14 Questions You Shouldn't Be Insecure To Ask About Saab Ignition…

Saab Key Programming

Saab cars produced since 1994 use an immobilizer system based on keys that are coded. A new transponder is required for addition of an additional key, as well as special programming. This is usually done by the dealer using a special Tech2 diagnostic tool.

The issue is that it can be extremely expensive. You should always keep an extra set of keys in your possession.

Transponder key

The transponder key comes with an electronic chip that sends a signal back to the car when it is inserted into ignition. The car will check to see if the signal matches the one on the key. If the signals match the car will be able to unlock itself and begin. This is a fantastic way to protect your car from theft.

Transponder keys are an increasingly popular feature in automobiles, however you should be aware that they are not as secure as classic keys made of metal. The metal portion of a traditional keys can be easily cut or copied, while the transponder is protected by an electronic chip that safeguards it. The chip is equipped with a unique code encoded into the car's system to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. The car can only recognize the key fob if the device has an unmodified chip and has been programmed to match. The car will not start when the key isn't programmed to match.

It is crucial to have a spare Saab key. This is particularly true especially if you live in a rural location that has many car thieves. You can get a brand new key for your Saab by going to the dealership and not paying their expensive cost. In most cases, you can have a new key created on-the-spot at a fraction of the cost of what you'd pay at an auto dealer.

Wired key

Saab cars usually come with two keys upon purchase. If you only have one, it's best to acquire an extra key fob as quickly as you can as if you lose it the car will require the replacement of a CIM unit and the locking cylinders will need to be replaced. This can be expensive especially for cars that are used.

The next step is connecting the row and columns wires to your microcontroller. This is the most challenging part of the project and will require a large amount of soldering. There's no standard way to do this, but it is crucial to plan the route you'll take and solder the rows and columns. There are 22 microcontroller wires as well as pins to connect for this keyboard. It has 5 rows and 17 column.

Once the rows and columns are soldered, it's time to connect them to key switches. Solder a diode to each key switch pin. This will shield the pins that are used for key switches from current and keep them from being shorted. A diode allows current to only flow in only one direction. It is equipped with a visible indicator with a black band that indicates which direction current will flow.

Some of the tools you can find at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- can help customers in the shop, or even DIY users in some cases create replacement keys and restore the lost immobilizer's data, Sanabria says. The tools plug into the OBD port and Saab Key Programming guide the customer through the procedure, making it simpler than replacing the computer inside the vehicle.

Jump-starting the battery

Most people keep an assortment of tools in their trunk to start a vehicle in an emergency, but it may not be a good option for vehicles with newer technology. These vehicles are equipped with a number of electronic devices and computers that communicate with one another. A voltage spike when the battery is connected to another could cause damage to these components and leave your car unable to drive.

Start the working vehicle and let it run for about two minutes before you connect the cables to the battery that is not working. Attach the red clip to the positive terminal of the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clean unpainted metal surface under the hood of the damaged car. The engine block is an excellent option. The black cable should not be connected to the negative terminal of the dead battery. This could cause sparks that could ignite gasoline in the engine compartment.

Once the cables are connected, you can start the vehicle that is disabled and let it run for about five minutes before you disconnect the cables in reverse order. Keep in mind that the battery on the Saab 9-3 will be charged when you drive, and it will take a while to get the battery back to its original level. It's a good idea buy a spare key fob as soon as you can, since replacing the one that works requires the installation of a brand new computer module and a special program to convince it that your missing keys aren't attempting to steal the car.

Replacement case

Many saab 9-3 key fob programming owners have only one key for their vehicle and if they lose that key, it will cost them. The reason is that it's expensive to purchase a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft, or any other catastrophe it is recommended to have a spare key. But don't buy a used key even the case that it's "new." Keys that are claimed as new purchased from third-party sellers won't work and are likely to fail at the critical moment.

The dealer will charge the highest dollars if you only have one working key. However, we can reset and re-program the computer's EEPROM to accept a new key without replacing the entire system. This can save you a significant amount of money. It's also cheaper than waiting until you lose the only key.
