Saab Key Programming

Saab cars manufactured since 1994 come with an immobilizer system based on coded keys. The addition of a key requires a new transponder, as well as special programming. This is usually done at the dealer using a Tech2 diagnostic tool.

The problem is that this could be very expensive. It is always advisable to keep a spare set of keys in your possession.

Transponder key

The transponder key is a piece of hardware with an electronic chip that sends a signal to car when it is put into the ignition. The car checks to see whether the signal matches with the one on the key. If the signals match it will unlock and begin. This is a great way to prevent auto theft and keep your vehicle safe from thieves.

Transponder keys are an increasingly popular feature in automobiles, however it is important to know that they are not as secure as classic metal keys. The metal component of a traditional key can be easily cut and copied, whereas transponders are protected by an electronic chip that guards it. This chip has 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 this if the key fob has an unmodified chip that has been programmed to match it. The car won't start when the key isn't programmed to match.

This can be expensive, especially for used cars.

The next step is to connect the column and row wires to the microcontroller. This is the most tedious part of the project and will require a lot of soldering. It's not a standard way to go about it, but you need to plan how to route and solder each column and row. There are 22 microcontroller wires as well as pins to connect for this keyboard. It has 5 rows and 17 columns.

After the columns and rows are soldered, it's time to connect them to key switches. Solder a diode on each key switch pin. This will protect the pins from current, and prevent them from being cut off. The diode allows current to only flow in only one direction. It is equipped with a visible indicator of a black line that indicates which direction current will flow.

Sanabria says that some of the tools that are sold in auto parts stores, including the Autel MaxiIM IM608PRO or IM508 can assist customers shopping or DIY users to program replacement keys and restore the immobilizer's data. The tools connect to the OBD port and automatically guide the customer through the procedure, making it simpler than replacing the computer in the vehicle.

Jumpstarting the battery

The majority of people have a set of jumper cables in their trunk for emergencies however, jumping a battery on modern automobiles might not be the best choice. These vehicles are equipped with many digital and computers that communicate with one another.

Attach the red clip on the positive terminal of the good battery. (It will read "POS" or "+".) Attach the other end to a clear, unpainted metal surface beneath the hood of the affected car. The engine block is a good choice. Do not connect the black cable to the negative terminal of the dead battery, since it could spark an ignition that ignites the gasoline in the engine bay.

Once the cables are connected, turn on the vehicle that is disabled and let it run for about five minutes before disconnecting them in reverse order. The battery in your saab Ignition Key replacement 9-3 will recharge as you drive. It may take a while it to return to its original state. It is recommended to purchase another key fob as soon as you can. Replacing the one that works requires the installation and programming of a new computer chip.

Replacement case

Many Saab owners have only one key for their car and if they lose it, key, it will cost them. It's expensive to buy keys and will require replacing the CIM or TWICE in the case of older models. In the event of theft or any other disaster it is advisable to have a spare key. Don't purchase a used key, even it's "new." Claimed-new keys from aftermarket sellers will not be effective and are almost guaranteed to fail at the crucial moment.

The dealer will charge you the most expensive dollar for only one working key. We can, however, reset and reprogram the computer's EEPROM to prepare it to accept the new key without having to replace the entire system. This could save you a significant amount of money. It's also much less expensive than waiting until you lose your sole key.
