5 Killer Quora Answers To Saab Ignition Key Replacement

saab car key Key Programming

Saab cars manufactured since 1994 feature an immobilizer mechanism based on coded keys. A new transponder is required in order to enable the addition of a second key, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

The issue is that this could be very costly. This is why it is important to always have a spare key at hand.

Transponder key

The transponder can be described as a key that is equipped with an electronic chip. The chip transmits a signal when the key is inserted in the ignition. The car is able to check whether the signal is the same as the one on the key. If the signals match the car will be able to unlock itself and begin. This is a great method to protect your car from theft.

Transponder keys are a common feature in automobiles, but you should be aware that they are not as secure as traditional metal keys. The metal portion of a traditional key is easily cut and copied, whereas a transponder has an electronic chip which protects it. This chip has an unique code that is programmed into the car's computers to identify it.

When a Saab key fob is used the car recognizes it and allows it to turn on. But, it's only able to do this if the key fob has a non-modified chip that has been programmed to match. In the absence of that, the car will reject the key and won't start.

It's not a common way to do it, however, you should consider how you will connect and solder each column and row. There are 22 microcontroller pins and wires to connect for this keyboard. It includes 5 rows and 17 columns.

After the rows and column are soldered together then it's time to connect the key switches. To do this, put an inverter over each key switch pin and solder it. This will protect the pins of the key switch from current and stop them from being shorted. The diode allows current to only flow in only one direction. It is equipped with a visible indicator, a black band, that indicates the direction in which current will flow.

Some of the tools offered at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- may help customers in the shop, or even DIY customers in some cases create replacement keys and restore lost immobilizer information, Sanabria says. The tools plug into the OBD port and automatically guide the user through the process, making it more simple than replacing the computer inside the vehicle.

Jump-starting the battery

Most people keep a set of jumper cables in their trunks to use in an emergency however, jumping a battery in newer automobiles might not be the best option. These vehicles have many digital and electronic devices that communicate with one another. A surge in voltage when a battery is hooked up to another battery could fry these components, rendering your vehicle unable to drive.

Start the working vehicle and let it run for about 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 an unpainted, clean metal surface beneath the damaged car's hood. The engine block would be a good choice. Don't connect the black cable to the negative terminal of the dead battery, since this could trigger an ignition source that ignites gasoline in the engine bay.

Once the cables are connected, you should start the vehicle and let it run for about five minutes. Then disconnect the cables in reverse. The battery in the saab replacement keys 9-3 will charge as you drive. It will take a while for it to return to its original state. It is a good idea to purchase a spare key fob as soon as you can, since replacing the sole working one requires the installation of a new computer module and special programming to convince it that your lost keys are not trying to steal the car.

Replacement case

Saab owners often only have one car key, and if it is lost, they will be charged. It's costly to add a key and requires replacing the CIM or TWICE for older models. In the event of theft or any other catastrophe it is advisable to have an extra key. But don't buy a used key even if it's "new." Keys that are claimed to be new from sellers selling aftermarket keys won't work and are almost guaranteed to fail in the crucial moment.

The dealer will charge you the highest dollar for only one working key. However, we can reset and re-program your computer's EEPROM to prepare it to accept an alternative key without replacing the entire system. This can save you lots of money. It's also less expensive than waiting until you lose your sole key.
