The issue is that this could be quite costly. It is recommended to always have a spare set of keys on hand.

Transponder key

The transponder key is a key equipped with an electronic chip. It sends a signal back to the car when it is put into the ignition. The car is able to check whether the signal matches with the one on the key. If the signals match the car will then unlock itself and begin. This is a great way to protect your car from theft.

Transponder keys are an increasingly popular feature for cars, but they are not as safe as traditional metal keys. The metal portion of a traditional key can easily be cut or copied, while transponders have an electronic chip that guards it. This chip has a unique code programmed into the car's computers to identify it.

The car will recognize the Saab keyfob and permit it to be turned on. The car can only recognize the key fob if it has a chip that is unmodified and programmed to match. Otherwise, the car would refuse to accept the key and will not start.

Saab cars are usually supplied with two keys. If you have only one, it's recommended to purchase an additional key fob as soon as possible since if you lose it, your car will require an entirely new CIM unit and the locking cylinders will have 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 toughest aspect of the project and it will require lots of soldering. There is no standardized way to accomplish this, however it's important to plan out the routes you'll use to solder the rows and columns. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller pins and wires to connect.

After the columns and rows are soldered together then it's time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins from current, thus preventing them from being shorted. The diode will only allow the current to flow in a single direction, and has a an indicator of black color that shows the direction in which current will flow.

A few of the tools that are available at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- could aid shop customers or DIY customers in some cases create replacement keys and restore lost immobilizer data, 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 majority of people keep an item in their trunks to jump-start their car in case of emergency, but this might not be the best idea for vehicles that are newer. They have numerous electronic devices and computers that communicate with each other. A surge in voltage while a battery is hooked up to another one could damage these components and render your vehicle undriveable.

Start the vehicle that is working and let it run for about two minutes before connecting the cables to the disabled one. Attach the red clip on the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end to a clean and unpainted metal surface beneath the hood of the damaged car. The engine block is an excellent choice. Don't connect the black cable to the negative terminal of the dead battery as it could ignite an ignition that ignites the gasoline in the engine bay.

After the cables have been connected, start the vehicle and let it run about five minutes. Then, disconnect them in reverse. The battery in the Saab 9-3 will charge while you drive. It takes a while for it to fall back. It is a good idea to purchase a spare key fob as soon as you can, since replacing the sole working one requires the installation of a new computer module and a special program to convince it that the lost keys aren't in the process of trying to steal the car.

Replacement Case

Many saab 9-3 key not accepted contact service owners have only one key for their vehicle and if they lose that key, it will cost them. It's expensive to add a key and requires replacing the CIM or TWICE for older models. In the event of theft, or any other disaster, it is best to have an extra key. However, don't purchase a secondhand key, even when it's "new." Keys that are claimed-new purchased from third-party sellers won't work and are almost guaranteed to fail in the crucial moment.

The dealer will charge the highest dollar if you only have one working key. We can reset and reprogram the EEEPROM of your computer for it to accept a replacement key without having to replace the entire system. This can save you a great deal of money. It's also a lot cheaper than waiting until you lose your sole key.
