saab 9-3 key Key Programming

Saab cars made since 1994 have an immobilizer system built on coded keys. To add an additional key, you need the purchase of a new transponder as well as special programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.

The issue is that this could be very costly. This is why you should always keep a spare key in your possession.

Transponder key

The transponder key is a key equipped with an electronic chip. It sends a signal back to the car when it is inserted into ignition. The car checks to see whether the signal matches the one on the key. If the signals match it will open and start. This is a great method to avoid auto theft and keep your vehicle secure from thieves.

Transponder keys are a favored feature in cars, but you should be aware that they aren't as secure as classic metal keys. The metal portion of a traditional key is easily cut and copied, whereas the transponder is protected by an electronic chip that protects it. The chip is equipped with a unique code that is encoded into the car's system to identify it.

When a Saab Ignition Key Replacement key fob is used, the car recognizes it and allows it to turn on. However, it will only do this if your key fob has a non-modified chip that has been programmed to match the original. Otherwise, the car will reject the key and refuse to start.

Wired key

Saab cars usually come with two keys when new. If you only own one, you should get an additional key as quickly as you can. This is because if the key is lost and the car is damaged, it will require a new CIM and the locking cylinders replaced. This could be expensive, especially if you are buying a used car.

The next step is connecting the row and columns wires to your microcontroller. This is the toughest aspect of the project and will require lots of soldering. There's no standard way to do this, but it is important to think about how you will route and solder the rows and columns. There are 22 microcontroller wires and pins that you can connect to this keyboard. It has 5 rows and 17 column.

After the columns and rows are soldered, it's time to connect them to the key switches. Solder a diode on each key switch pin. This will protect the pins from current, thus preventing them from being shorted. A diode allows the current to flow in a single direction, and has a an indicator in black that indicates the direction in which current will flow.

Sanabria states that a number of the tools available in auto parts stores, such as the Autel MaxiIM IMM608PRO and IM508 can assist customers shopping or DIY users to program replacement keys and restore immobilizer information. The tools connect to the OBD port and guide the user through the process, making it easier than replacing the computer in the vehicle.

Jump-starting the battery

A lot of people keep a set of jumper cables in their trunk for emergencies, but jumping a battery on modern automobiles might not be the best idea. These vehicles are equipped with digital and computer systems that communicate with each other. A voltage surge when the battery is connected to another battery could damage the components, rendering your car undriveable.

Start the vehicle you are using and allow it to run for approximately two minutes before you connect 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 to a clear, unpainted metal surface under the hood of the damaged car. The engine block is a good choice. The black cable should not be connected to the negative terminal of the dead battery. This could trigger sparks, which would ignite the gasoline that is in the engine compartment.

After the cables have been connected, you need to start the vehicle and let it run about five minutes. Then, disconnect the cables in reverse. The battery in the Saab 9-3 will charge as you drive. It will take a while for it to recharge again. You should invest in an additional key fob as soon as possible. Replacing the only one that works requires the installation and programming of a brand new computer chip.

Replacement Case

saab car keys owners often only have one car key, and if that is lost, they will be charged. The reason is that it's not cheap to buy a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, and programming. In the event of theft or any other calamity, it is best to have a spare key. However, don't purchase a secondhand key even the case that it's "new." Keys that are claimed to be new from aftermarket sellers will not work and are almost guaranteed to fail in the most critical moment.
