10 Myths Your Boss Is Spreading Regarding Saab Ignition Key Replacement

Saab Key Programming

Saab cars manufactured since 1994 feature an immobilizer mechanism based on coded keys. In order to add a second key, it requires 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 can be very expensive. This is why it is important to always have a spare key at hand.

Transponder key

The transponder key is a key with an electronic chip that sends a signal to car when it is placed in the ignition. The car then 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 great method to prevent auto theft and keep your vehicle secure from thieves.

Transponder keys are an increasingly popular feature in automobiles, however you must be aware that they're not as secure as traditional keys made of metal. The metal component of a traditional key can be easily cut and copied, whereas the transponder is protected by an electronic chip that guards it. The chip contains a unique code that's programmed into a car's computers in order to identify it.

The car will recognize the saab keys keyfob and permit it to turn on. But, it's only able to do this if the key fob is equipped with a chip that is not modified that has been programmed to match the original. In the absence of that, the car will reject the key and won't start.

The next step is connecting the wires for columns and row to your microcontroller. This is the most challenging part of the project and will require a great deal of soldering. It's not a common way to go about it, but you need to plan how to route 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.

Once the rows and columns are soldered, it's the time to connect them to the key switches. Solder a diode on each key switch pin. This will shield the pins that are used for key switches from current and also prevent them from being shorted. A diode only allows the current to flow in a single direction, and it also has a an indicator in black that indicates the direction current will flow.

Sanabria says that some of the tools that are sold in auto parts stores, including the Autel MaxiIM IMM608PRO and IM508 will assist shoppers or DIY customers to program replacement keys and restore immobilizer data. The tools plug into the OBD port and guide the customer through the procedure, making it much easier than replacing the computer in the vehicle.

Jumpstarting the battery

Most people keep a set of jumper cables in their trunk in case of emergency however, jumping a battery on newer vehicles may not be the best idea. These vehicles are equipped with many electronic devices and computers that communicate with one another. A surge of voltage when the battery is connected to another battery could damage the components and render your vehicle unusable.

Start the vehicle you are using and let it run for about two minutes before you connect the cables to the non-working one. Attach the red clip to the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end to a clean unpainted metal surface beneath the hood of the affected car. The engine block is an excellent option. The black cable is not to be connected to the negative terminal of the dead battery. This could cause sparks, which would ignite the gasoline in the engine compartment.

Once the cables are connected, you should begin the car and let it run for approximately five minutes. Then disconnect them in reverse. The battery in your Saab 9-3 will recharge as you drive. It will take some time for it to return to its original state. It's a good idea to invest in a spare key fob as soon as you can, since replacing the sole working one requires the installation of a new computer module and special programming to convince it that the lost keys aren't attempting to steal the car.

Replacement Case

The dealer will charge you the highest dollar for only one working key. However, we can reset and reprogram the computer's EEPROM in order to prepare it to accept an alternative key without replacing the entire system. This can help you save a significant amount of money. It's also cheaper than waiting until you lose your one key.
