Saab Key Programming

Saab cars made since 1994 feature an immobilizer mechanism that is based on codes for keys. Adding an extra key requires a new transponder, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

It can be costly. This is why you should always have a spare key on hand.

Transponder key

The transponder is a piece of key that has an electronic chip. The chip sends a signal when the key is put in the ignition. The car then analyzes the signal to determine if it matches that of the key. If the signals are the same the car will be able to unlock itself and begin. This is a great way to deter auto theft and keep your car secure from thieves.

Transponder keys could be an extremely popular accessory for automobiles, but they are not as secure as traditional keys made of metal. While the metal parts of a traditional key may be cut and copied however, a transponder is secured by an electronic chip. The chip has an unique code that is encoded into the car's system to identify it.

When a Saab key fob is used the car recognizes it and allows it to turn on. The car will only recognize the key fob when it has a chip that is unmodified and has been programmed to match. The car won't start in the event that the key is not programmed to match.

It is crucial to have a spare saab keys key. This is especially important for those who live in a rural region where there are numerous car thieves.

Saab cars are usually provided with two keys. If you own only one, you need to purchase an additional key as fast as you can. This is because if you lose it and the car is damaged, it will require a new CIM and the locking cylinders replaced. This can be expensive especially for cars that are used.

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 requires a significant deal of soldering. It's not a standard way to do it, but you must determine how to get a saab replacement key to connect and solder each column and row. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins to connect.

After the columns and rows are soldered, it's the time to connect them to key switches. Solder a diode to each key switch pin. This will shield the pins from current and prevent them from being shorted. A diode allows the flow of current to be in one direction, and it has an indicator in black that shows the direction in which current will flow.

A few of the tools that are available at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- can aid shop customers or DIY customers in some cases program replacement keys and saab key battery replacement restore lost immobilizer information, Sanabria says. The tools connect to the OBD port and guide the user through the process, making it more simple than replacing the computer inside the vehicle.

Jump starting the battery

A lot of people keep an item in their trunks to jump-start a vehicle in an emergency, but it may not be a good idea for newer cars. These cars have a variety of electronic devices and computers that communicate with one another. A surge in voltage when a battery is hooked up to another one could damage the components and render your vehicle unable to drive.

Connect the cables to the vehicle operating. Allow it to run for two minutes. Attach the red clip to the positive terminal of the battery that's good. (It will say "POS" or "+".) Attach the other end to a clean unpainted metal surface underneath the hood of the affected car. The engine block is a great choice. The black cable should not be connected to the negative terminal of the dead battery. This could cause a spark, which would ignite gasoline in the engine compartment.

Once the cables are connected, you should start the vehicle and let it run about five minutes. Then, disconnect them in reverse. Keep in mind that the battery on the Saab 9-3 gets recharged while you drive, so it will take a while to get the battery back to its original level. It is a good idea to purchase a spare key fob as soon as you can, because replacing the only working one requires the installation of a brand new computer module and a special program to convince it that your missing keys aren't trying to steal the car.

Replacement Case

saab key Battery replacement owners usually only have one car key, and if that is lost, they'll be charged. The reason is that it's expensive to purchase a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. It is best to have a backup key in the event of theft or other disaster the best solution is to purchase an extra key as soon as you can. Don't buy a secondhand key even if it's "new." Keys that are claimed to be new from sellers selling aftermarket keys won't perform and are almost certain to fail in the crucial moment.

Most locksmiths aren't able to help in the event that you only have one working key and the dealer will charge you high fees to replace the computer in your vehicle to make a replacement. We can reset and reprogram the computer's EEEPROM in order to be able to accept a replacement key without having to replace the entire system. This can save you a significant amount of money. It's also less expensive than waiting until you lose your sole key.
