Saab cars built since about 1994 feature an immobilizer mechanism that is based on codes for keys. To add an additional key, you need the purchase of a new transponder as well as special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

It can be costly. You should always keep a spare set of keys in your possession.

Transponder key

The transponder is a piece of key with an electronic chip. This chip sends a signal when the key is placed in the ignition. The car will then check the signal to determine if it matches the one on the key. If the signals are in sync it will unlock and start. This is a great method to guard your car against theft.

Transponder keys are an increasingly popular feature in cars, but you should be aware that they're not as secure as classic metal keys. The metal portion of a traditional key can be easily cut and copied, whereas the transponder is protected by an electronic chip that safeguards it. The chip has a unique code 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 fob has an unmodified chip that has been programmed to match. The car won't start in the event that the key is not programmed to match.

It's crucial to ensure that you have an extra key for your saab 9-3 key not accepted contact service.

Wired key

Saab cars are usually delivered with two keys. If you have only one, it is best to acquire an additional key fob as soon as you can since if you lose it, the car will require a new CIM unit and the locking cylinders will need to be replaced. This could be expensive especially if you're purchasing a used vehicle.

The next step is to connect the wires for columns and rows to your microcontroller. This is the most tedious aspect of the project and will require a lot of soldering. It's not a standard way to do it, but you should determine how to route and connect each column and row. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller pins and wires to connect.

This will protect the pins from current, preventing them from getting shorted. A diode only allows current to flow in one direction, and it has a black band visual indicator that indicates the direction in which current will flow.

Sanabria states that a number of the tools available in auto parts stores, such as the Autel MaxiIM IM608PRO or IM508 will assist customers shopping or DIY customers to program replacement keys and restore immobilizer data. The tools connect to the OBD port and guide the customer through the process, making it more simple than replacing the computer in the vehicle.

Jump-starting the battery

The majority of people have a set of jumper cables in their trunks for emergency situations however, jumping a battery on modern automobiles might not be the best option. These vehicles are equipped with a number of computers and digital devices that communicate with each other. A surge in voltage while a battery is hooked up to another battery could fry these components and render your car unable to drive.

Start the working vehicle and let it run for about two minutes before connecting the cables to the battery that is not working. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end to a clean, unpainted metal surface beneath the hood of the disabled car. The engine block is a good option. 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, begin the car and allow it to run for around five minutes. Then, disconnect the cables in reverse. The battery in your Saab 9-3 will recharge as you drive. It takes a while for it to fall back. It is recommended to purchase an additional key fob when you can. Replacing the only one that works requires the installation and programming of a new computer chip.

Replacement case

Many saab 93 key programming owners have only one key for their vehicle and if they lose that the cost will be. 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 is best to have a second key in the event of theft or other disaster, and the best way is to buy an extra key as soon as you are able to. However, don't purchase a secondhand key, even the case that it's "new." Keys that are claimed to be new from a second-hand store will not be effective and are almost guaranteed to fail in the crucial moment.

Most locksmiths aren't able to help with a single working key and the dealer will charge for the cost of replacing the computer in your car to create a replacement. However, we can reset and re-program your computer's EEPROM in order to prepare it to accept a new key without replacing the entire system. This could save you a great deal of money. It's less expensive than wait until you lose the sole key.
