battery for newer cars might not be the best option.

Attach the red clip to the positive terminal of the battery that's good. (It will say "POS" or "+".) Attach the other end to a clean, unpainted metal surface beneath the hood of the affected vehicle. The engine block is a great choice. Don't connect the black cable to the negative terminal of the dead battery, as it could ignite an ignition that ignites the gasoline in the engine bay.

Once the cables are connected, you need to start the car and let it run for approximately five minutes. Then, disconnect them in reverse. The battery in the saab ignition key replacement 9-3 will charge as you drive. It may take a while it to recharge again. It is a good idea to invest in a spare key fob as soon as you can, because replacing the sole working one requires the installation of a new computer module and a special program to convince it that the lost keys aren't attempting to steal the car.

Replacement case

Saab owners often only have one car key, and if it is lost, they will be charged. The reason for this is that it's not inexpensive to buy a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It's best to have a backup key in case of theft or any other catastrophe and the most effective way is to purchase a second key as early as you can. Even it's "new" it will not work.

Most locksmiths can't help you in the event that you only have one working key, and the dealer will charge high prices to replace the computer in your vehicle to make a new replacement saab car keys. However, we can reset and re-program your computer's EEPROM in order to prepare it to accept a new key without replacing the whole system. This could save you a great deal of money.
