Saab Key Programming

saab spare key cars built since about 1994 come with an immobilizer system that is based on codes for keys. To add an additional key, you need the purchase of a new transponder as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

The issue is that this could be extremely expensive. It is recommended to always have an extra set of keys at hand.

Transponder key

The transponder key comes equipped with an electronic chip. It sends a signal back to the car when it is inserted into ignition. The car is able to check whether the signal is the same as the one on the key. If both signals match the car will be able to unlock itself and start. This is a great way to deter car theft and keep your vehicle safe from thieves.

Transponder keys may be an increasingly popular feature for automobiles, but they are not as safe as traditional keys made of metal. The metal portion of a traditional keys can be easily cut and copied, however the transponder is protected by an electronic chip that safeguards it. This chip contains an unique code that is inserted into a car's computer order to identify it.

This is because, if it's lost, the car will need 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 large amount of soldering. There is no standardized way to do this, but it is crucial to plan the route you'll take and solder the columns and rows. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins to connect.

After the columns and rows are soldered, it's time to connect them to the key switches. To do this you must place a diode on each pin on the key switch and then solder it. This will protect the pins from current, thus preventing them from being cut off. A diode allows current to only flow in only one direction. It has a visual indicator of a black line that indicates the direction in which current will flow.

Sanabria says that some of the tools that are sold in auto parts stores, like the Autel MaxiIM IM608PRO or IM508 are able to 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 much easier than replacing the computer inside the vehicle.

Jump-starting the battery

A lot of people keep a set of jumper cables in their trunks for emergency situations, but jumping a battery on modern vehicles may not be the most efficient option. These vehicles are equipped with computers and digital devices which communicate with one another. A voltage spike when the battery is connected to another can fry these components, rendering your car undriveable.

Start the working vehicle and allow it to run for around two minutes before connecting the cables to the disabled one. Attach the red clip to the positive terminal of 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 is a good option. Don't connect the black cable to the negative terminal on the dead battery as this could cause an ignition spark that ignites the gasoline in the engine bay.

After the cables have been connected, you can begin the car and allow it to run for around five minutes. Then disconnect the cables in reverse. Be aware that the battery in your Saab 9-3 is charged when you drive, and it may take some time for the battery to come back down again. It is a good idea to invest in a spare key fob as soon as you can, because replacing the sole working one requires the installation of a new computer module and special programming to convince it that your missing keys are not trying to steal the car.

Replacement Case

Many Saab 9-3 key not accepted contact service (minecraftcommand.science) owners have only one key for their vehicle and if they lose it, key, it will cost them. It's expensive to buy a key and requires replacing the CIM or TWICE for older models. In the event of theft, or other catastrophe, it is best to have a spare key. Don't buy a secondhand key even if it's "new." Keys that are claimed-new purchased from third-party sellers won't work and are likely to fail at the crucial moment.
