Saab Key Programming

Saab cars built since about 1994 come with an immobilizer system made up of coded keys. Adding an extra key requires an entirely new transponder and programming. This is usually done at the dealer, using a specially-designed Tech2 diagnostic tool.

This can be expensive. Always keep a spare set of keys in your possession.

Transponder key

The transponder key comes equipped with an electronic chip. It sends a signal to the car when it is inserted into the ignition. The car then checks the signal to see whether it matches the one on the key. If the signals match, the car will unlock and start. This is a fantastic way to protect your vehicle from theft.

Transponder keys are an increasingly popular feature for cars, but they are not as secure as traditional keys made of metal. The metal portion of a traditional key can be easily cut or copied, while transponders are protected by an electronic chip that protects it. This chip contains an individual code that is programmed into the car's computer 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 the fob is equipped with a chip that is not modified that has been programmed to match. The car won't start in the event that the key has not been programmed to match.

It is vital to have an extra Saab key. This is particularly important when you live in a rural region that has many car thieves. You can purchase a new key for your Saab by visiting the dealership and not paying their expensive costs. You can get a replacement saab car keys key created on the spot for less than half what you would spend at a dealership.

If you only have one, it's a good idea to get an additional key fob as soon as you can in case you lose it, the car will require an entirely new CIM unit, and the locking cylinders have to be replaced. This can be costly, especially if you are buying a used car key copy.

The next step is to connect the wires of the column and row to the microcontroller. This is the most difficult part of the project, and it will require lots of soldering. There is no standardized way to accomplish this, however it's important to plan out the way you'll route and solder the columns and rows. There are 22 microcontroller wires and pins to connect for this keyboard. It has 5 rows and 17 columns.

After the columns and rows are joined, it is time to connect the key switches. To do this you must place a diode across each pin of the key switch and solder it. This will protect the pins from current, thus preventing them from being shortened. A diode permits current to only flow in only one direction. It features a visual indicator that is black, that indicates the direction in which current will flow.

Sanabria says that some of the tools sold in auto parts stores, like the Autel MaxiIM IMM608PRO and IM508 will assist shoppers or DIY customers to program replacement saab car keys keys and restore data from the immobilizer. The tools plug into the OBD port and automatically guide the customer through the process, making it more simple than replacing the computer inside the vehicle.

Jump starting the battery

A lot of people keep a set of jumper cables in their trunk to use in an emergency however, jumping a battery on modern vehicles may not be the most efficient option. These vehicles are equipped with numerous digital and computer systems that communicate with one another. A voltage surge when the battery is connected another can fry the components making your car inoperable.

Connect the cables to the vehicle that is operating. Let it run for two minutes. 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 of the black cable to a clean, unpainted metal surface underneath the vehicle's hood. An engine block is an excellent choice. Don't connect the black cable to the negative terminal on the dead battery because this could trigger a spark that ignites the gasoline in the engine bay.

After the cables have been connected, you can begin the car and let it run for about five minutes. Then, disconnect them in reverse. Be aware that the battery in your Saab 9-3 is recharged when you drive, and it may take some time to get the battery back to its original level. You should consider purchasing a second key fob, when you can. Replacing the one that works requires the installation and programming of a new computer chip.

Saab owners often only have one car key, and if that is lost, they will be charged. The reason for this 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. It is best to have a backup key in the event of theft or any other catastrophe and the best option is to purchase an additional key as soon as you can. However, don't purchase a secondhand key, even if it's "new." Keys that are claimed-new from aftermarket sellers will not perform and are almost certain to fail in the crucial moment.

The dealer will charge you the most expensive dollar for only one working key. We can reset and reprogram the EEEPROM of your computer to get it ready to accept a new key without the need to replace the entire system. This can help you save a significant amount of money. It's also much less expensive than waiting until you lose the only key.
