saab 9-3 key replacement Key Programming

saab replacement key programming cars made since 1994 have an immobilizer system that is based on codes for keys. A new transponder is required to allow the addition of an additional key, as well as special programming. This is usually done by the dealer using a special Tech2 diagnostic tool.

This can be expensive. This is why it is important to always have a spare key at hand.

Transponder key

The transponder key comes with an electronic chip that transmits a signal to the car when it is placed in the ignition. The car is able to check whether the signal matches with the one on the key.

The car will recognize the saab 9-3 key fob programming keyfob, and allow it to be turned on. But, it's only able to do so if the key fob is unmodified and has a chip that has been programmed to match it. The car won't start in the event that the key has not been programmed to match.

Saab cars typically come with two keys when they're new. If you only have one, it is recommended to get an extra key as soon as you can. This is because if it's lost, the car will need an entirely new CIM and the locking cylinders replaced. This can be costly particularly for used cars.

The next step is connecting the wires of columns and row to your microcontroller. This is the most challenging part of the project and requires a significant amount of soldering. It's not a common way to go about it, but you should determine how to route and solder each column and row. There are 22 microcontroller wires and pins to connect for this keyboard. It includes 5 rows and 17 column.

Once the rows and columns are soldered, it's time to connect them to the key switches. Solder a diode on each key switch pin. This will protect the key switch pins from current and prevent them from being shorted. The diode allows current to only flow in only one direction. It is equipped with a visible indicator of a black line that shows which way current will flow.

Sanabria states that a number of the tools sold in auto parts stores, including the Autel MaxiIM IM608PRO and the IM508 can assist customers shopping or DIY customers to program replacement keys and restore immobilizer information. The tools connect to the OBD port and automatically guide the user through the procedure, making it simpler than replacing the computer in the vehicle.

Jump-starting the battery

A majority of people keep the set in their trunks to jump-start a car in an emergency, but it might not be the best option for vehicles with newer technology. These vehicles are equipped with numerous electronic devices and computers that communicate with each other. A surge of voltage when batteries are connected to another could cause damage to the components making your car inoperable.

Attach the other end of the black cable to an unpainted, clean metal surface underneath the disabled car's hood. The engine block is a good choice. The black cable is not to be connected to the negative terminal of the dead battery. This could trigger sparks, which could ignite the gasoline in the engine compartment.

It's expensive to purchase an additional key and it requires replacing the CIM or TWICE in the case of older models. In the event of theft, or any other disaster, it is best to have an extra key.
