This is a great method to protect your car from theft.

Transponder keys could be a popular addition to cars, but they're not as safe as traditional keys made of metal. The metal component of a traditional key can easily be cut and copied, whereas transponders are protected by an electronic chip that safeguards it. The chip contains a unique code that is inserted into a car's computers in order to identify it.

The car will recognize the Saab keyfob and allow it to turn on. However, it can only do this if your key fob is unmodified and has a chip that has been programmed to match the original. Otherwise, the car will refuse to accept the key and will not start.

This means there will be 22 microcontroller pins and wires to connect.

Once the rows and columns are soldered, it's the time to connect them to the key switches. To do this, put an inverter over each pin on the key switch and then solder it. This will shield the pins of the key switch from current and also prevent them from being shorted. A diode allows the current to flow in a single direction, and it also has a an indicator in black that indicates which way the current will flow.

Some of the tools available at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 -- could help shop customers or even DIY customers in certain cases replace keys in the program and restore the lost immobilizer's data, Sanabria says.

Jump-starting the battery

Most people keep a few sets of jumper cables in their trunk for emergencies, but jumping a battery on modern vehicles may not be the best idea. These vehicles are equipped with numerous electronic devices and computers that communicate with one another. A voltage spike when the battery is connected to another can fry these components, rendering your vehicle unable to drive.

Connect the cables to the vehicle operating. Let it 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 of the black cable to a clean, unpainted metal surface beneath the damaged vehicle's hood. An engine block is an excellent choice. The black cable should not be connected to the negative terminal of the dead battery. This could cause sparks that could ignite the gasoline that is in the engine compartment.

Be aware that the battery in your Saab 9-3 is charged during your drive, which means it can take a while for the battery to come back to normal.

Replacement Case

Saab owners often only have one car key, and if that is lost, they will be charged. It's expensive to buy an additional key and it requires replacing the CIM or TWICE in the case of older models. It's best to have a spare key in the event of theft or other disaster and the most effective way is to buy an extra key as soon as you are able to. But don't buy a used key even it's "new."

The majority of locksmiths won't be able to help in the event that you only have one working key, and the dealer will charge you high prices to replace the computer in your vehicle to create a replacement. We can, however, reset and reprogram the computer's EEPROM to accept the new key, without replacing the whole system. This could save you a lot of money. It's also less expensive than waiting until you lose your only key.
