Saab Key Programming

Saab cars made since 1994 come with an immobilizer system based on coded keys. A new transponder is required in order to enable the inclusion of an additional key, and special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

It can be costly. This is why it is important to always keep a spare key in your possession.

Transponder key

The transponder key comes equipped with an electronic chip. It transmits a signal to the car when it is inserted into the ignition. The car then examines the signal to determine if it matches the one on the key. If the signals match it will open itself and begin. This is a fantastic way to guard your car against theft.

Transponder keys are a favored feature in automobiles, but you should be aware they are not as secure as traditional keys made of metal. The metal component of the traditional keys can be easily copied and cut, but a transponder has an electronic chip which protects it. This chip contains an unique code that is programmed into a car's computer order to identify it.

The car will recognize the Saab keyfob, and allow it to turn on. However, it is only able to do this if the fob has an unmodified chip that has been programmed to match the original. Otherwise, the car would reject the key and refuse to start.

The next step is to wire the wires for the column and row to the microcontroller. This is the toughest part of the project, and it will require a lot of soldering. There's no standard way to do this, but it is important to think about the way you'll route and solder the columns and rows. There are 22 microcontroller pins and wires to connect to this keyboard. It has 5 rows and 17 column.

After the columns and rows are soldered together, it is time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins from current, preventing them from getting shorted. A diode allows current to only flow in only one direction. It comes with a visual indicator, a black band, that indicates the direction in which current will flow.

Some of the tools offered at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- can assist customers at the shop or DIY users in some cases program replacement keys and restore lost immobilizer data Sanabria says. The tools plug into the OBD port and 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 emergency situations, how to open a saab 93 Without a key but jumping a battery on modern cars might not be the best option.

The engine block is a good option. The black cable should not be connected to the negative terminal of the dead battery. This could result in a spark, which would ignite the gasoline in the engine compartment.

After the cables have been connected, begin the car and let it run about five minutes. Then, disconnect them in reverse. The battery in the Saab 9-3 will charge as you drive. It will take some time for it to fall back. It's a good idea to buy a spare key fob as soon as you can, because replacing the only working one requires the installation of a brand new computer module and special programming to convince it that your lost keys aren't in the process of trying to steal the car.

Replacement case

Many Saab owners only have one key for their car and if they lose it, the cost will be. The reason for this is that it's costly to add a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. In the event of theft, or other catastrophe it is recommended to have a spare key. Don't buy a secondhand key even the case that it's "new."
