saab 9-3 key not accepted contact service Key Programming

saab keys cars produced since 1994 utilize an immobilizer system that relies on key codes. A new transponder is required for the addition of a second key, as well as special programming. This is usually done at the dealer using a special Tech2 diagnostic tool.

The issue is that it can be quite costly. You should always keep a spare set of keys in your possession.

Transponder key

The transponder key is a key with an electronic chip that transmits a signal to the car when it is inserted into the ignition. The car then analyzes the signal to see whether it matches the one that is in the key. If the signals are in sync it will open and start. This is a great way to deter auto theft and keep your vehicle secure from thieves.

Transponder keys may be an increasingly popular feature for cars, but they are not as secure as traditional keys made of metal. The metal portion of a traditional keys can be easily cut or copied, while a transponder has an electronic chip that guards it. This chip contains a 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. However, it can only do so if the key fob is equipped with a chip that is not modified that has been programmed to match the original. Otherwise, the car would refuse to accept the key and will not start.

This could be expensive especially if buying a used car.

The next step is to connect the wires for columns and row to your microcontroller. This is the most difficult part of the project and will require a great amount of soldering. There's no standard way to accomplish this, however it is crucial to plan the way you'll route and solder the rows and columns. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller wires and pins that you need to connect.

After the rows and column are soldered together then it's time how to program saab 9-3 key fob connect the key switches. Solder a diode to each key switch pin. This will shield the pins from current, and prevent them from getting shorted. A diode permits current to only flow in only one direction. It features a visual indicator, a black band, that indicates which direction current will flow.

Sanabria says that some of the tools offered in auto parts stores, such as the Autel MaxiIM IM608PRO or IM508, can help customers who are shopping or DIY users to program replacement keys and restore data from the immobilizer. The tools connect to OBD ports and help the customer through each step, making the process easier than replacing the car's computer.

Jump-starting the battery

The majority of people have a set in their trunk to start a car in an emergency, however it might not be the best option for vehicles with newer technology. These vehicles are equipped with digital and computers that communicate with one another. A voltage spike when a battery is hooked up to another could cause damage to these components and leave your car unable to drive.

Connect the cables to the vehicle 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 clear, unpainted metal surface underneath the hood of your disabled car. The engine block is a great alternative. Don't connect the black cable to the negative terminal of the dead battery, as this could trigger an ignition source that ignites 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 disconnecting them in reverse order.

Replacement Case

Many Saab owners only have one key for their car and if they lose that it's going to cost them. It's costly to add a key and requires replacing the CIM or TWICE in the case of older models. It's best to have a second key in the event of theft or other disaster and the most effective way is to buy an extra key as soon as you are able to. Don't purchase a used key, even it's "new." Keys that are claimed-new purchased from third-party sellers won't be effective and are almost guaranteed to fail in the most critical moment.

The dealer will charge you top dollar if you only have one working key. We can reset and reprogram the computer's EEEPROM for it to accept a new key without replacing the entire system. That can save you a significant amount of money. It's much cheaper than wait until you lose the sole key.
