saab 900 key Key Programming

Saab cars made since 1994 feature an immobilizer system that is based on coded keys. To add an additional key, you need the purchase of a new transponder as well as special programming. This is usually done at the dealer using a Tech2 diagnostic tool.

The problem is that this could be quite costly. This is why it is important to always have a spare key on hand.

Transponder key

The transponder key is a piece of hardware equipped with an electronic chip. It sends a signal to car when it is placed in the ignition. The car is able to check whether the signal matches with the one on the key. If the signals are in sync, the car will open and start. This is a great method to deter car theft and keep your vehicle safe from thieves.

Transponder keys can be an extremely popular accessory for cars, but they're not as safe as traditional metal keys. While the metal component of a traditional key can be cut and copied however, a transponder is secured by an electronic chip. This chip contains an unique code which is programmed into a car's computer in order to identify it.

The car will recognize the Saab keyfob, and allow it to turn on. The car will only recognize the key fob when it has a chip that is unmodified and programmed to match. The car won't start if the key is not programmed to match.

It is important to have a spare saab 9-5 Key replacement key. This is particularly important especially if you live in a rural region that has many car thieves. The good thing is that you can find a new key for your Saab without needing to visit a dealer and pay the high costs that they demand. In the majority of instances, you can get a new key made on-the-spot at a fraction of the cost of what you would pay at dealerships.

Wired key

Saab cars usually come with two keys upon purchase. If you only have one, it's best to acquire an additional key fob as soon as is possible, because if you lose it, the car will require an entirely new CIM unit and the locking cylinders have to be replaced. This could be expensive, especially if you are buying a second-hand car.

The next step is to connect the wires for columns and row to your microcontroller. This is the most difficult part of the project and it will require lots of soldering. There is no standardized way to do this, but it is crucial to plan the routes you'll use to solder the columns and rows. There are 22 microcontroller wires and pins to connect to this keyboard. It has five rows and 17 columns.

After the columns and rows are soldered, it's the time to connect them to the key switches. Solder a diode on each key switch pin. This will shield the pins that are used for key switches from current and also prevent them from being shorted. A diode can only allow the current to flow in a single direction, and has a an indicator Saab 9-5 key replacement 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 -- can help customers in the shop, or even DIY users in some cases program replacement keys and restore lost immobilizer information, Sanabria says. The tools connect to the OBD port and automatically guide the customer through the process, making it more simple than replacing the computer inside the vehicle.

Jump-starting the battery

The majority of people have the set in their trunk to jump start a vehicle in the event of an emergency, but it might not be a good option for vehicles with newer technology. These vehicles are equipped with digital and computers that communicate with each other. A voltage spike when the battery is connected to another battery could fry the components and render your car undriveable.

Start the vehicle you are using and allow it to run for approximately two minutes before you connect the cables to the one that is disabled. 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 vehicle's hood. An engine block is a good option. Don't connect the black cable to the negative terminal of the dead battery because it could ignite an ignition that ignites the gasoline in the engine bay.

Once the cables are connected, you should start the vehicle and allow it to run for around five minutes. Then disconnect the cables in reverse. Keep in mind that the battery on your Saab 9-3 is recharged during your drive, which means it will take a while to get the battery back to its original level. You should purchase an additional key fob when you can. Replacing the one that works requires the installation and programming of a new computer chip.

Replacement case

Many Saab owners only have one key for their car and if they lose that it's going to cost them. The reason is that it's not inexpensive to purchase a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. In the event of theft or any other calamity, it is best to have a spare key. Don't purchase a used key, even when it's "new." Keys that are claimed as new from a second-hand store will not work and are likely to fail at the crucial moment.

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