Saab 9-3 Key Not Accepted Contact Service Key Programming

Saab cars manufactured since 1994 have an immobilizer feature based on coded keys. A new transponder is required for inclusion of an additional key, and special programming. This is usually done by the dealer using a special Tech2 diagnostic tool.

It can be costly. You should always keep an extra set of keys in your possession.

Transponder key

The transponder is a type of key that has an electronic chip. The chip sends a signal when the key is put into the ignition. The car will then check the signal to determine whether it is identical to the one that is in the key. If the signals are in sync the car will then unlock and start. This is a great way to stop auto theft and keep your vehicle secure from thieves.

Transponder keys are a popular 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 or copied, while transponders are protected by an electronic chip that safeguards it. This chip contains an unique code which is programmed into the car's computer in order to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. However, it will only do this if the fob has a non-modified chip that has been programmed to match it. The car will not start in the event that the key has not been programmed to match.

Wired key

Saab cars are usually supplied with two keys. If you only have one, it is best to acquire an extra key fob as soon as is possible, because if you lose it the car will require an entirely new CIM unit, and the locking cylinders will need to be replaced. This can be costly, especially for used cars.

The next step is to connect the row and column wires to the microcontroller. This is the most challenging part of the project and requires a significant deal of soldering. There is no standardized way to do this, but it's important to plan out the routes you'll use to solder the rows and columns. There are 22 microcontroller wires and pins that you can connect to this keyboard. It has five rows and 17 column.

Once the rows and columns are soldered, it's time to connect them to key switches. Solder a diode to each key switch pin. This will shield the pins from current, thus preventing them from being shortened. A diode can only allow the current to flow in a single direction, and saab 9-3 key not accepted contact service it has an indicator in black that indicates which way the current will flow.

Sanabria states that a number of the tools offered in auto parts stores, such as the Autel MaxiIM IM608PRO or IM508 are able to assist customers shopping or DIY customers to program replacement keys and restore data from the immobilizer. The tools plug into OBD ports and guide the customer through each step which makes the process much easier than replacing the vehicle's computer.

Jumpstarting the battery

Most people keep a few sets of jumper cables in their trunk to use in an emergency, but jumping a battery on modern vehicles may not be the most efficient option. These vehicles are equipped with many electronic devices and computers that communicate with one another. A voltage surge while the battery is connected to another could cause damage to these components, rendering your car undriveable.

Start the working vehicle and let it run for about two minutes before you connect the cables to the non-working one. 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 a clean, unpainted metal surface beneath the damaged car's hood. The engine block would be an ideal choice. The black cable should not be connected to the negative terminal of the dead battery. This could create a spark, which would ignite gasoline in the engine compartment.

Once the cables are connected the disabled vehicle and let it run for about five minutes before disconnecting them in reverse order. The battery in the Saab 9-3 will charge while you drive. It takes a while for it to fall back. It's a good idea to buy a spare key fob as soon as you can, since replacing the only working one requires the installation of a new computer module and a special program to convince it that your missing keys aren't in the process of trying to steal the car.

Replacement Case

Many saab 9-3 key not accepted contact service owners only have one key for their car and if they lose it, saab 9-3 key not accepted Contact service the cost will be. The reason is that it's expensive to add 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 calamity it is best to have a spare key. Even if the key is "new", it will not function.

The dealer will charge you the highest dollar for only one working key. We can, however, reset and re-program your computer's EEPROM to prepare it to accept an alternative key without replacing the entire system. This could save you a lot of money. It's more affordable rather than wait until you loose the only key.
