20 Resources That Will Make You Better At Saab Ignition Key Replacement

Saab cars produced since 1994 utilize an immobilizer system that relies on keys that are coded. Adding an extra key requires a new transponder, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

The issue is that it can be very expensive. Always keep an extra set of keys in your possession.

Transponder key

The transponder keys are keys with an electronic chip that transmits a signal to the car when it is inserted into ignition. The car will then check the signal to determine whether it is the same as the one on the key. If the signals are in sync then the car will be able to open and start. This is a great method to guard your car against theft.

Transponder keys can be a popular addition to cars, but they are not as secure as traditional keys made of metal. While the metal component of a conventional key can be cut and copied but a transponder key is protected by an electronic chip. This chip has a unique code embedded into the car's computer to identify it.

The car will recognize the saab keys keyfob and allow it to turn on. However, it is only able to do this if your key fob is equipped with a chip that is not modified that has been programmed to match it. The car won't start when the key isn't programmed to match.

It is important to have a spare Saab key. This is especially important for those who live in a rural region that has numerous car thieves. You can get a brand new key for your Saab by visiting the dealership, without having to pay their expensive cost. In the majority of instances, you can get an original key made on the spot for less than half the cost you'd pay at dealerships.

Key for Wired

Saab cars usually come with two keys upon purchase. If you own only one, it is recommended to get an additional key as soon 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 can be costly particularly for used cars.

The next step is to connect the column and row wires to the microcontroller. This is the most difficult part of the project and will require a good deal of soldering. It's not a common way to go about it, but you must consider how you will connect and solder each column and row. There are 22 microcontroller wires and pins to connect to this keyboard. It has five rows and 17 column.

After the columns and rows are soldered, it's time to connect them to the key switches. Solder a diode to each key switch pin. This will protect the key switch pins from current and prevent them from being shorted. A diode can only allow current to flow in one direction, and it has a black band visual indicator that indicates the direction current will flow.

Some of the tools available at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- may aid shop customers or DIY customers in some cases program replacement keys and restore lost immobilizer information, Saab centre Milton keynes Sanabria says. The tools plug into OBD ports and guide the user through each step making the process simpler than replacing the car's computer.

Jump-starting the battery

Most people keep the set in their trunks to start a vehicle in an emergency, but this might not be the best idea for vehicles that are newer. These vehicles are equipped with a number of digital and computer systems that communicate with one another. A surge of voltage when the battery is connected another can fry the components making your car unusable.

Start the working vehicle and allow it to run for around two minutes before you connect the cables to the one that is disabled. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end to a clear, unpainted metal surface underneath the hood of the damaged car. The engine block is a good choice. The black cable is not to be connected to the negative terminal of the dead battery. This could cause a spark, which would ignite gasoline in the engine compartment.

Once the cables are connected, you need to start 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 while you drive, so it could take a while for the battery to come back to its original level. It is recommended to purchase another key fob as soon as you can. The replacement of the one that works requires the installation and programming of a brand new computer chip.

Replacement Case

Many Saab owners only have one key for their vehicle and if they lose it, the cost will be. The reason is that it's not inexpensive to replace a key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. It's recommended to have a second key in the event of theft or any other catastrophe and the most effective way is to purchase an additional key as quickly as you can. Don't buy a secondhand key, even the case that it's "new." Keys that are claimed to be new from sellers selling aftermarket keys won't perform and are almost certain to fail at the critical moment.

The dealer will charge you the highest dollar if you have only one working key. However, we can reset and re-program your computer's EEPROM in order to prepare it to accept the new key, without replacing the whole system. This could save you a great deal of money. It's cheaper to do this than waiting until you loose the only key.
