saab 9-3 key not accepted contact service Key Programming

saab 93 key fob cars built since 1994 feature an immobilizer that relies on keys that are coded. A new transponder is required for the addition of an extra key, and special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

The issue is that this could be very expensive. This is the reason why you should always have a spare key available.

Transponder key

The transponder is a type of key that is equipped with an electronic chip. The chip sends a signal when the key is inserted into the ignition. The car then checks the signal to determine if it matches that of the key. If both signals match it will open itself and start. This is a great way to stop auto theft and keep your vehicle secure from thieves.

Transponder keys may be an increasingly popular feature for cars, but they are not as safe as traditional metal keys. The metal part of the traditional keys can be easily cut and copied, whereas the transponder is protected by an electronic chip that safeguards it. The chip has a unique code that is inserted into a car's computer order to identify it.

The car will recognize the Saab keyfob and permit it to turn on. But, it's only able to do this if the fob is unmodified and has a chip that has been programmed to match. Otherwise, the car will reject the key and won't start.

Wired key

Saab cars are usually delivered with two keys. If you own only one, you should purchase an extra key as soon as you can. This is because if it's lost and the car needs a new CIM and the locking cylinders replaced. This can be costly particularly if you are purchasing a used vehicle.

The next step is connecting the row and columns wires to your microcontroller. This is the toughest component of the project and it will require a lot of soldering. There is no standardized way to accomplish this, however it is essential to determine the route you'll take 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 joined It is now time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins that are used for key switches from current and also prevent them from being shorted. The diode will only allow current to flow in one direction, and it has an indicator of black color that indicates the direction in which current will flow.

Sanabria says that some of the tools that are sold in auto parts stores, such as the Autel MaxiIM IM608PRO and the IM508 can assist customers shopping or DIY customers to program replacement keys and restore data from the immobilizer. The tools plug into 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

A lot of people keep an assortment of tools in their trunks to jump-start a car in an emergency, but it might not be a good idea for cars with more modern technology. These vehicles are equipped with many computers and digital devices which communicate with one another. A voltage spike when batteries are connected to another battery could damage the components and render your vehicle unusable.

Connect the cables to the vehicle operating. Let it run for two minutes. 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 underneath the disabled 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 trigger a spark, which would ignite the gasoline that is in the engine compartment.

Once the cables are connected, you can start the vehicle you are not using and let it run for approximately five minutes before disconnecting the cables in reverse order. Be aware that the battery of your Saab 9-3 is recharged while you drive, so it could take a while to get the battery back down again. It's a good idea purchase a spare fob as soon as you can, because replacing the only working one requires the installation of a brand new computer module and special programming to convince it that your missing keys aren't attempting to steal the car.

Replacement Case

Many Saab owners only have one key for their car and if they lose it, it's going to cost them. It's costly to add keys and will require replacing the CIM or TWICE in the case of older models. It is recommended to have a backup key in the event of theft or any other catastrophe and the most effective way is to purchase a second key as soon as you can. Even it's "new" it will not function.

The dealer will charge you the most expensive dollar if you have only one working key. We can reset and reprogram the computer's EEEPROM in order for it to accept a replacement key without replacing the entire system. This can help you save money. It's much cheaper than wait until you lose your only key.
