The problem is that this can be very expensive. Always keep an extra set of keys in your possession.

Transponder key

The transponder keys are keys equipped with an electronic chip. It sends a signal back to the car when it is put into the ignition. The car checks to see whether the signal matches with the one on the key. If the signals are identical it will open itself and start. This is a great method to protect your vehicle from theft.

Transponder keys can be a popular addition to cars, but they are not as secure as traditional keys made of metal. The metal component of the traditional keys can be easily cut and copied, whereas a transponder has an electronic chip that protects it. The chip has a unique code programmed into the car's computer 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 if the device has a chip that is unmodified and has been programmed to match. The car won't start if the key is not programmed to match.

Wired key

Saab cars typically come with two keys upon purchase. If you have only one, you should purchase an additional key as fast as you can. This is because if you lose it the car will require an entirely new CIM and the locking cylinders replaced. This can be costly especially for cars that are used.

The next step is connecting the wires for columns and rows to your microcontroller. This is the most difficult part of the project and will require a lot of soldering. It's not a standard way to do it, but you must think about how to route 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 that you need to connect.

After the rows and column are soldered together, it is time to connect the key switches. Solder a diode to each key switch pin. This will shield the pins from current and prevent them from being cut off. The diode will only allow current to flow in one direction, and has a the black band as a visual indicator that indicates the direction current will flow.

Some of the tools available at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- may help shop customers or even DIY customers in certain cases programme replacement keys and recover lost immobilizer information, Sanabria says. The tools connect to OBD ports and guide the user through each step, making the process easier than replacing the vehicle's computer.

Jumpstarting the battery

Most people keep the set in their trunks to jump-start a vehicle in an emergency, but it may not be a good idea for vehicles that are newer. They have numerous computers and saab 9 3 key replacement digital devices that communicate with each other. A surge of voltage when the battery is connected another battery could damage the components, rendering your car undriveable.

Start the vehicle that is working and allow it to run for approximately two minutes before you connect the cables to the disabled one. Attach the red clip to the positive terminal on the good battery (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 would be a good choice. Don't connect the black cable to the negative terminal of the dead battery, as it could ignite an ignition source that ignites gasoline in the engine bay.

After the cables have been connected, you can start the vehicle and let it run for about five minutes. Then disconnect them in reverse. Remember that the battery on the Saab 9-3 gets recharged while you drive, so it may take some time for the battery to come back down again. You should invest in a second key fob, as soon as possible. Replacing the only one that works requires the installation and programming of a new computer chip.

Replacement case

Many Saab owners have only one key for their vehicle and if they lose that key, it will cost them. The reason for this is that it's costly to purchase a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It's recommended to have a second key in case of theft or other disaster, and the best way is to purchase a second key as quickly as you can. Even when the key is "new", it won't work.

Most locksmiths can't help you with a single working key and the dealer will charge you high prices to replace the computer in your car for a replacement. We can, however, reset and re-program your computer's EEPROM to accept the new key, without replacing the whole system. This could save you a great deal of money. It's more affordable than wait until you loose the only key.
