saab 9-3 key fob programming Key Programming

Saab cars manufactured since 1994 come with an immobilizer system that is based on codes for 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 special Tech2 diagnostic tool.

It can be costly. You should always keep an extra set of keys at hand.

Transponder key

The transponder is a piece of key that has an electronic chip. This chip sends a signal when the key is inserted into the ignition. The car will then check the signal to see whether it is identical to the one on the key. If the signals are the same the car will then unlock itself and start. This is an excellent way to protect your car from theft.

Transponder keys are a common feature in cars, but you should be aware that they are not as secure as traditional metal keys. While the metal part of a traditional key could be cut and copied however, a transponder is secured by an electronic chip. This chip contains a unique code embedded into the car's computer to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. The car can only recognize the key fob if the device has a chip that is unmodified and has been programmed to match. If not, the car will refuse to accept the key and will not start.

It is essential to have an extra Saab key. This is especially important especially if you live in a rural region that has many car thieves. The good thing is that you can find a replacement key to your Saab without having to go to an auto dealer and pay the expensive prices that they charge. You can have a replacement key created on the spot for less than half of the price you'd spend at an auto dealer.

Key for Wired

Saab cars are typically delivered with two keys. If you have only one, you should get an extra key as soon as you can. This is because if it's lost and the car is damaged, it will require a new CIM and the locking cylinders replaced. This can be expensive, especially for used cars.

The next step is to wire the row and column wires to the microcontroller. This is the most tedious component of the project and it will require lots of soldering. There is no standard method to do this, but it is essential to determine 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 five rows and 17 column.

After the columns and rows are soldered together after which it is time to connect the key switches. To do this, place a diode on each key switch pin and solder it. This will shield the pins from current, preventing them from getting shorted. The diode will only allow current to flow in one direction, and it comes with a an indicator of black color that indicates which way the current will flow.

Some of the tools offered at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- can aid shop customers or DIY users in some cases programme replacement keys and recover the lost immobilizer's data, Sanabria says. The tools connect to OBD ports and help the customer through each step which makes the process much easier than replacing the car's computer.

Jump-starting the battery

The majority of people have a set of jumper cables in their trunks for emergencies, but jumping a battery on newer cars might not be the best choice. These vehicles are equipped with a number of digital and electronic devices that communicate with each other. A surge in voltage when the battery is connected to another can fry the components making your car inoperable.

Connect the cables to the vehicle that is operating. Let it run for two minutes. 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 to a clean, unpainted metal surface under the hood of the disabled car. The engine block is an excellent choice. The black cable is not to be connected to the negative terminal of the dead battery. This could cause sparks that could ignite the gasoline that is in the engine compartment.

After the cables have been connected, start the vehicle and let it run for about five minutes. Then, disconnect the cables in reverse. The battery in your Saab 9-3 is recharged as you drive. It will take some time for it to recharge again. It's a good idea purchase a spare fob as soon as you can, since replacing the only working one requires the installation of a brand new computer module and a special program to convince the system that your lost keys aren't in the process of trying to steal the car.

Replacement case

Saab spare key owners typically only have one car key, and if it is lost, they'll be charged. The reason is that it's not inexpensive to replace a key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. It's best to have a backup key in the event of theft or other disaster the best solution is to purchase a second key as early as you can. However, don't purchase a secondhand key, even the case that it's "new." Claimed-new keys from aftermarket sellers will not work and are likely to fail in the crucial moment.

Most locksmiths can't help you with a single working key and the dealer will charge high prices to replace the computer in your car to make a replacement. However, we can 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 can help you save money. It's cheaper to do this than wait until you lose your only key.
