14 Common Misconceptions About Saab Ignition Key Replacement
Saab Key Programming

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

The issue is that this can be quite costly. This is why you should always have a spare key at hand.

Transponder key

The transponder can be described as a key that has an electronic chip. The chip sends a signal when the key is placed into the ignition. The car then checks the signal to determine whether it is the same as the one that is in the key. If the signals are identical, the car will unlock itself and start. This is an excellent way to protect your vehicle from theft.

Transponder keys are a common feature in vehicles, but you should be aware they are not as secure as classic metal keys. While the metal parts of a traditional key may be cut and copied the transponder is protected by an electronic chip. This chip has an unique code that is encoded into the car's system to identify it.

The car will recognize the Saab keyfob and permit it to be turned on. However, it is only able to do so if the key fob has an unmodified chip that has been programmed to match it. The car will not start in the event that the key has not been programmed to match.

It's essential to ensure that you have a spare key for your Saab. This is especially true if you reside in a rural region that has many car thieves. You can get a new key for your Saab by going to the dealership, without having to pay their high costs. You can have the replacement key on the spot at a fraction of what you would spend at dealerships.

Wired key

Saab cars are usually supplied with two keys. If you own only one, it is recommended to get an additional key as quickly as you can. This is because if it's lost the car will require an entirely new CIM and the locking cylinders replaced. This can be costly, especially if you are buying a second-hand car.

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 great deal of soldering. There is lost saab keys to accomplish this, but it is essential to determine the routes you'll use to solder the columns and rows. For this keyboard, there are 5 rows and 17 columns, which means there will be 22 microcontroller wires and pins that you need to connect.

After the columns and rows are joined after which it is time to connect the key switches. To do this, you need to place a diode on each pin of the key switch and then solder it. This will protect the pins of the key switch from current and also prevent them from being shorted. A diode lets current only flow in one direction. It has a visual indicator that is black, that shows the direction in which the current will flow.

Some of the tools offered at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- may help shop customers or even DIY customers in certain cases create replacement keys and restore lost immobilizer data, Sanabria says. The tools connect to OBD ports and help the customer through each step making the process simpler than replacing the car's computer.

Jump-starting the battery

A lot of people keep an assortment of tools in their trunks to jump-start a car in case of emergency, but it might not be the best idea for newer cars. They have numerous digital and computer systems that communicate with each other. A surge in voltage when the battery is connected another can fry the components making your car unusable.

Connect the cables to the vehicle operating. Allow it to run for two minutes. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to a clean, unpainted metal surface under the disabled car's hood--the engine block is an excellent choice. Don't connect the black cable to the negative terminal of the dead battery because it could ignite an ignition source that ignites gasoline in the engine bay.

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, so it can take a while for the battery to come back down again. You should purchase another key fob when you can. Replacing the only 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 car and if they lose it, the cost will be. The reason for this is that it's expensive to add a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It is best to have a second key in case 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-new purchased from third-party sellers won't be effective and are almost guaranteed to fail at the critical moment.

Most locksmiths can't help you if you have only one working key and the dealer will charge you top dollar to replace the computer in your car to create a replacement. We can, however, reset and re-program your computer's EEPROM to prepare it 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 your sole key.
