saab replacement key Key Programming

Saab cars made since 1994 come with an immobilizer system based on coded keys. Adding an extra key requires a new transponder and special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

It can be costly. This is the reason why you should always have a spare key available.

Transponder key

The transponder is a key equipped with an electronic chip. This chip sends out a signal when the key is put in the ignition. The car then checks the signal to see whether it is identical to the one on the key. If the signals are the same the car will then unlock itself and start. This is a great way to stop auto theft and keep your car secure from thieves.

Transponder keys are a favored feature in automobiles, but you must be aware that they're not as secure as traditional metal keys. While the metal parts of a traditional key may be cut and copied, a transponder is protected by an electronic chip. The chip has a unique code that is inserted into a car's computers in order to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. However, it can only do this if your key fob is equipped with a chip that is not modified that has been programmed to match. The car will not start if the key is not programmed to match.

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 large deal of soldering. It's not a common way to do it, however, you should plan how to route and connect each column and row. For this keyboard, there are five rows and 17 columns. This means there will be 22 microcontroller pins and wires to connect.

After the columns and rows are soldered, it's time to connect them to key switches. Solder a diode to each key switch pin. This will protect the pins from current, and prevent them from being cut off. The diode will only allow current to flow in one direction, and it has an indicator of black color that indicates the direction in which current will flow.

Sanabria says that a few of the tools sold in auto parts stores, such as the Autel MaxiIM IM608PRO or IM508 are able to assist shoppers or DIY users to program replacement keys and restore the immobilizer's data. The tools connect to the OBD port and guide the user through the procedure, making it much easier than replacing the computer in the vehicle.

Jump-starting the battery

Most people keep an assortment of tools in their trunks to jump start a car in case of emergency, but this might not be a good idea for newer cars. These cars are equipped with a variety of computers and digital devices which communicate with each other. A voltage spike when the battery is connected another can fry the components and render your vehicle unusable.

Attach the other end of the black cable to an unpainted, clean metal surface beneath the damaged car's hood--the engine block is an ideal choice. The black cable is not to be connected to the negative terminal of the dead battery. This could trigger a spark, which would ignite gasoline in the engine compartment.

Once the cables are connected, turn on the vehicle that has been disabled and allow it to run for around five minutes before disconnecting the cables in reverse order.

It's a good idea to purchase a spare fob as soon as you can, because replacing the sole working one requires the installation of a brand new computer module and special programming to convince the system that your lost keys are not trying to steal the car.

Replacement saab 9-3 key Case

Many Saab owners only have one key for their vehicle and if they lose it, key, it will cost them. The reason for this is that it's not cheap to add a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. In the event of theft or any other catastrophe, it is best to have an extra key. Even it's "new" it will not function.

The dealer will charge you top dollar for only one working key. We can reset and reprogram the computer's EEEPROM in order to get it ready to accept a new key without having to replace the entire system. This could save you a significant amount of money. It's also a lot cheaper than waiting until you lose your one key.
