saab Ignition key cars produced since 1994 utilize an immobilizer system that relies on keys that are coded. The addition of a key requires an entirely new transponder and programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

It can be costly. This is the reason why you should always have a spare key at hand.

Transponder key

The transponder keys are keys equipped with an electronic chip. It transmits a signal to the car when it is inserted into ignition. The car then examines the signal to determine whether it matches the one that is in the key. If the signals match then the car will be able to open and start. This is a great method to stop car theft and keep your car secure from thieves.

Transponder keys can be an extremely popular accessory for automobiles, but they are not as secure as traditional metal keys. While the metal portion of a traditional key may be cut and copied but a transponder key is protected by an electronic chip. The chip has an individual code that is programmed into the car's computers to identify it.

The car will recognize the Saab keyfob and permit it to turn on. The car will only recognize the key fob if it is equipped with an unmodified chip and has been programmed to match. The car won't start if the key is not programmed to match.

It is vital to have an extra Saab key. This is especially important especially if you live in a rural region that has numerous car thieves.

This is because if the key is lost and the car is damaged, it will require an entirely new CIM and Saab Ignition Key the locking cylinders replaced. This could be expensive, especially if you are purchasing a used vehicle.

The next step is connecting the wires of columns and row to your microcontroller. This is the most difficult component of the project and it will require a lot of soldering. There is no standard method to accomplish this, however it is important to think about the routes you'll use to solder the rows and columns. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins that you need to connect.

After the rows and column are joined It is now time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins from current, and prevent them from being shorted. A diode lets current only flow in one direction. It has a visual indicator with a black band that shows which way current will flow.

Some of the tools you can find at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- can assist customers at the shop or DIY customers in some cases create replacement keys and restore lost immobilizer information, Sanabria says. The tools connect to OBD ports and help the customer through each step which makes the process much easier than replacing the vehicle's computer.

Jump starting the battery

Most people keep a few sets of jumper cables in their trunks for emergency situations, but jumping a battery for newer vehicles may not be the best idea. These vehicles are equipped with numerous electronic devices and computers that communicate with each other. A surge in voltage when the battery is connected to another could cause damage to these components and render your vehicle unable to drive.

Start the vehicle you are using and allow it to run for approximately two minutes before connecting the cables to the one that is disabled. Attach the red clip to the positive terminal on 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 under the disabled car's hood--the engine block is a good choice. Do not connect the black cable to the negative terminal of the dead battery, since it could ignite a spark that ignites the gasoline in the engine bay.

Once the cables are connected, turn on the vehicle that has been disabled and allow it to run for around five minutes before you disconnect them in reverse order. Keep in mind that the battery on the saab key fob replacement 9-3 gets recharged during your drive, which means it may take some time for the battery to go back down again. It's a good idea invest in a spare key fob as soon as you can, since replacing the only functioning one requires the installation of a brand new computer module and special programming to convince it that the lost keys are not trying to steal the car.

Replacement Case

saab key fob owners usually only have one car key, and if it is lost, they will be charged. The reason is that it's costly to add 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. Don't purchase a used key even the case that it's "new." Keys that are claimed to be new from a second-hand store will not perform and are almost certain to fail at the crucial moment.

Most locksmiths aren't able to help with a single working key, and the dealer will charge you high fees to replace the computer in your car for a replacement. However, we can reset and reprogram the computer's EEPROM to prepare it to accept a new key without replacing the entire system. This could save you a significant amount of money. It's also much less expensive than waiting until you lose your one key.
