5 Killer Quora Answers To Saab Ignition Key Replacement

Saab Key Programming

saab 9-3 key programming cars manufactured since 1994 have an immobilizer system that is based on codes for keys. The addition of a key requires the purchase of a new transponder as well as special programming. This is usually done by the dealer using a special Tech2 diagnostic tool.

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

Transponder key

The transponder key comes equipped with an electronic chip. It transmits a signal to the car when it is placed in the ignition. The car then analyzes the signal to see whether it matches the one on the key. If the signals are in sync, the car will open and start. This is a great method to safeguard your car from theft.

Transponder keys could be a popular addition to cars, but they're not as secure as traditional metal keys. The metal portion of a traditional key can easily be cut and copied, however transponders have an electronic chip that guards it. The chip is equipped with a unique code that is encoded into the car's system to identify it.

The car will recognize the Saab keyfob, and allow it to be turned on. However, it will only do this if the key fob is unmodified and has a chip that has been programmed to match it. Otherwise, the car would reject the key and refuse to start.

There is no standard method to accomplish this, but it is crucial to plan how you will route and solder the rows and columns. There are 22 microcontroller wires and pins that you can connect for this keyboard. It has 5 rows and 17 column.

After the columns and rows are soldered together after which it is time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins from current and prevent them from being shortened. A diode permits current to only flow in only one direction. It features a visual indicator with a black band that indicates the direction in which current will flow.

Sanabria states that some of the tools that are sold in auto parts stores, like the Autel MaxiIM IM608PRO or IM508, can help customers shopping or DIY users to program replacement keys and restore immobilizer information. The tools plug into the OBD port and automatically guide the user through the process, making it easier than replacing the computer inside the vehicle.

Jump-starting the battery

A lot of people keep a set of jumper cables in their trunk for emergency situations, but jumping a battery in newer vehicles may not be the best choice. These cars have a variety of digital and electronic devices that communicate with one another. A voltage spike when the battery is connected to another can fry the components making your car unusable.

Start the vehicle that is working and allow it to run for approximately 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 of the black cable to an unpainted, clean metal surface beneath the damaged car's hood--the engine block is an ideal choice. The black cable is not to be connected to the negative terminal of the dead battery. This could create sparks, which could ignite the gasoline inside the engine compartment.

Once the cables are connected, turn on the vehicle that is disabled and allow it to run for around five minutes before disconnecting the cables in reverse order.

It's a good idea purchase a spare fob as soon as you can, because replacing the one that works requires the installation of a new computer module and special programming to convince it that the lost keys are not trying to steal the car.

Replacement Case

Saab owners often only have one car key, and if that is lost, they will be charged. 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, and programming. In the event of theft, or any other disaster, it is best to have a spare key. However, don't purchase a secondhand key, even the case that it's "new." Keys that are claimed to be new from a second-hand store will not be effective and are almost guaranteed to fail in the crucial moment.

The dealer will charge the highest dollars if you only have one working key. We can, however, reset and reprogram the computer's EEPROM in order to prepare it to accept the new key without having to replace the whole system. This could save you a great deal of money. It's also a lot cheaper than waiting until you lose the only key.
